e-sens manufactures a new generation of hand-held instruments that dramatically simplifies the process of testing water quality. Combining silicon-based sensors with powerful microfluidics, the e-sens device eliminates cumbersome solutions and reagents and increases accuracy through auto-calibration and minimal user interaction. With the touch of a button, the e-sens device processes and transmits data on 22 different water quality parameters to any mobile device. The mobile app tracks and uploads test data onto any server for long-term analytics. This new digital approach saves time, reduces cost, provides greater user-to-user consistency, and makes it easier for testers to perform analyses.
