1.【Digital Vacuum Gauge Pro】 - Beyond industrial-grade precision vacuum measurement, the digital vacuum gauge also features two professional diagnostic modes: Smart Evacuation Mode monitors the evacuation process, and Pressure Leak Detection Mode checks sealed systems for leaks — giving you a more professional, in-depth, and convenient way to stay on top of vacuum conditions.
2.【Evacuation Mode】 - In evacuation mode, our hvac vacuum gauge displays the vacuum level along with key parameters: temperature difference, water vapor saturation temperature, and measurement time. Monitoring these values ensures that air and non-condensable gases are completely purged. More importantly, this data confirms that damaging moisture has been thoroughly eliminated — preventing ice blockages, corrosion, and lubricant breakdown. That's how you ensure long-term system reliability.
3.【Pressure Leak Test Mode】 - In Pressure Leak Test mode, our hvac vacuum meter shows more than just the vacuum level — it also displays the pressure differential (ΔP), the initial pressure (StartP), and the test duration (TIME). The ΔP reading (P_end minus P_start) gives you an instant, clear indication of whether the system is leaking, making it an efficient and easy-to-use solution for verifying the seal integrity of static systems.
4.【± 0.2% FS HIGH PRECISION】 - Equipped with a high-precision sensor, this digital vacuum gauge easily meets lab-grade standards. Vacuum accuracy is ±0.2% of full scale, with a vacuum range (relative) of 0 to 50 mbar. Temperature accuracy is ±0.5°C (±0.9°F / ±0.5 K). Four selectable units are available — Torr, mbar, hPa, and inHg — and vacuum resolution is as fine as 0.01 hPa, 0.01 mbar, 0.01 Torr, or 0.001 inHg.
5.【Vacuum Pressure Alerts & 3" LCD Display】 - Our digital vacuum gauge lets you set a vacuum pressure alarm threshold. As the measured pressure approaches this value, the screen flashes; once it reaches or exceeds the setpoint, an audible alarm sounds. The micron gauge hvac features a 3-inch LCD screen with an adjustable backlight, delivering a clear, easy-to-read view even in direct sunlight.
6.【Auto Temp Compensation & Calibration】 - Our vacuum gauge uses a built-in temperature sensor and microprocessor to automatically compensate for ambient temperature fluctuations, delivering accurate readings in any environment. It also self-calibrates to different altitudes, so there's no need for manual recalibration.
7.【Certified Quality & Warranty】 - Rest assured, our digital vacuum gauge meets stringent CE, FCC, and RoHS safety certifications. Every Professional model is backed by a 3‑year free warranty, and if any defect occurs, we'll replace the unit at no cost to you.
