Industrial pH Meter for Water (PHG-2091)

Product Description

Description
PHG-2091 industrial online pH meter is precision meters for measurement of pH value of solution. With
complete functions, stable performance, simple operation and other advantages, they are optimal instruments
for industrial measurement and control of pH value. Various pH electrodes can be used in PHG-2091
industrial online pH meter.

Features
1. LCD display, high-performance CPU chip, high-precision AD conversion technology and SMT
Chip technology, Multi-parameter, temperature compensation, high precision and repeatability
2. US T1 chips; 96 X 96 world-class shell; World-famous brands for 90% parts
3. Current output and alarming relay are isolated and protected by photocoupler, providing high
Interference immunity and long-distance transmission.
4. Isolated alarming signal output, discretionary setting of upper and lower thresholds for alarming,
and lagged cancellation of alarming.
5. High-performance operational amplifier; Low temperature drift; High stability and accuracy.
