|  | Abbeon TAB77 TAB-77 Certified Thermometer, Fahrenheit and Celsius w/ FREE UPSIn Germany, Lufft has been making fine meteorological instruments for over 100 years.
Abbeon has been offering their high quality instruments here in the U.S. for over forty years.
The Lufft instruments shown here have white faceplates with black lettering. (Red lettering is added for Celsius scales when they are included). The humidity is sensed by a Durotherm element that is a synthetic hygroscopic fiber that expands and contracts in response to the moisture in the air. The thermometers are actuated by bimetallic springs which transmit changes in temperature through expansion and contraction.
Accuracy for these instruments are ±3% for the relative humidity and ±2°F for the temperature.
The easy-to-read 5-inch dial indicates the temperature in a range of -20 to 120° Fahrenheit or
-30 to 50° Celsius. The pointer actuated by a bi-metallic strip, reads with an accuracy of ±1% of
scale.
