There’s finally a convenient way to protect your sensitive cameras from excess humidity and ambient relative humidity fluctuations: this Dehumidifying Body Cap for Nikon from Brno. The cap holds a replaceable silica gel and protects your precious Nikon equipment from moisture that can lead to fungus or mold.
Simply put the cap on a camera, and it will maintain the optimum relative humidity (RH) of 35% to 45%. The caps are ideal for protecting equipment from fluctuating RH and minimizing condensation build-up in climates with excessive changes in temperature–even moving from air conditioning to a hot humid environment will create unhealthy moisture in a camera. Each silica gel changes color from orange to green when it needs changing. One rear lens cap for Nikon lenses is included, along with 4 silica gels.
