Ritchie Engineering has developed a refrigerant gauge set to measure some common retrofit refrigerants. Since each HFC refrigerant is pressurized differently, accurately monitoring these new refrigerants has become extremely difficult. Thus, the company is offering a set of large 3-1/8-inch red and blue dry manifold gauges specifically calibrated for monitoring these refrigerant alternatives. These 1-percent accuracy (Class 1) gauges with front recalibrating screw are available individually or on the Yellow Jacket Titan™ 4-Valve Test and Charging Manifold.
