Ventilation Testing and Balancing Instruments

For over 80 years, Alnor has been the instrumentation brand of choice for HVAC contractors, test and balance professionals, plant engineers, and consultants.

Alnor provides excellent tools to verify air flow distribution and balance buildings. An improperly balanced building can require more cooling or heating than a correctly balanced building. Testing, adjusting, and balancing an HVAC system can save money through decreased energy costs. Properly balanced buildings means satisfied occupants, owners, and building engineers.

The Alnor ventilation testing and balancing instruments measure air volume, air velocity, pressure, CO₂ concentration, temperature, and humidity using a variety of sensing techniques. They are easy-to-use, rugged, and reliable.

For more information, choose from the following ventilation testing and balancing instruments:
