TESTO
0563 0510 510 Differential Pressure Meter

 0563 0510 510 Differential Pressure Meter

Heating installers and air conditioning engineers will be well-equipped with this 510 differential pressure measuring instrument from Testo. The instrument measures differential pressure from 0 to 100mbar and can help you check filters on air conditioning systems or measure static gas and gas flow pressure on heating systems, for example.

The differential pressure measurement has temperature and air density compensation for accurate readings and is small, handy and easy to operate with just three buttons. You can work with your hands free thanks to magnets on the rear of the instrument. When there is poor visibility, such as in dark surroundings, the illuminated display makes it easier to work.

The belt pouch and plug-on protective cap mean the instrument can be safely stowed away and well-secured during measurement thanks to a wrist strap.
