PH/ORP instrument

Suitable for industrial applications with precise pH/ORP control, as well as various complex on-site environments. Ultra strong anti-interference design: outstanding performance in strong interference field operations. NEMA4X, IP65 protection level: all-weather waterproof and gas resistant. Secondary password protection: prevents unauthorized changes to settings. ● Multi line display LCD screen; High brightness LED orange backlight that can be freely switched on and off. Control mode: Proportional Pulse Width Control (PLC) or Switching Control (LIT). ● Two way relay contact switch: can independently set high and low point control and hysteresis band width. ● Third channel cleaning/alarm function relay: Users can set the cleaning frequency and time themselves. Multiple current output options: 0/4-20mA, output range can be set by oneself. Two electrode input methods: asymmetric input/symmetric input. ● pH/mV/temperature reading offset adjustment: Compare the on-site online verification values. Optional antimony electrode: used for measurement in ***** environment. ● Process temperature (TST1) and calibration temperature (TST2) can be set, with precise temperature compensation.
