Khq8500 type insulating oil gas content automatic tester

(developed according to the latest national standards)

Applicable standard: DL / T 423-2009



Instrument characteristics



◆ patented sample quantitative calibration system: introduce a certain amount of oil sample (about 50ml) into the degassing system for degassing.



Special degassing system: vacuum pressure spray, automatic constant temperature control, high degassing efficiency.



◆ high precision data detection and processing system: the high precision and high stability differential pressure sensor at the inlet is used to collect the differential pressure signal generated between the internal pressure of degassing tank after degassing and the pressure before entering the oil, which is amplified and processed by the data processing system, and then the calculated volume percentage of air content in the oil is directly displayed on the display screen. Make the test data more accurate and repeatable.



◆ international leading waste oil collection system: collect the cleaning liquid and test oil samples entering the instrument and discharge them automatically after each test.



◆ the sensor for atmospheric pressure measurement and ambient temperature can automatically measure your ambient temperature and atmospheric pressure whenever and wherever you are, automatically convert to the air content at 0 ℃ under standard atmospheric pressure, and display directly on the LCD screen, making your work easier.



◆ the unique gas injection reverse standard test procedure can let you easily test whether the instrument calibration or measurement is correct.



◆ the instrument can automatically store the test results, and at the same time store the time, temperature, atmospheric pressure, etc. during the test, so that you can easily access the data.



◆ friendly interface display system: TFT real color LCD screen imitates windows interface display, Chinese menu touch operation, intuitive and friendly, simple and convenient.
