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
Fully intelligent: It 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. |
