SF6 Gas Purity Detector
 
Model: JH4000CD-1
 
    
Purity of SF6 gas is not only a major item for gas quality acceptance and evaluation of equipment installation and maintenance process, but also a reliable accordance for internal troubleshooting. According to gas purity changes, it can be judged whether the equipment has any serious fault.
 
In IEC60480-2004 Guidelines for the checking and treatment of sulfur hexafluoride (SF6) take from electrical equipment and specification for its re-use, purity is listed as a detection item for SF6 fresh gas, equipment acceptance, preventive test and maintenance. SF6 purity detector JH4000CD-1 quickly and accurately detects the total amount of impurities in SF6 gas displayed in percentage. As inspected by the National Institute of Metrology, it is of excellent performance.
 
Detection Principle
 
Purity detection applies the thermal conductivity principle. SF6 purity detector JH4000CD-1 employs the most advanced thermal conductivity sensor applied in the industry currently. It is a thermal sensor with constant temperature and heat isolation. It has highly precise temperature control as well as compensation for pressure and temperature, so as to ensure excellent stability and accuracy of data detected. It is a highly precise and intelligent instrument.
