225-HMP155 Series Relative Humidity and Temperature Sensors
The 225-HMP155 Series of relative humidity and temperature sensors feature a new generation HUMICAP® 180R sensor with excellent stability that can withstand harsh environments. The HMP155 temperature probe’s fast response time makes it ideal for measuring changing temperatures.
The 225-HMP155 Series of relative humidity and temperature sensors feature a new generation HUMICAP® 180R sensor with excellent stability that can withstand harsh environments. The solid probe structure and sintered Teflon filter provide maximum protection against liquid water, dust, and dirt. The temperature probe's fast response time makes it ideal for measuring environments with changing temperatures. The new membrane filter speeds up RH measurement.
Extending the sensor's lifespan requires protecting it from scattered and direct sunlight, as well as precipitation. Therefore, NovaLynx recommends installing the HMP155 in a solar radiation shield or instrument shelter.
