Alnor Instrument
Alnor Instrument Co. (originally called Illinois Testing Laboratories) started in 1919 in Chicago, Illinois as a repair and service center for precision instrumentation. The Alnor Pyrometer was the first instrument to be marketed. In 1920, manufacturing and sales rights were purchased for the Crit Point Instrument; in 1930, the Price Instrument and Pyrometer Company was acquired; in 1934, the manufacturing rights and patent for a line of instruments for detection of contraband material was purchased. These instruments, such as the Electronic Eye and Metal Detector, were used across the country in penal institutions.
In 1998, Alnor introduced the LoFlo Balometer®, a new standard for low volume measurement, and a new family of CompuFlow instruments with datalogging capability. A new water pressure meter, the HM 650 Hydronic Manometer, started shipping in 1999. New instruments for IAQ applications introduced in 2000, including two carbon dioxide instruments and two thermo-hygrometers, further increased the number of diagnostic tools available.
Alnor's reputation within the industrial hygiene, HVAC contractor, and test and balance market is unsurpassed. Additionally, facility maintenance personnel and building engineers rely on Alnor brand instruments to help them more efficiently address IAQ issues in their buildings.
The long Alnor tradition of providing reliable, durable instrumentation continues at the manufacturing, engineering, sales, and service facilities of TSI Incorporated in Shoreview, Minnesota and DICKEY-john in Auburn, Illinois.
