Differential pressure
measurement
testo 510i: Bluetooth Differential
pressure manometer
- Measures static pressure, air flow, and
volume flow (Pitot tube not incl.)
- Measures air handler manifold pressure
and pressure drop (with alarms) across
filters and coils
- Easy configuration and calculations for
volume flow using pitot tube (must enter
pitot tube factor and dimensions)
- Measuring range -60 to 60 inWC
- Measuring Units mbar, hPa, Pa, mmHg,
inHg, inWC, psi, mmWC, m/s, fpm, m

/h,
cfm, l/s
testo 549i: Bluetooth high-pressure
probe
- Measures high-side or low-side refrigerant
pressure (simultaneously with 2 probes) in
AC/refrigeration systems
- No hoses required! Clean, simple,
accurate
- Low-loss refrigerant pressure testing!
- Use with 115i pipe-clamp temp. probes
for automatic superheat / sub-cooling
calculations
- Measuring range -14 to 870 psi
- Measuring Units bar, psi, MPa, kPa
