DDG-3080B Industrial Conductivity Meter
DDG-3080B Industrial
Conductivity Meter
Features of
u Intelligent: This Industrial Conductivity meter adopts
high-precision AD conversion and single chip microcomputer processing
technologies and can be used for the measurement of the conductivity values and
temperature, automatic temperature compensation and self-checking.
u High Reliability: All the components are arranged on one circuit
board. No complicated functional switch, adjusting knob or potentiometer
arranged on this instrument.
u Strong interference
immunity: 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.
u Water proof and dust-proof design: Its protection grade is IP65. It
is applicable for outdoor use.
u 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.
u Automatic range
switching: The measuring ranges can automatically switch within the measuring
range of the electrode.
u Communication
interface: RS485, It can be easily connected to a computer to perform
monitoring and communication
u Phase sensitive
detection: Eliminating the influence of conductors on the measurement of
conductivity.
