| Wind chill equivalent temperature calculation | Utilises the (US) NWS Wind Chill Temperature (WCT) Index, revised 2001, with wind speed adjusted by a factor of 1.5 to yield equivalent results for wind speed measured at 10m above ground | ||
| Certification | Wind speed and temperature measurements are tested during
manufacture. A certificate of conformity (C of C) is included with each Kestrel. A calibration certificate is available for an additional fee. |
||
| Guarantee | 5 years | ||
