The eXact Micro 20 dual wavelength photometer delivers sustainable, cost-effective water testing solutions. It is waterproof (IP-67) and quickly does onsite testing for more than 35 direct-read water quality parameters without lookup tables, counting drops or matching colors. It features a narrow-band wavelength filter for optimal accuracy, long-life LEDs and a built-in cell. The unit self calibrates and automatically selects the optimal wavelength for each parameter.
