PDM - Portable Digital Micromanometers
Differential Pressure and Velocity Meters

 

Typical PDM - Micromanometer Applications:

•  Measurement of system pressures in heating, ventilation and air conditioning  (HVAC) systems
•  Perfect for HVAC technicians performing Pitot tube traverses of airflow readings across a duct
•  Monitoring differential pressure across filters and coils in HVAC systems
•  Measuring positive and negative pressure in air conditioning ducts
•  Measuring differential pressure for clean room monitoring

Dwyer Series 477-FM Digital Manometers
Intrinsically Safe with ±0.5% Accuracy

The Series 477-FM portable digital micromanometers (PDM) includes 11 meters with ranges from 0-200" H2O / 0-150 psi and measure positive, negative or differential pressures. Users can select to display from 9 switchable pressure units: psid, inch H2O, mm H2O, inch Hg, mmHg, kPa, Pa, bar, mbar. The Dwyer 477-FM is FM approved Intrinsically Safe for Hazardous Locations, Class 1, Div. 1, Group A, B, C, D, T4.

Greywolf Sensing Solutions / Solomat Zephyr II+
Micromanomter with HVAC 3-Function Probe

The Graywofl/Solomat Zephyr II+ Micromanometer with 3-function probe are designed to measure differential pressure, static pressure and temperature.The Zephyr II instruments have a built-in auto-zeroing micro-manometer, a 'K'-type thermocouple input and 2 BIN type connectors. Used with a pitot tube, the Zephyr II provides direct air velocity readings.

Optional probes such as the telescoping 3-function “smart” probe for temperature, humidity and air flow (hot wire) can be quickly connected. The auto-zeroing feature allows for highly accurate differential pressure logging over time.

Testo Pocket Pro 510 Micromanometer
Differential Pressure & Velocity

The Testo 510 PocketPro portable digital micromanometer has a measurement range of ±40" H2O, with air density compensation and a display resolution of 0.01" H2O. User can select from 10 units of measurement: hPa, mbar, Pa, mm H2O, mm Hg, in H2O, in Hg, psi. It will display air velocity in fpm or m/s when used with an optional Pitot tube. A magnetic back aids in hands free use. WolfSense software make it a very versatile HVAC troubleshooting tool. Is not intrinsically safe.
