Expert Testing, Balancing and Adjustment

The THB Company utilizes state-of-the-art air balancing, testing and adjusting equipment including flow hoods, flowmeters, indoor air quality meters, ventilation test instruments and aerosol and dust meters. We specialize in green building testing and adjustment and in the testing, balancing and adjustment of Class 1 clean rooms like the Boston Medical Center's Cyberknife facility pictured right.


Airflow Capture Hood: By placing a capture hood over a diffuser or grille, a technician can measure air volume in order to balance buildings and verify air flow distribution. Hoods are equipped with analog meters for quick measurements and can be utilized with a wide range of common balance and test tools such as air foil, pitot, relative humidity, and temperature probes. Capture Hoods are an ideal way to measure very low volumetric flow.

Digital Strobotachometer:The Strobotachometer is an instrument used to inspect and measure the speed of moving gears, fans, centribiges, pumps, motors and other equipment used in general industrial maintenance, production, quality control and in laboratories. A stroboscope, also known as a strobe, is an instrument used to make a cyclically moving object appear to be slow-moving, or stationary. The principle is used for the study of rotating, reciprocating, oscillating or vibrating objects. Machine parts and vibrating strings are common examples.

Infrared Thermometer: An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called blackbody radiation emitted by the object being measured. They are sometimes called non-contact thermometers or temperature guns, to describe the device's ability to measure temperature from a distance. By measuring infrared radiation, the thermometer can tell you the temperature of any surface with the touch of a button. Lightweight and portable, it's useful for many HVAC applications.

Micromanometer:This device allows professional HVAC engineers to easily make HVAC pressure measurements in air ducts. These robust instruments can be used with probes to measure duct velocity. Micromanometer are used for fast, accurate differential and static pressure measurements.
