 Description 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. The humidity sensor 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 humidity arm is actuated by the sensing element to record minute changes in humidity. The bimetallic temperature sensing element actuates the arm that records small temperature changes. Easily calibrated. Can be certified to NIST Specifications Temperature Accuracy: ±1% of full scale Temperature Sensor: Bimetallic spring Temperature Chart Increments: 2° divisions Relative Humidity Range: 0 to 100% Relative Humidity Accuracy: ±3% Relative Humidity Relative Humidity Sensor: Durotherm Element Relative Humidity Chart Increments: 2% divisions Recording Pens: Long-writing felt tipped nibs (two included) Charts: One year supply, 55 charts, included.
