About this product

Monitor temperature, humidity and condensation inside your motorhome with the Hook-In Climate Monitor, a compact digital hygrometer designed specifically for the Hymer Hook-In multifunction rail (2024 onwards). It clips securely into the rail in seconds, or stands freely on any flat surface.

I designed this after wanting a proper way to keep an eye on conditions inside my own Hymer ML-T, without another loose gadget cluttering the worktop.

Excess humidity inside a motorhome can lead to condensation, damp and mould. This hygrometer helps you keep an eye on conditions year-round, whether you're travelling, storing the vehicle over winter, or checking overnight comfort in summer.

Compatibility: Fits Hymer Hook-In multifunction rails — ML-T, B-Class, Grand Canyon, Venture S, Ayers Rock, Yellowstone, Yosemite, Crosstrail, Crossover, and Eriba (2024 onwards). Does not fit Dethleffs aluminium rails, Häfele rails, or older Hymer models with the twist-lock bar rail. Not sure which rail you have? See our rail guide or message us before ordering.
