Product Description DDG-3080B online Conductivity Temperature Analyzer Meter Features: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.High Reliability: All the components are arranged on one circuit board. No complicated functional switch, adjusting knob or potentiometer arranged on this instrument.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.Water proof and dust-proof design:Its protection grade is IP65. It is applicable for outdoor use. 25oC Conversion: The conductivity value measured at the current temperature is converted to that at 25oC;thus, this conductivity meter always displays the conductivity value at 25oC. Therefore, this meter is especially suitable for testing the various water solutions in power plants. Automatic range switching: The measuring ranges can automatically switch within the measuring range of the electrode.Communication interface: RS485, It can be easily connected to a computer to perform monitoring and communication Phase sensitive detection: Eliminating the influence of conductors on the measurement of conductivityTechnical Indexes1.
