Handheld Manometer with Backlit, Dual-Port HVAC Digital Manometer Gas Pressure Tester, LCD Screen & Indoor Temperature Measurement, 12 Units, for Natural Gas Pipelines Ventilation Detection

Versatile Functionality, Offers 12 selectable units of measure (mmHg, inHg, ftH₂O, cmH₂O, inH₂O, Pa, KPa, mbar, bar, psi, Kgcm², and ozin²). Comes with features like data hold, max/min value recording, low power indication, and auto power off (can be disabled). The DIF key allows for obtaining the differential pressure between positive and negative pressure, and the built-in temperature sensor measures current temperature.
High Precision Measurement, Equipped with advanced German-made sensors for exceptional accuracy and durability. With a measuring range of ±20.68 kPa / ±2.999 psi and an accuracy of ±0.18% FSO at 25°C, it ensures precise measurement of air pressure and differential pressure.
User-Friendly Design, Comes with two 25 cm-long hoses and a metal thread for easy pressure testing between two gas containers. The large LCD with backlight makes data easy to read even at night. The bezel design is ergonomic and anti-slip for a better grip.
Powerful Data Recording, Can store 100 groups of data and display the maximum and minimum readings during a recording period. The DIF function shows the differential value of two tested gases, facilitating data analysis and comparison.
Wide Application and Excellent After-Sales Service, Suitable for gas measurement and calibration, troubleshooting gas pressure systems, laboratory testing, and maintenance and installation of various gas appliances like blowers, clean rooms, and boilers.
