Lishtot's proprietary technology platform uses electric field sensors to determine the profile/quality of a given water sample. This technology is at the heart of all of our water quality detection devices, including the TestDrop Pro and the follow-on TeStraw and TestPipe.
Our technology is premised on fundamental chemical principles; the interplay between water and a testing cup generates a distinctive electric field. Contaminants present in the water will cause interference, leading to the creation of a distorted electric field. These field distortions will vary depending on the type of contamination in the water, whether from bacteria, organics, heavy metals, pesticides, or toxins
The sensors embedded in our devices are calibrated to measure the electric fields associated with the presence of water and are sensitive enough to detect the field distortions created by different contaminants. Our sensors can therefore determine the quality of the water by the nature of the electric fields measured around the cup. The sensor records a result on the device, signals the result with a red or blue light, and sends the data to the Lishtot mobile app (Bluetooth connection depending) where further details can be accessed.
The technology is sensitive to anything that isn't supposed to be in water, as evidenced by the extensive list of contaminants that Lishtot products can detect. At the same time, the technology is not disrupted by the presence of substances that are supposed to be in clean water, such as soil, salt, and magnesium. Default device settings are calibrated to World Health Organization guidelines for drinking-water quality but can be adjusted individually through the app to different levels of water quality. Additionally, our personal water tester, the TestDrop Pro is equipped with three buttons, to allow the testing of different types of water (tap, bottled, and natural) against different criteria for contamination detection.
