2-in-1 type, two sets of parameter detection and display
(PH+ORP/PH+residual chlorine/PH+conductivity)
Simultaneously display two sets of parameter measurement values, including temperature.
The operation of the flywheel knob is more convenient.
Microprocessor technology, digital analyzer, wall mounted installation, LCD display screen.
ABS material shell, corrosion-resistant, compliant withIP65Protection level.
Provide two types of set point outputs: ON/OFF or time proportional (can be connected to a control metering pump).
Equipped with sampling water flow detection standby, external signal control standby, medicine barrel liquid level alarm, alarm output, password operation protection, startup delay start function, RS485 communication interface.
Optional mA output, GSM/GPRS communication module with short message (SMS) alarm or remote control function.
Function model description
