  • Welcome to the future of charging
Style: Temperature Kit
I'm a 80 year old retired AC&R tech. Back in the day, we hardly even knew what superheat and subcooling even meant. Now days it is an essential part of servicing. The typical charging method of charging a vehicle was to remove all refrigerant, weigh it and recharge with spec. amount. I was able to charge my Odyssey by adjusting the subcooling and superheat as I charged it. When I felt the reading were in the zone, I was then able to close the hood and drive it around, while checking the readings. This tool is tough enough for day to day usage with the info needed for the modern tech. ... show more

  • Compact
Style: Temperature Kit
This manifold is great, no more having to eyeball the PSI on the gauges or use multiple apps for getting subcool & superheat. I did buy 2 of the Testo 605i probes for getting my target superheat calculated. One more thing, it's great to watch from the 1st floor as a condenser unit that you just installed gets turned on for the first time ... show more
