Industrial Test Systems (ITS) announces the release of its eXact® Micro 20 dual-wavelength photometer. This waterproof (IP-67) unit quickly does on-site testing for over 30 direct-read water quality parameters without lookup tables, providing lab-quality accuracy at minimal cost. It features a narrow-band wavelength filter for optimal accuracy, long-life LEDs and a built-in cell for ultra-performance. Each parameter stores the 20 previous results for a total of over 600. This high-quality unit self-calibrates and automatically selects the optimal wavelength (525 nm or 638 nm) for each parameter. http://www.sensafe.com, mmcbride@sensafe.com
