The integrated two-wire PHG-2518 industrial acidity meter is a two (four) wire transmitter type intelligent industrial acidity meter developed by our company. It adopts a new design mode, high performance, high reliability, LCD display, and is specially developed for measuring acidity in water quality in industries such as chemical, power station, electronics, and fermentation.

PHG-2518 acidity meter is an industrial type acidity meter used for continuous measurement. The preamplifier adopts a high impedance amplifier, and the pH electrode adopts an imported composite electrode. Instruments have the characteristics of high measurement accuracy, fast response speed, small size, and easy installation and maintenance.

The instrument adopts a two-point calibration method, with a two-wire 4-20mA output; The four wire system adopts 24V power supply and 4-20mA output. Due to the use of current to transmit pH signals, the instrument has strong anti-interference ability and a long transmission distance, with a transmission distance of up to 200 meters.

Instrument features:

Adopting a single-chip microcomputer, with low power consumption, few peripheral devices, high performance, high stability, and high reliability.

LCD display, buttons can display acidity value, mV value, and temperature value respectively.

Parameter power-off protection.

Equipped with two-point or one point automatic calibration function, convenient and accurate.

Automatic temperature compensation.
