Humidity Module FM80 (r.h.) Humidity-Temperature Sensors TFM80

General information


  • Humidity: ± 2,5% r.h. >40% r.h.
  • Temperature ± 0,5 K

POLYGA® transmitters demonstrate excellent measuring properties and accuracy in high humidity. They can be adjusted and cleaned in water. Their outstanding durability, reliability and robustness make them the classic choice for applications in food processing such as proofi ng and ripening or applications with extended high humidity.
