TSI ALNOR

TSI ALNOR is a brand under TSI Incorporated, an American manufacturer of precision measurement instruments headquartered in Shoreview, Minnesota. The brand name ALNOR is historically associated with airflow measurement instruments, particularly the Alnor brand of air velocity meters and hood kits acquired by TSI. TSI ALNOR products are designed for HVAC professionals, industrial hygienists, and facility engineers who require accurate measurement of air velocity, temperature, humidity, and indoor air quality parameters. The product families supplied by 3G Electric include hot wire anemometers, rotating vane probes, hood kits and accessories, and air velocity meters with data logging capabilities. These instruments are used for commissioning, troubleshooting, and balancing HVAC systems, as well as for indoor air quality assessments in commercial, industrial, and institutional buildings. Key technical specifications across the line include air velocity resolution down to 1 fpm, temperature accuracy of ±0.5°C, digital LCD displays, battery power sources, and NIST-traceable calibration certificates. The hot wire anemometers (e.g., MPN 9565, AVM430-A, AVM440-A) measure air velocity, relative humidity, dew point, and temperature, with data logging for trend analysis. The rotating vane accessories (e.g., MPN 801090) are add-on kits for velocity matrix measurements, compatible with specific models like the EBT731. Hood kits (e.g., MPN 801202, HMFIT, 801205, 801206) include frames, fabric, and probes for capturing airflow from diffusers and grilles, with sizes ranging from 4 ft to 10 in. 3G Electric stocks these TSI ALNOR instruments and accessories, offering global shipping and support for procurement specialists and engineers who need reliable, field-ready measurement tools. The brand's instruments are built to withstand field use, with carrying cases included for portability. No marketing claims about market leadership or awards are made; the focus is on the measurable specifications and application suitability.

Frequently asked questions

Common questions about TSI ALNOR from 3G Electric.

What is the difference between the TSI ALNOR hot wire anemometer models AVM430-A and AVM440-A?

The TSI ALNOR AVM430-A measures air velocity and temperature, while the AVM440-A adds relative humidity and dew point measurement. Both models have 1 fpm air velocity resolution, data logging, digital display, and NIST-traceable calibration. The AVM440-A includes a carrying case and provides humidity data, making it suitable for indoor air quality assessments where moisture content is relevant.

Which TSI ALNOR hood kit accessories are compatible with the EBT731 model?

Several TSI ALNOR hood kit accessories are compatible with the EBT731 model, including the Velocity Matrix Add-on Kit (MPN 801090) with two 8 ft hoses, the hood kit frame (MPN 801202) measuring 5 ft x 1 ft, and the hood kit frame (MPN 801206) measuring 4 ft. These accessories allow for airflow capture from various diffuser sizes and configurations.

Does the TSI ALNOR anemometer MPN 9565 support data logging?

Yes, the TSI ALNOR anemometer MPN 9565 supports data logging. It is a hot wire air velocity meter that measures air velocity, relative humidity, and temperature. The data logging feature allows users to record measurements over time for analysis, and it includes a USB cable for data transfer to a computer.

What calibration certificate is included with the TSI ALNOR AVM430-A?

The TSI ALNOR AVM430-A includes a NIST-traceable calibration certificate. This means the instrument's accuracy is verified against standards maintained by the National Institute of Standards and Technology, ensuring reliable measurements for HVAC balancing and commissioning tasks.

Can the TSI ALNOR hood kit HMFIT be used with the HM 650 model?
