It's been estimated that one in 10 vehicles on the road has an A/C system with contaminated refrigerant. The only way to know for sure if you can safely recover these charges is with a refrigerant identifier. You may also save hundreds of dollars by checking bulk tanks for purity before use.

Robinair's new Cool-Tech line shows you in just seconds if it's safe to recover or recharge the refrigerant. There's no guesswork because a red light indicates "fail" while a green light is your signal to continue with service. For R-12 and R-134a vehicles.
 
 
  Fast and Accurate
    Displays test results in less than a minute and passes the refrigerant only if it's 98% pure. To ensure consistent, rapid results, the units are not pressure/temperature dependent.
     
     
  Reliable Technology
    The instruments use dependable infrared technology developed by Neutronics, Inc., to determine if the refrigerant is an acceptable type and is pure enough to be used.
     
     
  Unique Case Design
    Put all the components up front where you can see them at a glance, including the filter. Contoured case can be held in either hand and rubber feet protect the vehicle's finish.
