Designed for limited spaces, the humidity indicator and a relief valve combine within the same housing for equipment or containers. The unit has separate and distinct pressure and vacuum relief settings for mounting in moisture-sensitive electronic equipment or humidity-controlled packaging enclosure. It also monitors and detects changes in space’s humidity.

As the humidity increases beyond the indication level, the sensor changes from blue to pink. As the humidity decreases, it reverts back to blue. Static desiccators can be fitted with a desiccant cartridge to adsorb and remove any moisture entering the equipment during its use. 

  • Changes from blue to pink when there is high humidity and goes back to blue when humidity decreases

  • Provides accurate and consistent pressure relief.
  • Helps to protect equipment and personnel from damage or injury due to over-pressurization.
  • Compliant with industry standards and regulations for safety and performance.

1″ Pressure Relief & Humidity Indicator Unit 

This aluminium device combines a pressure relief valve and a humidity indicator. It has a single-level indicator for 50% RH and a 1″ thread.

M24 Thread Pressure Relief & Humidity Indicator Unit 

The valve has different pressure and vacuum relief settings. The desiccant has the ability to perform three functions by using an internal thread on the rear of the unit. The threads undergo alochroming to maintain R.F. screening continuity.

¾” Thread Humi-Valve 

The breather valve is durable, lightweight, and tamper-proof. It doesn’t require field maintenance and is made of corrosion-resistant materials. Silicone rubber is used for the valve seal and comes with a manual release push button to equalise residual pressure or vacuum differentials, which makes opening the container easier. Each valve comes with a gasket, washer, and hex nut.
