ALNOR® INSTRUMENTS
Rugged. Reliable. Professional.
HVAC contractors, facility personnel, building engineers, safety officers, and industrial hygienists around the world use and trust Alnor® brand handheld instruments. Alnor Instrument Co. (originally called Illinois Testing Laboratories) began operation in 1919 in Chicago, Illinois, as a repair and service center for precision instrumentation.
Over the years, the Alnor product line has grown by responding to the need for key new products and technologies. Introduced in the 1930s and still widely used today, the Alnor Velometer and the Velometer Jr. began the long series of popular products. More recently introduced products, such as the Balometer Capture Hoods, are standards of performance in HVAC testing and balancing. And in less than two decades the AirGard® series of alarms and monitors have become an industry leader in both new and retrofit lab hood monitor installations.
In 1995, the Alnor Instrument Company was acquired by TSI Incorporated. Today the long tradition of providing reliable, durable, affordable Alnor brand instrumentation continues at the manufacturing, engineering, sales, and service facilities of TSI Incorporated in Shoreview, Minnesota.
