Neutronics offers their QuickDetect A/C Sealant Detection Kit for protecting refrigerant identifiers and recovery machines from potential sealant damage. Features include:
Compatibility with both R134a and R12 systems.
When connected to the A/C system, Quick Detect is designed to mimic a leak. So if a sealant is present in the system it will solidify in the disposable test cartridge, and cause the flow meter to show "no flow".
The kit comes with 10 test cartridges, R134a and R12 couplers, a test hose, a flow meter, a syringe and detailed instructions in a molded carrying case.
Replacement cartridges are available separately in packages of 25.
