These TSI micromanometers measure and monitor airflow and pressure. The PVM610 measures differential and static pressure and velocity using a pitot tube. It does not include features such as sample statistics, volumetric flow rate, or data logging capabilities. The PVM620 includes sample statistics and a volumetric flow rate. It also has data logging software (LogDat2), a K factor, and the ability to measure actual and standard velocity with a variable time constant.

1Overpressure range = 7 psi (190 in. H2O, 360 mmHg, 48 kPa). 2 Pressure velocity measurements are not recommended below 1000 ft/min (5 m/s). 3 Accuracy is a function of converting pressure to velocity. Conversion accuracy improves when actual pressure values increase. |
