Refrigeration system maintenance - Velocity measurement

Use the 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.

• 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

• Save measurement data for analysis and documentation
