As our company's latest PH analyzer, PHG-2081 Industrial PH Meter is a highly intelligent and English liquid crystal instrument for continuous online monitoring. It is made up of two parts: a sensor and a secondary meter. It can be used with a 3-in-1 electrode or a 2-in-1 electrode in
order to adapt various conditions.
Features
Intelligent: This industrial PH meter adopts high-precision AD conversion and single chip microcomputer processing technologies and can be used for the measurement of the PH
values and temperature, automatic temperature compensation and self-checking.
Reliability: All the components are arranged on one circuit board. No complicated functional
switch, adjusting knob or potentiometer is arranged on this instrument.
Double high impedance input: The latest components are adopted; The impedance of the
double high impedance input can reach as high as l012Ω. It has strong interference immunity.
Solution grounding: This can eliminate all the disturbance of the ground circuit.
Isolated current output: Optoelectronic isolating technology is adopted. This meter has strong interference immunity and the capacity of long-distance transmission.
Multi-parameter display: The PH values, input mV values (or output current values), temperature, time and status can be displayed on the screen at the same time.
