Engineered for the professional HVAC technician, this series of refrigeration gauges provides the accuracy and durability needed for servicing a wide range of AC systems. With clear scales for the most common refrigerants—R-410A, R-22, R-404A, and R-134a—these tools are versatile and essential additions to any toolkit. Each gauge features a large, easy-to-read 3-1/8” dial housed in a rugged steel case with a shatter-resistant polycarbonate lens. Inside, the precision copper movement delivers Class 1.6 accuracy, ensuring you get reliable readings you can trust.

Designed for demanding field use, a flutter-free pointer resists vibration for stable measurements, while an external adjustment screw allows for quick on-the-fly calibration. Whether you are equipping your workshop with a complete 2-way manifold set or need a reliable single gauge for a specific task, each unit comes complete with a 12-inch, 800 PSI rated service hose with standard 1/4" SAE fittings, making it ready for the job right out of the box.
