When the SF6 gas moisture tester is not used for a long time, there will be some air left in the test pipe and air chamber. Therefore, in the first test, the high humidity gas in it will affect its test speed, because the tested SF6 The moisture in the air needs to be taken away before the gas reaches saturation. So we will find that when testing the second SF6 electrical equipment and the measurement speed will be very fast (3-5 minutes).
If you need to make a measurement in high temperature weather, we recommend that you try to arrange the measurement time in the morning when the temperature is low, because the higher temperature will affect the accuracy of the measurement.
Reference Standard: Electric Power Industry Standard DL/T506-2007 "Method for Measuring Humidity of Insulating Gas in Electrical Equipment of Sulfur Hexafluoride"
Requirements for measuring ambient temperature and humidity
Ambient temperature: 5℃～35℃ (as far as possible to measure between 10℃～30℃)
Technical characteristics
(1) Portable design: The instrument is lighter, easy to carry and use.
(2) Quick measurement: No need to wait after the instrument is turned on, measure immediately and get the humidity value quickly.
(3) Fast gas saving: The gas consumption is only about 2L (101.2kPa) during measurement.
(4) Self-locking joint: The self-locking joint imported from Germany is adopted, which is safe and reliable without air leakage.
(5) Data storage: It adopts large-capacity design and can store up to 50 sets of test data.
(6) Clear display: The LCD screen directly displays the dew point, micro water (ppm), ambient temperature, ambient humidity, time and date, battery power, etc.
(7) Built-in power supply: Built-in 4Ah rechargeable lithium battery, which can work continuously for 10 hours after a full charge.
