The testo 512-1 is a great lower cost alternative to a second blower door gauge for zonal pressure testing. The 512-1 allows you to easily make HVAC pressure measurements. These robust instruments can be used with Pitot probes to measure duct velocity. The 512-1 is a simple to operate, hand held digital Micromanometer for fast, accurate differential and static pressure measurements.
digital manometer +/- 1 IWC (+/-200 Pa), incl. battery and calibration certificate
testo 512 shows pressure and flow velocity simultaneously in an easy-to-read, large, backlit display.
Measurement data may be printed on site with date and time as well as minimum and maximum values (optional printer).
testo 512 has two switchable units for flow: m/s and fpm.
Adjustable damping for sliding mean calculation, density compensation is built-in.
The displayed actual value can be frozen in the display by pressing the HOLD button.
The measured minimum and maximum value can be displayed and stored in the meter.
OPTIONAL TopSafe protects the measuring instrument in the field from impact, dirt and splash water.
