The PV350 Pressure/Vacuum Transducer Module (the module) measures gauge pressure; the difference between atmospheric (barometric) pressure and the pressure (or vacuum) applied to the pressure port on the transducer. It then converts that measurement to 1 mV dc per unit. A module and a high-performance digital multimeter (DMM) with min/max function become a datalogger capable of measuring peak high and peak low.

Identify areas with low or substandard ventilation. Identify hidden energy savings in over-ventilated spaces. Determine if ventilation is a factor in air quality complaints. Locate the presence of combustion fumes from vehicles and appliances. Use as a reference to calibrate wall mounted CO2 sensors.
