Testo 420 Differential Pressure Measuring Instrument

The Testo 420 Differential Pressure Measuring Instrument can be used to measure differential and absolute pressure up to 120Pa. Using a compatible connection hose alongside a pivot tube, users are able to measure flow velocity and volume flow in ventilation ducts. The Test 420 is highly accurate for low pressures thanks to the automatic zeroing process.

Timed and multi-point mean calculation, as well as a combination of the two, allow for support for measurements in ducts thanks to the simple input of the duct geometry. The large backlit display allows measurement data and calculations to be viewed clearly.

Measurements and calculations can be stored on the Test 420's 2GB internal memory for analysis and documentation. Data can be easily transferred and managed on a PC without any additional software, thanks to the plug and play function of the Testo 420.
