brief introduction

The PH transmitter is the PHSH-628 developed by our companyOne of the series of intelligent online chemical analyzers, it has strong environmental adaptability, simple operation, and excellent testing performance, making it highly cost-effective and capable of accurately measuring solutionsPH value. It can be widely used for continuous monitoring of pH values in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water. The transmitter adopts a cast aluminum shell with good sealing performance and a protection level of up to IP67, which is particularly suitable for industrial places with harsh on-site environments and unsuitable for prolonged personnel stay.

The transmitter adopts a two-wire system,24VDC power supply, simple wiring. Can output 4-20mA for display, recording, control, regulation and other instruments or PLC, DCS, FCS systems.

Basic functions

High intelligence: Explosion proof industrialThe PH/ORP transmitter adopts high-precision AD conversion and single-chip microcomputer processing technology, which can complete various functions such as pH measurement, temperature measurement, automatic temperature compensation, and instrument self-test;

High reliability:Highly integrated componentsWithout complex function switches and adjustment knobs;

Strong anti-interference ability: using the latest devices with impedance up to 10¹²Ω; Strong anti-interference ability for current output, enabling remote transmission. Has good electromagnetic compatibility;

Waterproof and dustproof design: protection gradeIP67， Suitable for outdoor use;

25 ℃ conversion:Pure water and ammonia added ultrapure water were testedThe conversion of the reference temperature of 25 ℃ has achieved the display of pH value at 25 ℃, which is particularly suitable for measuring weak conductivity water quality such as desalinated water in power plants or chemical plants;
