Product Information

Kestrel ® 4300 Construction Weather Tracker

The Kestrel ® 4300 Construction Weather Tracker measures the same parameters as the Kestrel ® 4000 (Item No. R4000) while also displaying the evaporation rate. Knowing the evaporation rate — a function of relative humidity, temperature and wind speed — improves your results when doing surface coating and pouring concrete. Includes soft carry pouch, lanyard and user-replaceable batteries. Assembled in the USA.
