Operation and maintenance is simple and economical; no zero point calibration is needed and the analyzer has no moving parts. It requires only periodic calibration, electrolyte and membrane cap replacement.

The PAA sensor is available for ranges 0-500, 0-20,000 and 0-50,000 mg/l (ppm). The hydrogen peroxide sensor is available for ranges 0-500, 0-10,000, 0-20,000 and 0-50,000 mg/l (ppm). Both are designed for applictions including food, beverage, dairy and pharmaceutical processes.

Results are displayed on a 4.3" full color LCD touch screen interface rated for a minimum 1 million touches on any one point. The screen displays concentration, high / low disinfectant alarm, flow status and alarm (optional item), and processor status.
