  • Facility managers and maintenance techs
  • Health and safety specialists for their evaluations
  • Installers of ventilation systems

What is the difference between a balometer and an air flow capture hood?

The two terms are synonymous as both instruments measure the volume of air coming out of diffusers and grilles. The term balometer was coined by Alnor as a way to simplify the name over balometercapture hoods which seems to have worked as it is now used by most HVAC service technicians.

ValueTesters carries balometers of all sizes from all major brands. Each hood size has certain benefits depending on application including: evaluating thermal comfort, HVAC testing, adjusting and balancing of HVAC systems, HVAC commissioning, troubleshooting of HVAC systems, or even clean room certification. Our customer service specialists can help you select the best product to meet your needs, as well as assist you with your exclusive pricing.

Additional Accessories

TSI Alnor also has additional tools for the micromanometer allowing it to be used in a variety of applications. Optional pitot, air flow (straight pitot), temperature/relative humidity, velocity matrix, or plug and play thermoanemometer probes enables use in multiple applications.

The Pitot tube is used to measure air velocity, air volume, and velocity pressure in a ductwork. This accessory is available in a variety of sizes.

Pitot Probes:

Part NumberPitot Tube Size
6346340005/16 - 12" (8mm - 30cm) diameter
6346340015/16 - 18" (8mm - 46cm) diameter
6346340025/16 - 24" (8mm - 61cm) diameter
634634003 5/16 - 36” (8mm - 91cm) diameter
6346340055/16 - 60” (8mm – 152cm) diameter

Velocity Matrix (p/n 801090) is used for measuring face velocities of HEPA filters, chemical fume hood, laminar flow benches, filter banks, kitchen exhausts, and other applications where a large surface area needs to be measured. The 16 point velocity matrix with a telescopic handle has a grid that covers 1 ft² and averages the air velocity while minimizing the effects of turbulence to produce a stable reading.

Air Flow Probe (p/n 800187) is a straight probe used to measure a single point air velocity or air volume measurement in ductwork.

Temperature /Humidity Probe (p/n 800220) is a telescopic probe that extends from 9-39”. This probe is used for measuring inside of duct work with the ability to calculate wet bulb and dew point temperatures.

Thermoanemometer Probes are available in straight or articulating construction and with or without a relative humidity sensor. These probes can also 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. Models with a relative humidity sensor can also calculate wet bulb and dewpoint temperature.

Thermoanemometer Probes:

ModelDescription
960Air Velocity and Temperature, Straight Probe
962Air Velocity and Temperature, Articulating Probe
964Air Velocity, Temperature, and Humidity, Straight Probe
966Air Velocity, Temperature, and Humidity, Articulating Probe

Balometer Capture Hoods are used to obtain volumetric air flow measurements through diffusers, registers, and grilles. The 2’ x 2’ come standard with the EBT731, but other sizes are available. Please see the table below for the additional sizes available.

You can also purchase the EBT731-STA that includes a stand that extends up to 15’ and a Smart Tablet loaded with LogDat mobile app and instruction videos.

If you are interested in purchasing one of the accessory probes and it is not found on the website, please contact customer service at 602-795-8292 and we will be happy to add it to your order.
