Thermo-Hygrograph Model 8145 Model 8145 Thermo-Hygrograph records precise measurements of temperature and humidity. The Durotherm sensing element for humidity will not dry out or get brittle with age - but will go on year after year recording the humidity of the air. It is temperature-compensated by a bimetallic strip which eliminates the expansion of the Durotherm elements due to temperature variations. Lufft's Thermo-Hygrographs differ from other manufacturers' units in this respect. The bimetallic temperature sensing element actuates the arm that records minute temperature changes. Easily calibrated. Can be certified to NIST
