The T9501 harsh environment RH and Temp. sensor can be used in most any non-traditional environment in which temperature and humidity need to be monitored and measured. Some examples of these applications include energy saving HVAC control applications such as air conditioning, refrigeration, indoor air quality (IAQ), vent fans, home appliances, humidifiers, dehumidifiers, and marine environments. The T9501 can also be installed in process control and instrumentation applications, such as agriculture and indoor growing, medical instruments, handheld devices, weatherstations, and food processing facilities.
