• 【Wide Application】CMTOOL Digital vacuum gauges are ideal for monitoring vacuum and pressure variations in HVAC, air conditioning, refrigeration, and heat pump systems. These HVAC vacuum gauges are widely applied in the automotive, pharmaceutical, laboratory, industrial manufacturing, chemical, and food processing industries. A digital vacuum tester is an indispensable instrument for HVAC technicians, automotive professionals, laboratory researchers, and related technical personnel.
• 【±0.2% FS High Precision & 4 unit Display】This digital vacuum tester is equipped with a high-precision sensor offering ±0.2% FS vacuum accuracy, reaching laboratory-grade performance. It supports 4 pressure units (mbar, hPa, Torr, inHg) and 3 temperature units (°C, °F, K), with clear, direct readings requiring no conversion. The 3-inch backlit LCD screen ensures excellent visibility in both bright sunlight and dim environments.
• 【Pressure Leak Test Mode】Our digital HVAC vacuum gauge features a dedicated pressure leak test mode that simultaneously displays vacuum level, ΔP (pressure difference), StartP (initial pressure), and test duration. By calculating the difference between real-time pressure and the initial pressure value, the gauge provides a clear, instant indication of potential system leaks. This delivers an efficient and user-friendly solution for verifying the static sealing integrity of refrigeration and HVAC systems.
