Combined Indicators & Relief Valves

Combined Indicators & Relief Valves are designed for places with limited spaces, requiring one hole to fit into equipment or containers. As this indicator is reversible, the sensor paper will change from blue to pink when humidity increases, reverting to blue as humidity returns to normal. Desiccant cartridges are additional units, also known as static desiccators. These desiccators are optional tools that can fit into most of our combined indicators & relief valves, adsorbing moisture entering the equipment during its use.

Stream Peak offers our indicator and relief valve in 4 different models:
