Detailed introduction:

PHG-2091A Industrial PH Meter

●Overview

The pHG-2091A industrial PH meter is one of the 2091 series intelligent online chemical analyzers developed by our company. It has strong environmental adaptability, clear display, simple operation excellent test performance. It has a high cost performance can accurately measure PH value temperature of the solution. It can be widely used for continuous monitoring of PH value in solutions such as thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food tap water.

●Features

● Microcomputerization: High-performance CPU chip, high-precision AD conversion technology SMT chip technology are used to complete multi-parameter measurement, automatic temperature compensation, instrument self-test, high precision good repeatability

● High reliability: single board structure, only one circuit board, no complicated function switch, adjustment knob potentiometer

● Strong anti-interference ability: The current output alarm relay adopt photoelectric coupling isolation technology, which has strong anti-interference ability realizes remote transmission

● Automatic alarm function: The alarm signal is isolated, the upper lower alarm limits can be set arbitrarily, the alarm lag is cancelled
