Wireless high-pressure gauge Smart Probe that streams refrigerant pressure to measureQuick over Bluetooth for automated superheat and subcooling.
The testo 549i is a wireless high-pressure gauge Smart Probe for refrigeration and air conditioning service. It threads onto a service port to read refrigerant pressure from -15 to 870 psi at plus or minus 0.5 percent full-scale accuracy and streams the reading to a phone or tablet over Bluetooth with a 350-foot wireless range and 150-hour battery life. As part of the Testo Smart Probes ecosystem it feeds measureQuick directly for automated superheat and subcooling calculations.
