Features
OMEGA’s HHF91 digital anemometer is a versatile instrument for measuring air velocity, calculated air volume flow, and air temperature. Special features include the ability to switch between FPM/°F and m/sec-°C and an AUTO-OFF function that engages after 20 minutes (the AUTO-OFF function can be bypassed for continuous operation). The HHF91 can indicate average, minimum and maximum readings, and includes a hold button to freeze the display. It can also be reprogrammed with the keypad to read in either FPM/mps and °C/°F.
The kit is supplied with one handheld readout with attached velocity probe (3 foot cable), one 9 V battery, and one carrying case.
SPECIFICATIONS
Air Velocity Range: 125 to 4,900 fpm (0.7 to 25.00 mps)
Resolution: 1 fpm or 0.01 mps
Calculated Air Flow Volume: 0.0 to 9999 CFM or CMS
Display: 4 full digits, 32 x 41 mm (1¼ x 15⁄8')
RS232 Output: 2400 or 1200 baud
Accuracy:
Velocity: 2% of full scale from 200 to 4500 fpm
Temperature: ±1°F or 0.6°C
Temperature Range: -10 to 50°C (14 to 122°F), 0.1°C or °F resolution
Power Supply: 9V battery, included (100 hour life, typical)
Battery Check: Automatic low battery display
Dimensions: 181 x 70 x 35 mm (71⁄8 x 2¾ x 13⁄8') (handheld); 73 mm (27⁄8') diameter fan
Weight: ¼ kg (3 lb)

Does this come with a record of calibration?
Thank you for your inquiry. If you want a calibration certificate with an HHF-91 you will have to an HHF91-CAL-3-FLOW instead of the HHF-91.
