Overview

The D485 multi-function handheld digital pressure gauge is suitable for measurement and on-site calibration of ventilation and air conditioning systems, clean rooms, or troubleshooting of any gas pressure systems. This handheld instrument can measure differential pressure of air and non-corrosive gases. With simple operation and clear readings, it is an indispensable testing tool for HVAC technicians, operation and maintenance engineers, and scientific researchers. When used in conjunction with the pitot tube produced by Dewey, it can be used for wind speed measurement. A standard 9V battery can provide 100 hours of normal operation. Metric or imperial units can be selected via a button switch. The large LCD display facilitates easy reading. The pressure sensor adopts a high-stability differential pressure sensor. The standard 1/8" tower connector can be connected to plastic or rubber tubing for pressure guiding. The instruction manual is printed on the back of the instrument.
