Digital Manometer Dual Port Air Gas Pressure Tester Differential Pressure Gauge with LCD Backlight Display, Battery or USB Cable Powered, Supports Temperature Measurement ℃/ ℉

OverviewThis instrument is a professional high precision, high range, high resolution, large screen display pressure sensor, and is designed with high precision ADC and low power MCU. This digital differential pressure gauge can also be used for temperature measurement, and it supports ℃/ ℉ switchable. One machine in hand, worry-free using in multiple scenes. Features: LCD Backlight Screen, Unit Switchable -- High resolution digital LCD display with green backlight, easy to read no matter in the day or at night, clear at a glance. We provide 2 models for your option, whose measurement units are of different ranges and resolutions. Dual Channel Pressure Gauge -- Quickly measure the pre-blue detection pressure value (relative to the current atmospheric pressure). Dual channel can simultaneously detect the pressure difference between two detection ports. Temperature Measurement & Other Functions -- This digital differential pressure gauge can also be used for temperature measurement, and it supports ℃/ ℉ switchable. Data hold/ data storage (100 groups)/ data search function, maximum/ minimum data mode. Dual Power Supply Method -- Powered by 9V battery (not included) or external USB cable. Low power MCU designed. Automatically shut down after 15 minutes idle time to save power. 6.8V low battery indicator for convenient use. Scope of Application -- Widely used in natural gas pipelines, air-conditioning refrigeration and ventilation systems, mechanical hydraulics, plastic molding, ceramic products, biopharmaceutical molding, mining area pressure detection, petrochemical refining, gas, liquid, and production industrial equipment pressure detection. Note: 1. Color and size may be slightly different due to manual measurement and different light conditions. Thanks for understanding. 2. Please read the user manual carefully before use.
