Differential pressure measurement of the cleanroom

Air flow measurements in ducts, temperature measurements in laboratories, humidity measurements in production, pressure difference measurements in clean rooms. The Testo 480 climate measurement meter with a wide range of optional probes that allows you to measure, analyse and log these and a variety of other parameters with only one device. 

• Measure multiple parameters Temperature, Humidity, Pressure Turbulence, Heat radiation, Co2 Lux, PMV/PPD, WBGT 

• Professional software for reporting & data logging 

• Highly accurate digital probes 

• Intelligent calibration concept

The testo 521-3 high-precision differential pressure measuring instrument easily determines even the smallest differential pressures (up to +2.5 hPa). Its high accuracy and a resolution of 0.1 Pa make the instrument ideal for differential pressure measurements in clean rooms or for flue inspections.
 

• Integrated temperature-compensated differential pressure sensor with accuracy of up to ± 0.5 Pa

• Calculation of the flow velocity and the volume flow via Pitot tube (optional)

• Direct zeroing of the display values of pressure probes

• 2 probe inputs for additional pressure and temperature probes
