Substantial impact may damage replaceable impeller.). Average life, 300 hours of use, +/-depending on backlight use. Individually tested to NIST-traceable standards (written certificate of tests available at additional charge).ĬR2032, one, included. Beyond the limits of the operational temperature range, the unit must be maintained within range and exposed for minimum time necessary to take reading.ĬE certified. The operational temperature range of the liquid crystal display and batteries is 14° F to 131° F / -10 ☌ to 55 ☌. Digit height 0.36 in / 9 mm.Īviation green electroluminescent backlight. One-button clear and restart of Max Wind Gust and Average Wind measurement. (Specification temperature limits established by WCT Tables.) Utilizes the NWS Wind Chill Temperature (WCT) Index, revised 2001, with wind speed adjusted by a factor of 1.5 to yield equivalent results to wind speed measured at 10 m above ground. Calibration drift negligible.Ĭalculated from the primary measurements of wind speed and temperature. Thermally isolated, hermetically sealed, precision thermistor mounted externally (US Patent 5,939,645). Measures air, water and snow temperature. Replacement impeller (NK PN-0801) may be field-installed without tools (US Patent 5,783,753). Sustained operation above 60 MPH / 27 m/s will wear impeller rapidly and may cause destruction of impeller.

Calibration drift < 1% after 100 hours use at 16 MPH / 7 m/s. Larger of 3% of reading or least significant digitġ inch diameter impeller with precision axle and sapphire bearings.
ANEMOMETER KESTREL SERIES
From Kestrel, the Kestrel 3500 series rotating vane weather meter designed for measuring wind speed, temperature, wind chill, humidity, heat index, dew point, barometric pressure and altitude.
