PHG-2081 Industrial Online PH Meter
As our company's latest PH analyzer, PHG-2081 Industrial online 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 or a 2-in-1 PH 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 l0 12 Ω. 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.
Communication interface: it can be easily connected to a computer to perform monitoring and communication.
Automatic temperature compensation: It performs automatic temperature compensation when the temperature is
within the range of 0~99.9ºC.
Water proof and dust-proof design: Its protection grade is IP65. It is applicable for outdoor use.
English LED display, English menu operation: It adopts menu structure, which is like that in a computer. It can
be easily operated only according to the prompts and without guidance of the operation manual.
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.
