Introduction

A pH meter is an electronic instrument used to measure the pH level, which indicates the acidity or alkalinity of a solution. The pH scale ranges from 0 to 14, where 7 is neutral, values below 7 indicate acidity, and values above 7 indicate alkalinity.

Application

Water treatment, sewage treatment, aquaculture,surface water monitoring, environmental engineering, cooling tower circulating water,beverages and foodstuffs, industrial wastewater discharge monitoring

Water treatment

Sewage treatment

foodstuffs

Advantages

1.LCD display with backlight, English operationinterface
2.Calibration and setting can set cryptoguard.Technical parameters can be set with buttonson site.
3.High stability, high accuracy, can measurePH,ORP and temperature.
4.Temperature compensation
5.Multiple output (2 relays,4-20mA).Supper anti-interference design can befor strong interference with field operationsand anti-electromagnetic interference.The built-in memory chip ensures that theparameters and calibration data are not lostwhen shut down or off normally.
6.Can automatically detect the temperatureprobe and enter the automatic temperaturecompensation program
