Panel-Mount Humidity Controllers
The sensor monitors relative humidity and triggers the controller to turn equipment on or off. Sensor and controller are sold separately.
Controller is SPDT (single pole, double throw). It can be set to turn one circuit from off to on (normally open) or from on to off (normally closed). Set the actuation point with the keypad.

Enclosure Humidistats
Reduce the humidity in your enclosure to prevent condensation that can cause corrosion and short circuits. These humidistats switch your heater on when the enclosure reaches the relative humidity setting. Once the humidity falls by 5%, the heater switches off. To install, clip humidistats to a DIN rail.
Nonadjustable humidistats work for most applications. They keep humidity below 65%, which is when condensation is most likely to form. Since they aren’t adjustable, the humidity setting can’t be tampered with or accidentally changed. For critical components, use adjustable humidistats to set the relative humidity you need in your enclosure. Use a lower humidity setting in damp environments and places with frequent temperature changes. Condensation is more likely in these situations.
CSA Certified, CSA-US Certified, CE Marked, and VDE Certified, these humidistats meet American, Canadian, and European safety standards. They also meet UL 94 V-0, so if they catch fire, they self-extinguish within 10 seconds and won’t spread the fire by dripping.

Indicating Desiccant Bags
Know when it's time to change these desiccants—they turn from blue to pink after absorbing 8% of their weight. Use to remove moisture from sealed containers during shipping and storage.
These desiccants are best when relative humidity is at least 40%. The area covered is calculated at 77° F and 40% relative humidity.
The bags have a monitoring window to check for desiccant color change.

Rechargeable Small-Space Dehumidifiers
Place these dehumidifiers in small spaces to protect moisture-sensitive materials such as photo lenses or 3D printing filaments. They absorb moisture with a silica gel that changes color, letting you know when they’re saturated. While they don’t need a battery or power cord during use, you do plug them in to dry them out—unlike other desiccants, they don’t require an oven.
