PHG-2091D Industrial Online PH Meter
PHG2091D Industrial online pH Meter is one of the intelligent online chemical analyzer of 2091 series developed
by our company. With strong environmental adaptability, clear display, simple operation and good performance
which has a high performanceprice ratio, can accurately measure the pH value of solution and temperature. It can
be widely used for continuous monitoring of pH value of solution in thermal power plants, chemical fertilizer,
metallurgy, environmental protection, pharmacy, biochemical engineering, foodstuff and running water etc.
Features
Microcomputer: It adopts high-performance CPU chip, high-precision AD conversion technology and SMT |
technology to complete the multi-parameter measurement, automatic temperature compensation and instrument |
self - checking, with high precision and good repeatability. |
Reliability: All the component are arranged on one circuit board. No complicated functional switch, adjustment |
knob and potentiometer. |
Strong interference immunity: The current output and alarm relay adopt optoelectronic isolating technology, |
strong interference immunity and the capacity of long-distance transmission. |
Automatic alarming function: Isolated alarming signal output, discretionary setting of upper and lower thresholds |
, and revocation alarm hysteresis. |
