The Yellow Jacket YJACK Charging Kit 67072 includes two YJACK wireless pressure probes (67065) and two YJACK temperature probes (67061) for instant system charge readings. The Yellow Jacket PRESS pressure gauge has a pressure measurement of up to 725 psig (50 bar) and an integrated charging port to easily adjust the refrigerant charge without removing the probes. The YJACK Wireless Temperature Clamps measures the surface temperature of pipes up to 1.25” diameter to provide accurate system temperature readings, even in difficult-to-reach places. When using the Yellow Jacket charging kit, system pressure, temperature, saturation temperature, superheat, and subcooling can be viewed, logged, and reported with the YJACK View app. The YJACK devices are the next evolution in creating an interconnected and efficient work environment allowing a service technician to work more quickly and precisely in the HVAC/R industry.
