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.

Frequently asked questions

Common questions about TSI ALNOR from 3G Electric.

What types of air velocity meters does TSI Alnor offer?

TSI Alnor offers several hot wire air velocity meters, including the AVM410, AVM430-A, AVM440-A, 9535, 9535-A, and 9565. These instruments measure air velocity with a resolution of 1 fpm and can also measure temperature, humidity, dew point, and wet bulb depending on the model. The AVM410 is specifically designed for low-velocity measurements under 100 fpm. Many models include data logging, digital LCD displays, and carrying cases. The 9565 includes a USB cable for data transfer. All are battery-powered and suitable for portable use in HVAC and industrial hygiene applications.

What is the particle size range for TSI Alnor particle counters?

The TSI Alnor 9303-01 particle counter is a 3-channel instrument that measures airborne particle concentrations. It has a 10% coincidence loss at 3,400,000 particles per cubic foot. The specific particle size channels are not detailed in the provided specifications, but typical TSI Alnor particle counters detect particles in the 0.3 to 10 micrometer range. For exact channel sizes, please consult the product datasheet. The instrument includes a calibration certificate and NIST-traceable calibration, ensuring accurate and reliable measurements for cleanroom monitoring and indoor air quality assessments.

Does the TSI Alnor 7515 gas analyzer measure carbon dioxide only?

The TSI Alnor 7515 indoor air quality tester is a battery-powered gas analyzer for carbon dioxide. It also measures relative humidity. It features a user-selectable sampling rate and an LCD digital display. The carbon dioxide accuracy is ±3% of reading or ±50 ppm, whichever is greater. It includes a NIST calibration certificate and carrying case. This instrument is suitable for monitoring indoor air quality in buildings, schools, and offices. It does not measure other gases such as carbon monoxide or volatile organic compounds; for those, other TSI Alnor models may be available.

Are TSI Alnor instruments calibrated and traceable?

Many TSI Alnor instruments come with NIST-traceable calibration certificates. For example, the AVM430-A, AVM440-A, 9303-01 particle counter, and 7515 gas analyzer include calibration certificates. The 9535 and 9535-A models also include calibration certificates. This ensures that measurements are traceable to national standards, which is important for regulatory compliance and quality assurance. Calibration intervals depend on usage and industry requirements; TSI Alnor recommends annual recalibration. 3G Electric can provide calibration certificates with the instruments and can assist with arranging recalibration services if needed.

What is the difference between the TSI Alnor 9535 and 9535-A?

The TSI Alnor 9535 and 9535-A are both hot wire air velocity meters with a resolution of 1 fpm and a minimum measured velocity under 100 fpm. Both measure air velocity and temperature, feature data logging, and include a calibration certificate. The 9535-A additionally measures wet bulb temperature. Both have a digital LCD display and are battery-powered. The 9535-A includes a carrying case, while the 9535 includes a calibration certificate. For detailed specifications, please refer to the individual product datasheets. 3G Electric stocks both models and can provide quotes.

Can TSI Alnor instruments be used for cleanroom certification?

TSI Alnor particle counters, such as the 9303-01, are suitable for cleanroom monitoring and certification when used according to applicable standards. The 9303-01 provides 3-channel particle counting with NIST-traceable calibration. For cleanroom certification, you may also need a capture hood or anemometer to measure airflow. TSI Alnor offers a range of instruments for these applications. However, certification requirements vary by cleanroom class and standard (e.g., ISO 14644, FS 209E). It is the responsibility of the user to ensure that the selected instruments meet the specific requirements of the certification protocol. 3G Electric can supply the instruments but does not provide certification services.
