WD-20250-14 CFM/CMM Vane Thermoanemometer with NIST Traceable Calibration by Digi-Sense
The Digi-Sense CFM/CMM Vane Thermoanemometer (Model 20250-14) measures air velocity, airflow (volume), and temperature. The large, easy-to-read backlit LCD includes primary and secondary displays plus numerous status indicators. The meter features 2 memory locations (1 for CFM and 1 for CMM) to store and recall commonly used area sizes. The instrument is fully tested and calibrated to NIST-traceable standards. Careful use of this meter will provide years of reliable service.
Features
- Reliable measurements, guaranteed! Precalibrated to NIST-traceable standards.
- User-selectable units of measure eliminate the need for conversion
- Measure air velocities up to 5900 ft/min (30 m/s) to cover a broad range of applications
- Measure air flow up to 999,900 CFM, 999,900 CMM
- Two memory locations, one CFM and one CMM, store commonly used vent area sizes to save you time
- Large dual-function 4-digit LCD with backlight for easy reading
- Auto power-off extends battery life
- Fits comfortably in your hand
Includes
Vane probe sensor with 3.9-ft (1.2-m) cable, three AAA batteries, and NIST-traceable calibration report with data supplied by InnoCal.
