Humidity Indicators with Relief Valve
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
¾” Thread Humi-Valve (BLD9720/01-06)
The ¾” thread humid-valve combines a humidity indicator and a two-way breather valve in one housing, eliminating the need for an extra hole in the container. The valve is designed with separate pressure and vacuum relief settings and features a specific path to the humidity indicator.
The lightweight and rugged breather valve is tamper-proof and requires no field maintenance. Made of corrosion-resistant materials, the valve is built to last and features a silicone rubber seal. The manual release push button allows users to equalise residual pressure or vacuum differentials, making it easier to open the container. Each valve has a gasket, washer, and hex nut, making installing it easy.
