PHG-206
Industrial PH Meter
PHG-206 Industrial online PH Meter is one of the intelligent
on-line chemical analyzers developed by our company. With strong environmental
adaptability, clear display, easy operation and excellent measuring
performance, it has very high performance-price ratio and can precision
measuring the PH and temperature values of the solutions. It can be widely used
in the following industries: thermal power plants, chemical industry, chemical
fertilizer, metallurgy, environmental protection, pharmacy manufacturing,
biochemistry, food and running water etc.
Features of
|
Intelligent: This intelligent
online PH meter adopts high-accuracy AD conversion and single chip
microcomputer
|
|
processing technologies and can
be used for measuring the PH values and temperature. This meter has many
|
|
functions such as
automatic temperature compensation and self-checking.
|
|
Strong interference immunity:
It adopts the latest components and high-impedance input of l012Ω.
Its current
|
|
output adopts optoelectronic
isolating technology. This meter has strong interference immunity and the
capacity
|
|
of long-distance
transmission as well as excellent electromagnetic compatibility.
|
|
High protection grade: It
adopts waterproof and dust-proof design and is applicable for outdoor use.
(With a
|
|
protection grade of
IP65)
|
|
25℃ Conversion: For
pure water and ultrapure water added with ammonia, the PH value measured at a
|
|
temperature other
than 25℃ is converted to that at 25℃, which is regarded as the reference
temperature;
|
|
thus, this PH meter
always displays the PH values at 25℃. Therefore, this meter is especially
suitable for testing
|
|
the various water
solutions in power plants.
|
|
Multi-parameter
display: The PH and temperature values can be displayed on the screen at the
same time. It
|
|
adopts LED display module with
high brightness. The main display can show the pH values with red 10 x 10mm
|
|
Nixie tubes. As red display is
eye-catching, the displayed values can be seen from a long distance away.
