Product Description

PHG-2091 Industrial PH Meter



PHG-2091 industrial online PH meter is precision meter 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

LCD display, high-performance CPU chip, high-precision AD conversion technology and SMT chip technology,

Multi-parameter, temperature compensation, high precision and repeatability

US TI chips; 96 x 96 world-class shell; world-famous brands for 90% parts

The current output and alarm relay adopt optoelectronic isolating technology, strong interference immunity and

the capacity of long-distance transmission.

Isolated alarming signal output, discretionary setting of upper and lower thresholds for alarming, and lagged

cancellation of alarming.

High-performance operational amplifier, low temperature drift; high stability and accuracy.
