About TSI ALNOR

TSI Alnor is a product line within TSI Incorporated, a company founded in 1961 and headquartered in Shoreview, Minnesota. TSI designs and manufactures precision measurement instruments for applications in indoor air quality, occupational hygiene, and environmental monitoring. The TSI Alnor brand specifically encompasses a range of portable and handheld instruments used to measure air velocity, temperature, humidity, dew point, and particle concentrations. These instruments are commonly deployed by HVAC professionals, industrial hygienists, and facility engineers to verify ventilation performance, assess indoor air quality, and ensure compliance with workplace safety standards. The product families include hot wire air velocity meters, capture hoods, particle counters, and gas analyzers for carbon dioxide. Many models feature data logging, digital LCD displays, and NIST-traceable calibration certificates. For example, the AVM430-A and AVM440-A hot wire air velocity meters measure air velocity, temperature, dew point, and relative humidity with a resolution of 1 fpm. The 9535 and 9535-A models add wet bulb measurement and include carrying cases. The 9565 anemometer measures air velocity, relative humidity, and temperature, and includes a USB cable for data transfer. The AVM410 is designed for low-velocity measurements under 100 fpm. Particle counters, such as the 9303-01, provide 3-channel detection with a 10% coincidence loss at 3,400,000 particles per cubic foot and include air temperature measurement. The 7515 indoor air quality tester is a battery-powered carbon dioxide analyzer with user-selectable sampling rate and relative humidity measurement. These instruments are used in a variety of settings, including commercial buildings, hospitals, laboratories, and industrial facilities. 3G Electric supplies TSI Alnor instruments globally, offering multiple SKUs, datasheets, and logistics support. Our catalog includes hot wire anemometers, particle counters, and gas analyzers, all available for quote. We serve plant engineers, maintenance managers, and procurement specialists who require reliable measurement tools for air velocity, temperature, humidity, and particle concentration. The TSI Alnor line is known for its robust construction and adherence to calibration standards, with many products featuring NIST-traceable calibration. This ensures that measurements are accurate and repeatable, which is critical for regulatory compliance and process optimization. 3G Electric provides access to these instruments along with technical documentation to support selection and integration. Whether you need to monitor airflow in a cleanroom, verify HVAC system performance, or assess indoor air quality, TSI Alnor offers a range of solutions. Our team can assist with product selection, lead times, and shipping to your location. We maintain inventory of popular models and can source additional SKUs as needed.
