【High-Precision & Wide-Range Professional Digital Vacuum Gauge】This vacuum gauge features a high-accuracy sensor with ±0.2% FS vacuum precision. Measuring range: 0~200,000Pa (0-2000mbar, 0~1500Torr), with 4 selectable units: hPa, mbar, Torr, and inHg. Temperature range: -55~125°C (-67~257°F). The vacuum gauge HVAC precisely detects minute pressure variations and is widely used in scenarios such as automotive AC maintenance, household AC maintenance, refrigerator repairs, and refrigeration systems. With stable readings and fast response time, it's the ideal tool for automotive repair and HVAC maintenance.
【Temperature Compensation & Auto-Calibration】Temperature compensation enables the sensor to obtain accurate readings under different temperature conditions. The automatic calibration function, based on standard atmospheric pressure, can automatically adjust the absolute pressure value according to different altitudes, ensuring more accurate measurements. You can complete your work normally under various complex environmental conditions.
【Buzzer Alarm & Multi-Unit Conversion】When the measured pressure approaches the maximum target pressure value, the data flashes. If the pressure exceeds the maximum target pressure value, an audible buzzer alarm is triggered— no need for constant screen monitoring and effectively preventing system overpressure. The system supports 4 pressure units (hPa, mbar, Torr, inHg) and 3 temperature units (°C, °F, K) for instant switching with a single button, removing the hassle of manual conversions.
【Vacuum Evacuation Mode & Pressure Leak Test】This vacuum gauge features both vacuum evacuation mode and pressure leak test functions, where the evacuation mode effectively removes various gases and moisture from air conditioning pipelines to ensure system cleanliness while utilizing temperature variations to verify thorough vacuuming, and the pressure leak test checks for potential refrigerant leaks in cooling systems, providing reliable support for your HVAC maintenance.
【Large Backlit LCD HD Display & Auto Shutdown】This vacuum gauge HVAC features a high-definition LCD digital display. The backlight mode can be activated anytime, making it suitable for various lighting conditions - whether in bright outdoor sunlight or dim indoor environments, ensuring clear data visibility for easy task completion. The HVAC vacuum gauge automatically turns off the backlight after 5 minutes of inactivity and shuts down completely after 30 minutes to conserve battery power.
【 Foldable Hook & Anti-Slip Silicone & 1/4" SAE Standard Interface】This HVAC pressure gauge features a foldable hook to reduce manual holding during operation, effectively reducing fatigue during prolonged use. The HVAC pressure gauge body is wrapped with anti-slip silicone on both sides for a secure grip and comfortable handling. Equipped with a 1/4" SAE standard interface, it enables quick and easy connections, helping you complete tasks efficiently and effortlessly.
【 Easy To Use & Packaging List】This HVAC vacuum gauge is designed for effortless operation. (In Vacuum Mode, simply set your desired target pressure and maximum target pressure values for vacuuming operation.) Set temperature and pressure units according to your requirements, then start the test with the option to pause or retest as needed. The package includes: 1 digital vacuum gauge main unit, 1 tee joint, 1 hose (randomly supplied in red or yellow), 4 AAA batteries, 1 user manual, and 1 box.
【Use with Confidence & 3 Years Warranty】Our vacuum gauge is FCC, RoHS, and CE certified, you can use it with confidence. We promise 3-year after-sales service and 7 x 24 hour customer service to ensure your shopping experience. If you encounter any problems during use, please do not hesitate to tell us.
