Kestrel® 4300 Construction Weather Tracker

A weather meter designed specifically for construction professionals

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. Weather meter includes soft carry pouch, lanyard and user-replaceable batteries. Assembled in the USA.
