Product Details:

Pressure Flow Velocity Measuring Instrument with a measuring range from 0-20 hPa. It is easy filter checks while inspecting differential pressure in ventilation and air conditioning systems. Measuring differential pressure aids determining if the filters are functioning properly or need to be replaced.

Pressure and Flow Velocity Measuring Instrument is ideal for carrying out pitot static tube measurements in air ducts at very high air flow speeds or when the air stream is strongly polluted. The compact, rugged meter with a measuring range from 5 to 55 m/s shows both pressure as well as air flow speed.

Features:

• 8 measurement units : psi, kPa, hPa, Pa, mm H2O, mmHg, inch H2O, inch Hg
• 2 air flow units : m/s, fpm
• Integrated density compensation
• Backlit display, min/max values, hold function
