It can also be used as a flow measurement instrument. However, outdoor use is also possible.ĭepending on the instrument, you have the option of not just using the vane anemometer to measure wind speed. This makes it very easy to do a flow measurement in the duct. Most models are fitted with a telescopic probe. The vane anemometer is ideally suited for this. Depending on the design, it can very easily be inserted into the ventilation shaft via a telescope, so that it can carry out measurements there. This is where the anemometer comes into its own. The problem here is that it is not always easy to control ventilation systems. If these values are not correct or change, it may affect the indoor air quality. Ventilation systems are based on airspeed, temperature and humidity. In particular, it may make sense to use one for the measurement of air velocities in rooms. However, it is in fact not only outdoors that a wind speed meter is used. Additional NIST Calibration and Certification services are available.Measuring wind speed is a concept that many users associate above all with outdoor use. Every Kestrel Meter comes with a Certificate of Conformity to document the units accuracyall Kestrel measurements are traceable to the National Institute of Standards and Technology, ensuring the highest level of reliability. Kestrel Meters are designed and manufactured at NK's facility in Boothwyn, Pennsylvania, and are individually calibrated at the time of manufacture. 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.

CR2032 coin cell battery (Average life 300 hours).All instruments and accessories are completely assembled in the USA.Wide range of wind speeds and low startup speed.Protective cover with sure-grip overmolding.Kestrel Meters kept riders and spectators abreast of the weather conditions at the 2006 ESPN X Games in Aspen, Colorado, and were used by the 2006 US Biathlon Olympic Team in Turin to measure air and snow temperature to aid in ski-wax selection decisions and measure the wind downrange. Thanks to the patented external temperature sensor, the Kestrel 2000 can take accurate water and snow temperature readings, and since it is isolated from the case, you can be sure that the temperature the Kestrel Meter is reading is accurate and not influenced by your hand warming the unit. Winter sports enthusiasts around the world love Kestrel Meters. Whether contemplating which wet suit the cold water warrants, or checking to see how low the wind chill can go in the blind, the Kestrel 2000 is the easy-to-use tool you need. For those of you who like to know just how cold and windy it really is, the Kestrel 2000 Pocket Wind Meter is your reality check.
