PHS-8B Intelligent Industrial pH/ORP Transmitter

Introduction

PHS-8B intelligent industrial PH transmitter is the intelligent industrial online analytical instrument. It can be connected to the high-impedance analog signal pH ORP electrode of many companies at home and abroad. It can be used to detect the pH, ORP value of the solution in chemical, petroleum, rubber, paper, tobacco, alcohol, sugar, food, mining, smelting, iron and steel, power generation, pharmaceuticals, water treatment and other industries.

 Feature

1 16 bit high accuracy AD and low power microprocessor technology.

2 Multi-level password protection, reliable and safe measurement data.

3 Automatically identify and calibrate the PH standard solution. Automatic temperature compensation

4 High-resolution graphic LCD which can display the PH (mV) value, temperature, date, electrode slope, zero position, output current, etc. simultaneously.

5 Two analog (pH/mV and temperature) isolated output and digital signal output (RS485/ standard MODBUS protocol) can be chosen.

6 4-way alarm relay and 1-way cleaning control relay output

7 Isolated power supply is adopted to measure and output. Strong anti-interference ability.

8 Intelligent paperless record and power-off protection can record and inquire the operation of a month~a year and set data.
