The ST650 Micromanometer series of manometers are an auto-ranging, auto-zeroing pocket digital manometer offering true pressure, velocity and live volume readings. Users can set the velocity resolution they need through the simple and easy to use interface. The ST650 also features a multi function, white LED, back-lit display and provides a data logging facility that can store up to 4000 readings. The instrument is powered off of 2 AA batteries.
The ST650M model measures pressure in Pa, mbar, mmH2O, mmHg and air velocity in m/sec while the ST650I model measures pressure in inH2O, inHg, PSI, and air velocity in ft/min. When ordering, be sure to select the ST650M for pressure in metric units, and select the ST650I for pressure in imperial units.
