5.LCD display to indicate dew point, PPM, temperature, humidity, date, battery etc

6.Built in 4Ah lithium rechargeable battery, one time use lasts for 10 hours under full charge

Measurement method

1.connect SF6 equipment

First of all, find the joint from the accessories of the instrument which suitable to the SF6 electrical equipment ,connects the end of the pipe to the attachment joint and the wrench, and then inserts the fast joint on the test tube into the sampling port on the instrument and connects the exhaust pipe to the air outlet.

4.Start to measurement

First, open the flow valve on the panel to regulate the flow rate, adjust the flow to about 0.5L/min, and start to measure the SF6 dew point. The first equipment takes 5~10 minutes to measure, and then each equipment takes 3~5 minutes.

5.Instore data

After measurement is completed, click the "equipment number" to change the number, click "save" and save the data in the instrument.
