Through-Wall Humidity and Temperature Meters

Mount these meters through the wall of a sealed container or package to monitor relative humidity, temperature, and dew points without exposing the contents to dust and water. Check the readings on an easy-to-read LED display. Made of aluminum, the housing is lightweight and resists corrosion.

Monitor humidity in sealed containers without opening them, protecting the inside from contamination. These plugs are often used on plastic bags, storage containers, and electrical housings. Consisting of a mounting nut and two gaskets for a tight seal, these plugs install through a hole in a flexible barrier. Remove one gasket and reverse the nut to install plugs in a rigid container. Watch the indicator disc through the nut’s viewing window—it will change color as humidity rises and falls. Made of anodized aluminum, these plugs resist corrosion and are lightweight. They meet military and SAE standards for humidity indicators.

The viewing window on reverse-mounting plugs is on the threaded side, so the nut will be threaded on the outside of your container. They’re easier to install than standard plugs.
