Fischer Humidity & Temperature - Dial w/ White Face & Brass Case.

NIST Certification available/

Test certificate included! A beautiful Fischer / Lufft instrument with easy-to-read face. These units have been giving accurate readings for many years. Made in Germany by Fischer / Lufft and accurate to ±3% + 1 scale division (30 to 95% relative humidity and ±1°C (0 - 40° C) + 1 scale graduation on the temperature.

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 temperature is indicated by the actuation of a bimetallic spring which transmits changes by expansion and contraction. The calibration and certification are done under ISO-9001 control.
