Carry out pressure difference measurements at A/C system filters or air flow measurements in ventilation ducts using a pitot static tube. Field tested and ideal for installation and maintenance work in and around ventilation and air conditioning.
* 0 to 40" H2O pressure measurement range
* Temperature compensated pressure sensor
* Magnetic backing for hands free use
* Air flow measurement with optional pitot tube
* User adjustable air density compensation
* Protective cap for safe storage
differential pressure measurement is temperature-compensated for accurate measurement values which can be displayed in Inches of Water Column over the entire measurement range. Magnets on the back of the 510 permit hands free work. The backlit display allows the measurement values to be easily read out, even in unfavorable light conditions. The testo 510, in combination with an optional Pitot tube, measures air flow velocity. For accurate measurement values, the air density can be compensated.
