This product features high stability, excellent repeatability, and multiple signal outputs, enabling accurate measurement of conductivity values, acid-base concentration values, and temperature values in solutions.

Scope of Application:

Widely used for online detection of conductivity values in solutions across environmental protection, wastewater treatment, thermal power, aquaculture, food processing, printing, metallurgy, pharmaceuticals, fermentation, chemical engineering, and more.

Main Features:

◇ Large-screen dot-matrix LCD display with Chinese menu operation.

◇ Capable of conductivity measurement, upper/lower limit control, and standard current transmission.

◇ Screen displays alarm status accompanied by ON/OFF signal output.

◇ Automatic temperature compensation function: automatic compensation from 0 to 60°C or 95°C.

◇ Communication function (optional): Equipped with RS-485 communication interface (partially compatible with MODBUS protocol), 4–20 mA current output corresponding to conductivity values can be arbitrarily set.

◇ Watchdog function: Ensures the instrument does not freeze.

◇ Factory settings can be restored. Power-off protection >10 years.
