A Guide to Our HVAC Air Velocity Transmitters

As a globally recognized distributor of high-quality air velocity transmitters and other versatile instrumentation, JLC International continuously strives to provide our customers with the cutting-edge measurement devices needed to improve the safety and overall efficiency of many HVAC industry application.

Offering a variety of hot film air velocity anemometers featuring state-of-the-art E+E Elektronik air sensing elements, our selection of transducers set the standard for accuracy and reliability beyond traditional hot wire measurement properties. Ranging from low to medium velocity, our transmitters guarantee accuracy even in the lowest air velocities, which is not typically possible for conventional anemometers.

Each of our accurate air transmitters have low angular dependence, ensuring cost-effective insulation and are available in wall mount or duct mount styles. Some are even available in remote probe versions for flexibility across all air measurement applications.
