DDG-208
Industrial Conductivity Meter
the Industrial Conductivity Meter is With strong environmental adaptability, clear display, easy
operation and excellent measuring performance, the DDG-208 Intelligent On-line
Conductivity Meter has very high performance-price ratio. It can be widely used
for continuous monitoring of the conductivity values of the solutions used in
the following industries: thermal power plants, chemical industry, chemical
fertilizer, metallurgy, environmental protection, pharmacy manufacturing,
biochemistry, foodstuff and running water.
Features of
|
Fully intelligent: Industrial Conductivity Meter adopts
high-precision AD conversion and single chip microcomputer processing
technologies
|
|
and can be used for
conductivity and temperature measurement, automatic temperature compensation,
automatic
|
|
range switching,
self-checking, etc.
|
|
Multi-parameter display: The
conductivity and temperature values can be displayed on the same screen at
the
|
|
same time. It adopts LED
display module with high brightness. the displayed values can be seen from
|
|
along distance away.
|
|
Strong
interference immunity: Its current output adopts optoelectronic isolating
technology. This meter has
|
|
stronginterference
immunity and the capacity of long-distance transmissionas well as excellent
electromagnetic
|
|
compatibility.
|
|
25℃ Conversion: The conductivity value measured at the current
temperature is converted to that at 25℃;
|
|
thus, this
conductivity meter always displays the conductivity value at 25℃. Therefore, this meter is especially
|
|
suitable for testing
the various water solutions in power plants.
