Overview
PHG-2081D multi channel industrial online PH Meter has the characteristics of complete English display, English menu operation, intelligent, multi-function, high measuring performance, strong environment adaptability, it can accurately measure PH value and temperature of the solution. It can be widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmacy manufacturing, biochemistry, foodstuff and running water etc solution pH value of continuous monitoring You can choose between two to four channels, now the pHG-2081D multi-channel online pH meter is equivalent to the previous two to four pH meter, most can connected with four pH electrode at the same time. You can choose between two to four channels, now the pHG-2081D multi-channel online pH meter is equivalent to the previous two to four pH meter, most can connected with four pH electrode at the same time.
Features
It can arbitrarily chosen dual channel to four channel pH meter. All the channels are mutually independent, non interfering, and most can be connected with four electrode pH at the same time. It is English LCD display, English menu operation.
|
Microcomputer: It adopts high-performance CPU chip, high-precision AD conversion technology and SMT
|
|
technology to complete the multi-parameter measurement, temperature compensation and instrument
|
|
self-checking, with high precision and good repeatability.
|
|
25℃ Conversion: Nernst electrode slope temperature compensation, pure water and ultra-pure water with
|
|
addition of ammonia converted at 25℃.
|
|
Double high impedance input circuit: Low pH electrode resistance, the instrument has good stability, fast
|
|
response, strong anti-interference .
|
|
Solution grounding: This can eliminate all the disturbance of the ground circuit.
