Product Details
✓Upgraded Digital Vacuum Gauge: Includes 1 digital vacuum gauge, 1 1/4" SAE extension connector fitting, 1 T-connector, 1 handy handbag, and 1 instruction manual. It is perfectly suitable for your measurement work and applicable to HVAC systems
✓Wide Measurement Range & High Accuracy: Our digital vacuum gauges can achieve a range of 0-75,000 microns (mmHg) with ±5% accuracy. It is an ideal tool for micro-leakage detection and vacuum quality assessment in HVAC/R systems, with a resolution of 1 micron at the critical 30,000 microns
✓Rugged HVAC-Optimized Build: 14 PSI overvoltage protection, 1/4-inch SAE bell mouth (7/16-20 UNF), compatible with HVAC industry tools, suitable for 32-122°F (0-50°C) environments. Freely switch between Pa/mBar/mmHg/Micron units to meet global standards and diverse scenario requirements
✓Pro-Grade Dual Calibration: Supports full-scale and zero-point calibration to achieve lasting accuracy. Full-scale calibration: Press and hold SAVE/CAL for 3 seconds at atmospheric pressure until a "--- "appears. Zero-point calibration: When the vacuum degree reaches 0.1Pa, press "SAVE/CAL" until "0.1Pa" is displayed
✓Real-Time Monitoring & Alerts：A large LCD display with backlight and fast refresh function provides real-time digital readings at a refresh rate of 0.5 seconds, remaining clearly visible even in dim environments. The vacuum threshold can be customized. When it does not meet the standard, an audible and visual alarm will be automatically triggered
✓Intelligent Energy-Saving Design: Backlight mode 20 automatically turns off, and the device automatically shuts down after 10 minutes of inactivity, extending battery life. Note: Only applicable to atmospheric environment. Do not use refrigerants or reactive gases. After use, tighten the copper cap and store in a dry place
✓Easy to Clean: During operation, the sensor may be interfered with by foreign objects. Remove the battery and turn off the machine, gently shake to remove the foreign objects, rinse with alcohol, tighten the copper cover for sealing and protection, and repeat the rinsing 3 to 4 times. The air-drying time should be ≥2 hours. Goggles/gloves must be worn during operation
✓Perfectly Matched Measurement Kit: The digital vacuum gauge, paired with a 1/4-inch SAE extension hose and T-joint adapter, delivers precise vacuum readings. Should any issues arise, our professionals stand ready to assist you 24 hours a day
