Remote-Reading Airflow/Temperature Meters

With a probe on a cord, these meters access hard-to-reach places in duct. They display airflow and temperature simultaneously and can show airflow measurements on multiple scales, such as fpm, mph, and knots. Also known as anemometers.

Fan meters are also known as vane meters. Those with a built-in surface temperature thermometer also measure the temperature of hard-to-reach surfaces. Mini fan meters have a fan at the end of a telescoping probe. You can also use them to measure humidity.

Pilot tube meters measure a wider airflow range than other meters. They also measure differential pressure.

Telescoping tube meters are also known as hot wire meters. They have a probe that telescopes to reach into narrow openings.

Meters with an SD card data connection store timestamped readings on an SD card in Excel format, for easy datalogging and PC transfer. Meters with a 3.5 mm audio data connection can transmit data through a USB connection using a USB adapter cord (sold separately, except for Style C). Meters with a mini-USB and micro-USB connection type transmit data to your PC through the included cable.
