Digital Pressure Gauge, Dual Port Differential Pressure Gauge ±36.8kPa, Portable HVAC Gas Pressure Tester with 12 Units, Backlight for Air Conditioning, Ventilation Ducts

Digital pressure gauge provides instant switching between 12 measurement units (mmHg, inHg, KPa, Bar, Psi, etc.) for versatile pressure testing. Its unique "DIF" button activates the differential pressure mode with a single press, which is perfect for HVAC systems, gas appliances and industrial troubleshooting. The HD backlit display ensures clarity in low-light environments, while auto-off preserves battery life during extended downtime. Store up to 19 time-stamped readings with this precision digital pressure gauge. Ideal for laboratory testing or field diagnostics, the data retention feature allows you to track pressure trends, analyze min/max values and export recordings effortlessly. With an accuracy of ±0.3% and a fast response time of 0.1 seconds, this pressure gauge is an indispensable tool for gas engineers and maintenance professionals. Engineered with sensors and a dual-port design, this manometer delivers ±36.80KPa (±5.337Psi) measurements. It monitors pressure changes in real time, switches between average/max/min values and triggers alarms in case of overpressure or under pressure. ABS housing and auto-zero function ensure durability and error-free calibration. Simplify workflows with one-touch data queuing, screen zeroing and low battery alert. The large backlit LCD display minimizes eye strain during prolonged use, while ergonomic buttons simplify unit conversions. Designed for HVAC applications, boilers and cleanrooms, it withstands temperatures from -10°C to 60°C. From natural gas pipelines to industrial hydraulics, this digital pressure gauge tackles a variety of tasks from troubleshooting air conditioning systems, calibrating laboratory equipment or servicing wind tunnels. Its compact construction makes it a reliable partner for technicians, engineers and DIYers
