PHG-2081 Industrial PH Meter
PHG-2081
Industrial 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 of
|
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.
|
|
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 0~99.9℃.
|
|
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.
