Precision you can trust

Accurate readings matter when diagnosing and servicing refrigerant systems. The gauges feature five scales on each dial with a stated accuracy of ±1.6%, and a dry dial design helps keep readings stable in cooler environments. A dedicated calibration screw supports repeatable measurements over time, so you can rely on consistent results across jobs.

• 5-scale, high- and low-side gauges with ±1.6% accuracy
• Dry dial design for stable readings in cold conditions
• Calibration screw for repeatable measurements

Safe, durable operation

The aluminum 3-way manifold includes an unloading valve for controlled pressure relief during service. Reinforced brass fittings and updated gauge protectors help maintain a reliable seal with A2L-compatible systems, while the robust construction resists wear during regular use.
