Available Tools

This section gives a brief description of available tools for the micromanometer.

Pitot Tube

The pitot tube is primarily used to obtain air velocity, air volume, and velocity pressure measurements
within ductwork.

Static Pressure Probe

The static pressure probe is primarily used to obtain static pressure measurements within ductwork.
Differential pressure measurements across a filter or coil can also be performed by placing one probe
upstream and the other downstream of the filter or coil.

ProHood Capture Hoods

Capture hoods are used to obtain volumetric air flow measurements through diffusers, registers and
grilles. Capture hoods are available in a kit with one 2 ft.  2 ft. (610 mm  610 mm) fabric hood, frame,
and base assembly. Alternate hood sizes are available. Descriptions and part numbers can be found in
Table 2 of Chapter 2 of this manual.

Velocity Matrix

The velocity matrix is used to obtain area-averaged multi-point air velocity measurements useful in
laboratory hood face velocity testing, filter face velocity testing, and other applications such as kitchen
exhaust.

Air Flow Probe

The air flow probe model 800187 is an 18" (46 cm) straight pitot tube used to obtain single point air
velocity or air volume measurements in ductwork.

Temperature/Humidity Probe

The temperature/humidity probe is used to obtain temperature measurements over the range of 14 to
140°F (-10 to 60°C), humidity measurements over the range of 5 to 95% RH, along with calculated wet
bulb temperature of 40 to 140°F (4 to 60°C) and dewpoint temperature of 5 to 120°F (-15 to 49°C).

Thermoanemometer Probes

Thermoanemometer probes can be used to measure air temperature, air velocities or air volume
measurements in ductwork as well as lower velocity applications such as face velocity measurements of
chemical fume hoods, biological safety cabinets and filtration systems. Four models are available in
straight or articulating construction, and with or without a relative humidity sensor. Models with a relative
humidity sensor can also calculate wet bulb and dewpoint temperature.
