Testo® 420 - Differential pressure gauge for 0...120 Pa

The differential pressure gauge testo 420 is suitable for precise differential pressure measurement up to 120 Pa, e.g. when checking filters on air conditioning systems. Flow velocity and volume flow are calculated by the testo 420. In addition, the measuring instrument enables absolute pressure measurement. Differential pressure meter with practical instrument functions With the aid of a pitot tube and suitable connection hoses (both optional), you can measure the flow velocity and volume flow in the ventilation duct. Time and point averaging as well as the combination of time and point averaging with simple input of the duct geometry support you when measuring in the duct. At low pressures, the automatic zero adjustment ensures higher accuracies. All measured values are easy to read on the large; illuminated display. Documentation of measurement data Measurement data can be stored in the differential pressure gauge for analysis and documentation. The management of the measurement data on the PC is very simple and without additional software. via plug & play function.
