Main highlights

•HVAC DIGITAL VACUUM GAUGE: Digital vacuum gauge can measure the real-time pressure during vacuuming of the refrigeration system, suitable for dynamic monitoring of vacuum pressure changes in HVAC and heat pump systems. It can be used in conjunction with a vacuum pump to measure the real-time pressure during vacuuming, quickly and accurately judge the degree of dehumidification and impurity removal, and detection the vacuum system and refrigeration systemin real time
•PARAMETERS: Maximum overload pressure of vacuum gauge: 72 psi/0.5 Mpa; Accuracy: 0.1-1000 Pa (digital plus or minus 5%); Resolution: 0.01(＜10 Pa); Operating temperature: -23-122 ℉; Connection:7/16 inch-20 UNF(1/4 inch SAE). Digital HVAC vacuum gauge uses pirani vacuum sensor, which can respond quickly and accurately measure micro-pressure changes in vacuum
•MONITORING MODE AND BUZZER PROMPTER: The micron vacuum gauge defaults to the normal mode after it is turned on. Press "SET" button to active target vacuum set montioring mode. After target vacuum is set, press 'SAVE CAL’ to save and active monito mode, buzzer beeps periodic. When vacuum pressure reached set pressure,alert will be activated (screeflicker,buzzer beeps), press any key to quit alert or wait 35 seconds,alewill stop automatically
•SUPPORTS 4 UNITS AND DISPLAY BACKLIT: Rogvoc digital vacuum gauge supports 4 type pressure units: Pa, mBar, mmHg, Microns. Vacuum gauge tester with a large backlit display for clear readings even in dark environments. The anti-slip rubber on both sides of the vacuum gauge and the easy-to-carry tool bag provide great convenience for work
•CUSTOMER SUPPORT: We provide 7 x 24 hours customer support. If you have any questions about the product, please feel free to contact us, we will reply within 24 hours and help you. Packing includes: digital vacuum gauge x 1, portable tool bag x 1, AA batteries x 3, extension connector x 1 and user manual

Main highlights

•1.【Digital Vacuum Gauge Pro】 Vacuum meter can accurately measure the real-time vacuum pressure within systems like HVAC and heat pumps, while also offering professional diagnostics in two modes: Evacuation Mode delivers real-time ΔT and evT data to monitor the vacuum pumping status; Pressure Leak Test Mode enables system static seal integrity validation—providing deeper insights, greater control, and unmatched efficiency in vacuum management.
•2.【Evacuation Mode】 Our micron gauge hvac in evacuation mode provides vacuum level plus critical parameters: ΔT(temp difference), evT(water vapor pressure temp), and TIME(test duration). Monitoring these values ensures air and non-condensable gases are purged. More critically, this data confirms damaging moisture has been completely removed, preventing ice blockages, corrosion, and lubricant degradation. This guarantees long-term system reliability.
•3.【Pressure Leak Test Mode】 Our digital vacuum gauge hvac, in pressure leak test mode, displays not only vacuum levels but also ΔP(pressure difference), StartP(initial pressure values), and TIME(test duration). The pressure differential(measured pressure minus initial pressure) reading provides a clear, instant indication of whether a system leak exists. This makes it an efficient, easy-to-use solution for verifying static system sealing integrity.
•4.【± 0.2% FS HIGH PRECISION】 This digital vacuum tester features a high-precision sensor, easily achieving lab-grade standards with vacuum accuracy of ± 0.2% full scale; vacuum range (Rel) 0-2000mbar; temperature accuracy of ±0.5°C (±0.9°F / ±0.5K); and vacuum resolution of 0.1 hPa, 0.1 mbar, 0.1 Torr, 0.01 inHg.
•5.【Vacuum Pressure Alerts & 3" LCD Display】 Our digital micron gauge hvac allows you to set a vacuum pressure alert value; when the measured pressure approaches this value, the screen flashes, and when the measured pressure reaches or exceeds the set point, the gauge triggers an audible alarm. Our digital vacuum gauge features a 3-inch LCD screen for crystal-clear viewing, equipped with an adjustable backlight for easy readability even in direct sunlight.
•6.【Auto Temp Compensation & Calibration】 Our vacuum gauges utilize integrated temperature sensors to automatically compensate for environmental temperature fluctuations, ensuring accurate readings regardless of ambient conditions, and feature automatic calibration that adapts to different altitudes without requiring manual recalibration.
•7.【Certified Quality & Warranty】 Rest assured, our digital micron gauges hvac meet rigorous CE, FCC, and RoHS safety certifications. Every Professional Edition gauge comes with a 3 years free maintenance—we'll replace your unit at no cost for any manufacturing defect (not caused by misuse).
