Four outdoor environments
For outdoor environments, the DTR502B solar radiation shield provides protection for the probe. The shield can be installed on a pole, a beam or a flat surface.

For moderate humidities and temperatures
The HMT333 is typically used in demanding HVAC applications such as cleanrooms, pharmaceutical process, and greenhouses, or in processes of moderate temperature. For environments with continuously high humidity, the HMT337 with a warmed, vapor-tight and stainless steel probe is recommended.
