The Fieldpiece SC57 Clamp Meter is simply the best HVACR clamp meter on the market. The Fieldpiece SC/57 provides fast and accurate readings for all the measurements HVACR techs take everyday, plus it's wireless. It's the only clamp meter on the market that can take true wireless readings; And with the Fieldpiece SC-57 Wireless Swivel Head Clamp Meter, techs can do a faster more accurate job. There are countless ways wireless measurements can help HVACR techs do a better job, but there are two main issues solved by taking measurements wirelessly.

Less time & hassle
A large part of a techs day is spent walking back and forth between measurement points, and adjustment points. With the Fieldpiece SC57 wireless clamp meter, techs can wirelessly send measurement readings directly to the meter at the adjustment point. So things like indoor wet bulb can be read while techs are at the condenser making adjustments.

Better accuracy
Wireless measurements give HVACR pros a real-time snapshot of the system, so measurements are taken under the exact same conditions. So temperatures and pressures don't have time to change between different readings. The Fieldpiece SC57's real-time measurements allow techs to accurately install, service, and charge systems.
