Duct Temperature/Humidity Sensor 

Duct Temperature Sensor 

Duct Humidity Sensor 

 
General 

Duct temperature/humidity sensor Model HTY78X3 series 
uses a platinum resistance temperature detector for a 
temperature sensing element, and a polymer capacitive 
humidity sensor (FP3

 developed by Azbil Corporation) for a 

humidity sensing element, enhancing accuracy and reliability 
of temperature/humidity sensing.   
With wide sensing range and great stability, Model HTY78X3 
series is suitable for various applications including building 
air conditioning (ducts and AHU) and meteorological 
observation as well as industrial applications.   
Model TY78X3 series temperature sensor and Model 
HY78X3 series humidity sensor are also available.

Features 

  Wide temperature/humidity sensing range with high 

accuracy. 

  Excellent long-term stability. 

 Highly 

environmental 

resistance. 

  Quick response and high repeatability. 

  Easy installation to a duct/AHU with quick-detachable 

bracket (dedicated). 

 
 

  Dust-proof and splash-proof housing (IEC IP54). 

  No filter maintenance required: 

Filterless probe of Model TY78X3Z series is the splash- 
proof enclosure.
