Product Introduction
MOEORW-WQZ41 The SF6 gas decomposition product detector is specifically designed for testing the insulating gas properties of SF6 in electrical equipment. It is a modularly designed testing device; with the appropriate testing modules, it can be used to determine the decomposition products of SF6 gas. The instrument employs a combination of anti-cross-interference design, a pump-pressurized gas chamber sample gas purging system , dynamic temperature correction compensation technology, and error correction technology for different types of carrier gases to ensure testing accuracy. SF6 gas is introduced into the sensor at a specific flow rate, and the instrument directly measures the content of the main decomposition products of SF6 gas .
After the instrument completes its power-on self-test, the user can connect it to the device under test and adjust the gas inlet flow rate to directly obtain accurate SF6 gas decomposition product content. All test data will be stored in the instrument's memory and can also be uploaded to a computer after the test is completed.

Product features and applications
SF6 gas decomposition product detection module
Dynamic temperature correction and compensation technology
Variations in sample gas temperature and ambient temperature can affect the characteristics (baseline and range) of the electrochemical sensor, thus impacting measurement accuracy. This device incorporates a built-in sensor temperature characteristic curve and acquires sample gas and ambient temperatures in real time via an independent temperature measurement circuit. The measurement results are dynamically corrected based on the sensor temperature characteristic curve to ensure accurate and reliable measurements.
Anti-cross interference design
When using multiple electrochemical sensors to simultaneously measure a mixture of various target gases, cross-interference with a particular gas by one sensor can affect detection accuracy. A built-in specific chemical filter removes interfering gases before they reach the sensing electrodes of the electrochemical sensor, thus reducing interference from specific gases.
Pump-type gas chamber sample gas removal system
Gas measurement chambers typically employ a tubular structure design. Because the pressure inside and outside the chamber is the same, the discharge of sample gas from the chamber relies on the natural permeation between the sample gas and the outside air. This results in slow and incomplete removal of residual sample gas, affecting the accuracy of subsequent measurements. Furthermore, residual sample gas in the chamber shortens the sensor's lifespan. To address this, after each measurement, a pump can be used to draw outside air into the device. This air is then filtered, dried, and introduced into the chamber, creating a pressure difference that expels the sample gas from the chamber. This ensures no sample gas residue remains, maximizing measurement accuracy and extending the sensor's lifespan.
