PHG-2081D Multi Channel Industrial PH Meter
PHG-2081D Multi
Channel Industrial PH Meter
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 of
this model PHG-2081D Multi Channel Industrial PH Meter 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.
