Micromanometer
The micromanometer is a multifunction instrument used to measure air velocity, air flow, barometric and
differential pressure, temperature, and humidity measurements when used with the tools listed below.
The lightweight micromanometer incorporates auto-zeroing for high-accuracy, low pressure
measurements. Measurements can be stored to memory for later recall or downloaded to a PC using the
LogDat-CH software and USB cable or with Bluetooth communications.
