"The most comprehensive source for Automotive Tools & Equipment" Refrigerant Identifiers... Critical for Today's Automotive A/C Service It's been estimated that one in 10 vehicles on the road has an A/C system with contaminated refrigerant.

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 signals to continue with service. For R-12 and R-134a vehicles.
