Features All tests contain halogen refrigerants. Use high quality sensors, high working sensitivity, long life expectancy. This detector is a start reset and automatic follow function, which can ignore the level of concentration of halogen gases in the environment. Adjust sensitivity, all instruments can automatically adapt to the best detection status; Built-in voltage, high accuracy and the use of ultra-low power IC design make the work more stable. Can be used in car air conditioning system. Features:Adjust sensitivity, all instruments can be automatically adjusted to the best detection state; Built-in voltage, high precision and using ultra-low power IC design, the work is more stableThis detector is a start reset and automatic follow function, can ignore the concentration level of halogen gases in the environmentApplicable scope: not only can be used in car air conditioning system, can be used even in: (1) even in: It can detect air conditioning, refrigeration system and coolant recovery device. Instrument for all halogen gases (including chlorine and fluoride) has answer, but not yet limited to these: E.G.R 12, R11 CFC, R503 R500, etc...E.G.R HCFCs R123, 22, R124, R114 etc...E.G.R 134a Nathan Road, R124, R114 etc...E.G.R 134a Nathan Road, R404a HCFC and R125 etc... It is still capable of detecting other compounds, such as AZ-50, HP62, MP39, etc...(2) the detection of ethylene oxide on the gas escape hole of the equipment (halogen thruster detection);(3) the SF high voltage switch that detects 6;(4) detection of most fluorine, chloride, bromine ReReReReReReRe(5) Detection extinguishing systems, dragon gas. Package includes: 1 x HFC Gas CFC Refrigerant Leak Detector Note: Please note that the new type and old type of this product will be sent randomly and make sure you do not mind before ordering.
