testo 510 - Differential pressure meter

Order-Nr.  0560 0510

  • Differential pressure from 0 to 100 hPa 

  • 10 Measurement unitsto choose from (hPa, mbar, mmHg, psi, m/s, fpm) 

  • Air flow measurements 

  • Temperature and air density compensation 

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. 

Product Description

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:

| psi | fpm | inH2O | inHg | hPa | Pa | mbar | mmH2O | mmHg | m/s |

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

Differential pressure measurement on filters

Air conditioning systems are equipped with filters which prevent dirt from the outside air entering the indoor air. These filters are to be inspected regularly to make sure they are still fully functional. To do this, the pressure is measured in front of and behind the filter. The result is the differential pressure. If it is too high, the filter is contaminated and needs changing.

The testo 510 measures differential pressures in a range of 0 - 100 hPa. The differential pressure measurement is temperature-compensated for exact readings. The readings can be displayed in pascal over the entire measuring range. Magnets on the rear of the instrument allow hands-free work.

Measurement in ventilation ducts

Observance of air flows in the ventilation duct is of utmost importance for the function of the ventilation and air conditioning system. If the air flows are smaller than intended, the removal of room loads (heating, cooling and substance loads) may not be ensured in certain circumstances.

Therefore, the most accurate recording of air flows as possible is particularly important.

In conjunction with a pitot tube, testo 510 measures the air velocity in the range of 10 to 100 m/s. Magnets on the rear of the instrument allow hands-free work.
