TESTO 420

0560 0420 is a testo 420 differential pressure measuring instrument to carry out simple, efficient tests on filters. You can also use the measuring instrument in conjunction with a Pitot tube to measure flow velocity and volume flow really easily in ventilation ducts. It is suitable for accurate differential pressure measurement up to 120Pa, e.g. when checking filters in HVAC systems. Flow velocity and volume flow are calculated by the testo 420. The measuring instrument can also be used for absolute pressure measurement.

• Differential pressure measurement, e.g. to check filters in air conditioning and ventilation systems
• Calculate flow velocity and volume flow using a Pitot tube
• Handy instrument featuring a large display and user-friendly menu guidance
