Planning a trip to India, China, or anywhere else in the world? The tap water in many countries is contaminated with viruses, bacteria, parasites, and disease-causing chemicals. Unfortunately, this is the case in many popular tourist destinations. This water is unsafe for drinking, preparing food and beverages, making ice, cooking, and even brushing teeth. The TestDrop Pro is light enough to fit on your keychain so you can test water on the go.
The TestDrop Pro is the first IoT water testing device. Use Bluetooth to sync with the Lishtot App to track your testing history and obtain your water score. The only water app you’ll ever need, the Lishtot App is available for download on the App Store and Google Play.
TestDrop is the most convenient and inexpensive way to regularly test your water for contaminants. Most people have no idea about the quality of the water they drink, and for such an important and life-sustaining resource, people should know more. Whether you're hiking outdoors, traveling to another country, interested to know what's coming out of your home tap or just looking to know how your bottled water compares to your tap water, TestDrop is here to provide answers.
TestDrop allows you to test any type of water. By simply pouring a water sample into a plastic cup, and taking a reading with the TestDrop next to the cup, you can know by the blue or red lights if certain contaminants have been identified in the water. You can also send the recent tests you've done to the app, take a video, add your tests to the Lishtot Global Water Map, and/or learn more details about the level and type of contaminants in your drinking water. There is no contact between the TestDrop and the water, and there is no requirement for adding chemicals or waiting for some reaction. The whole process is complete in 5 seconds.
The TestDrop should be used anywhere and everywhere possible for testing your drinking water. Part of our goal at Lishtot is to help the world know more about its water, and to achieve that we are building a Global Water Map which gets better with more user-generated information. You can test tap water, bottled water, and natural water like streams and rivers. You can test filtered water and distilled water. At home, at work, and in the wilderness. In public water fountains and restaurants. Any type of water that you want to drink, you can test.
Please email us at email@example.com for information on large purchases.
You can use the device for thousands of tests and will get the blue or red LED response. Greater detail such as graph appearance and likelihood of contamination will require use of a Bluetooth-supported app available for smartphones.
Based on well-known chemistry principals, the patented technology behind the TestDrop and future products to be sold by Lishtot detect electric fields associated with the presence of water. If contaminants are present, those electric fields are distorted in various ways, depending on the type of contaminant present in the water. The sensor records a result on the device, and then via a Bluetooth connection can send the information to the Lishtot mobile app for further details.
The TestDrop does not need to be connected to the internet, partly because we want people to be able to use this device anywhere, including at the supermarket and in the wild. The device can perform an unlimited number of tests without having to send data to our mobile app. The last ten tests you run will be transferred to the app once you send data from your device to your phone.
The core technology behind Lishtot's products detects electric fields that are related to water. These fields are generated and altered by interactions with contaminants, and in order to view those interactions, a vessel is needed in order to watch the interplay between water, contaminants, and the vessel itself. Flowing water simply does not produce this detectable electric field. Furthermore, it is also much simpler to get an accurate and reliable result with a sample of water in a still vessel.
This happens when the device is establishing a Bluetooth connection with the smartphone application. Please make sure your location and Bluetooth functionalities are turned on. This should take about 10 seconds before you can begin regular testing. If the blinking persists it could mean that your smartphone is having trouble connecting with the TestDrop. Please contact our customer support team at firstname.lastname@example.org so we can help you find a solution.
The issue probably has to do with a bad battery in the device. Please send an email to email@example.com and we will get that sorted out for you immediately.
The device is limited to an estimated 2000 tests due to battery life.
There are numerous reasons why this could be happening. It could be the water you are testing is in fact contaminated, or that the baseline standard in your location is below the baseline criteria that Lishtot has established for clean water. It can also be a result of not following the testing guidelines that Lishtot provides for using the TestDrop properly. Finally, it could be that the device is malfunctioning. Before reaching out to us, try to purchase several different brands of mineral water at the nearest store and pour into clean plastic cups and test them. If the TestDrop continues to indicate red, please contact firstname.lastname@example.org for more assistance.
Please ensure that your Bluetooth and location settings are turned on. The device should feature blinking red and blue lights to show that it is working to connect to your phone. If you are still unable to connect the device to your phone please email us at email@example.com.
When you swirl or tilt the water in the cup, you charge the cup. The detector can detect the electric fields associated with the cup. Protein, heavy metals, bacteria, organic pesticides and other materials interfere with the charging of the cup, leading to different fields. The sensor can determine the quality of the water by the electric fields it measures around the cup.
Try to find some clean water, possibly from an unopened plastic bottle of mineral water. Run a test as shown on the website. You should get a blue light. You can add a very small amount of soap or spit in the cup, swirl again, and test. You should get a red light that never goes back to blue after repeated testing. If so, your device is working properly.
We expect so. Please make sure that your app is up to date and that any new software for your TestDrop has been uploaded to the device.
The TestDrop gets the best results when done using plastic cups or water bottles. Any other material interferes with thesignal. The technology currently does not work with glass, ceramic, wood, or metal vessels. TestDrop is extremely sensitive to even the slightest contamination. For reusable bottles and glasses, even something that has been washed with soap and rinsed thoroughly, many times the TestDrop will detect that soap or other residual materials.
The TestDrop sensors are designed to work specifically with hydrophobic containers - containers that repel water. Our reason for designing this way is that, in the case of contamination, the contaminants will actually stick to the walls of the container, enabling Lishtot to detect even the most miniscule levels of contamination. Polypropylene (PP) and polystyrene (PS) are the best materials for testing. Look at the bottom of a cup and it should say PP or PS or have their corresponding recycling numbers, 5 or 6, respectively. PET cups (#1 printed on cups) may also be employed.
It is important to swirl the water in the container or tilt the cup in order toallow the water you are testing to interact with the exposed sides of the plastic cup. We suggest filling a cup to just over one-half full and swirling gently for about ten seconds, tilting on one side just until the water reaches the top of that side. Let the water settle. Measure in the "L" motion as shown in the How-To Videos.
We discourage reusing cups, especially if you have seen a red light. Contaminants may remain on the cup and interfere with future measurements.
In developing our technology, we found that different surfaces-wood, glass, plastic, metal, formica-have different effects on electric fields associated with the plastic cup. Holding the cup in one hand removes this problematic source of this signal "noise".
Bottled water can be placed on a table in order to conduct testing as per the demonstration video.
You should wait around 3 seconds between tests.
Try to get the water back into the water stack and have the sides dry if possible.
We have found that one does not have to touch the cup when doing a proper measurement. If you do touch the cup, the results should not be affected.
Polypropylene (PP) and Polystyrene (PS) are preferred plastics. Look for the PP 05 or PS 06 on the bottom of the cups you use for testing.
Generally no. There are some soft drinks that do work with the device, but in general the presence of numerous chemicals in soft drinks makes testing not possible.
We encourage users to test water at least once a day. You may test more frequently, as water providers often change their source of water several times in any given day.
Yes. Please see the videos on our website for how to check mineral water bottles prior to opening.
Extremely cold water that yields condensation on the outside of a cup or extremely hot water that produces steam and/or condensation on the inside of a cup will give a red light, even if the water is clean. Water should be between 20 and 50 degrees Celsius.
For best results, water from tap or bottle should be poured directly into a clean disposable cup for testing. One should avoid placing the water into a jug, glass or other container as such containers may impart impurities into the water prior to testing.
