Description
Product Overview
The Vanlison HVAC Gauge is engineered from high‑impact Acrylonitrile Butadiene Styrene (ABS) to withstand the rigors of daily shop use. Measuring 6.7 x 4.3 x 2 inches and weighing 6.3 lb, it offers a compact yet sturdy form factor. Powered by four AA batteries (included), the unit delivers dual‑side pressure readings from –101 kPa to 6000 kPa and simultaneous temperature monitoring from –40 °C to 150 °C. A pre‑loaded library of 112 refrigerants automatically displays evaporation and condensation temperatures, eliminating manual lookup errors. The backlit LCD ensures readability in low‑light environments, while 1/4″ SAE ports provide universal hose compatibility.
Usage
Designed for HVAC technicians, automotive air‑conditioning specialists, and DIY enthusiasts, this gauge excels in both residential and commercial settings. Use it to charge refrigerant, perform vacuum tests, conduct pressure leak diagnostics, or analyze system performance during routine maintenance. Its rugged ABS case resists drops and impacts on job sites, and the 10 MPa overload protection safeguards the sensor during high‑pressure events.
