Introduction
It is a compact panel-mounted online continuous detection redox [ORP] controller, measuring range: ±1000mV
Equipped with a large LCD display with protective cover and backlight, single set point, single output for oxidation or reduction dosing settings, manual two-point calibration through the panel, analog output: 0 to 20 mA or 4 to 20 mA [ isolationã
Manual ON, OFF and automatic quantitative control can be selected for oxidation or reduction quantitative dosing settings; the automatic diagnostic function can verify offset and slope calibration as well as electrode contamination or failure, and the fail-safe alarm system can prevent power failure or signal interruption. and caused problems.
