testo 510 Pressure Meter Differential

The Testo 510 differential pressure meter allows you to carry out pressure difference measurements in air condtioning systems or air flow measurements in ventilation ducts using a pitot tube. The trusty and reliable meter has been tried and tested in the field and is ideal for installation and maintenance work in and around ventilation and air conditioning.

The Testo 510 differential pressure meter ensures that you as an air conditioning technician are best equipped to measure pressure differences from 0 to 100 hPa. You can select from one of ten units of measurement:

The optional pitot static tube allows you to measure the air flow in ventilation ducts from 10 to 100 m/s.

The Testo 510 – practical and accurate. And packed with special features

Accurate: temperature and air density compensated pressure difference measurements for accurate and reliable results

Easy to use: compact design; only three keys for easy use

Intelligent: magnets on the rear side of the meter that stick to almost any metal object leaving your hands free for other tasks; backlit display for use in all lighting conditions

Safe: belt bag and slip-on protective cap that ensure that your meter is stored safely; hand strap to prevent your meter from being accidentally dropped
