Trace Moisture Analyzer DR2135
Using the Karl Fischer coulometric method, it is a reliable method to determine trace moisture in different substances. This trace moisture analyzer successfully applies this method and adopts microcomputer control. It features fast analysis speed, high precision, Chinese LCD display, automatic printing, dual CPU design, automatic current deduction function, and self-diagnosis of instrument faults, menu selection, etc., to achieve better operation and use. It is an easy-to-operate, fully automatic analytical instrument. It is an ideal instrument for moisture analysis of insulating oil.

Trace Moisture Analyzer DR2135
1. Connect SF6 equipment
Connect the threaded end of the measuring pipeline to the switch connector and tighten with a wrench. Close the needle valve at the other end of the measuring pipeline.
Then insert the quick connector end of the test pipeline into the sampling port of the moisture analyzer, and connect the exhaust pipeline to the gas outlet.
Finally, connect the switch connector to the measurement interface of the SF6 electrical equipment and tighten with a wrench.
2. Check battery level
This instrument recommends using AC power first.
When using DC power, check the battery level displayed in the upper right corner. If the battery level is below about 20%, turn off the device and charge it before continuing use.
3. Start measurement
First, fully open the needle valve on the measuring pipeline, then use the flow control valve on the panel to adjust the flow rate to about 0.5L/M, and start measuring the SF6 dew point.
The measurement time for the equipment is 5-10 minutes, and then 3-5 minutes for each subsequent device.
4. Store data
After the measurement is completed, the data can be stored in the instrument. Press the "OK" key to bring up the operation menu. The specific operation method is described in the next section.
5. Measure other equipment
After measuring one device, close the needle valve on the measuring pipeline and the regulating valve on the moisture analyzer. Remove the adapter from the SF6 electrical equipment. If you need to continue measuring other devices, follow the above steps to measure the next device.
6. End measurement
After all measurements are completed, turn off the power of the moisture analyzer.
