Humidity indicators combined with relief valves are designed for compact spaces, requiring only one hole for installation in equipment or containers.
The reversible humidity indicator features a colour-changing sensor paper that turns pink when humidity levels increase and returns to blue when levels return to normal. Desiccant cartridges or static desiccators filled with silica gel or molecular sieves desiccants can be added to absorb moisture that may enter the equipment during application.
- Clear window to observe and monitor changes in humidity level
- Distinctive colour change indication
- Reversible and non-reversible options
- Available in plastic or metal housings
3/4”Thread Humi-Valve (BLD9720/01-06)
