Simultaneously display both pH and ORP parameters, including temperature values.
The automatic dosing control system for water quality analyzer and metering pump is compact in structure and fully equipped.
Flywheel knob operation, user-friendly design, intuitive and easy to operate.
After connecting the sampling water source and dosing pipe, it can be used by powering on, making installation simple and reducing on-site assembly and construction time.
Wall mounted installation, IP65 rating, bottom plate made of acid, alkali and corrosion-resistant material.
The discharge flow rate of the metering pump is selected according to actual needs, with high flexibility.
The sampling cup has a water flow detection function to ensure correct measurement values and safe dosing.
The water flow detection standby control function can put the analyzer into standby mode when the sampled water stops flowing, pause the output to control the dosing of the metering pump, and automatically return to normal working state after the signal disappears.
Paired with temperature electrodes, it can provide manual/automatic pH temperature compensation and display temperature values.
