Humidity Temperature Sensor TFG80
Duct version with Polyga® measuring element

• For semi-industrial and industrial use up to 80°C and 100 % rh.
• High accuracy in the high humidity range
• Long term stability
• Robust, resistant to high humidity, with washable measuring element
• Energy saving: the TFG80H with resistance output does not require its own power supply

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 with extended high humidity.
