The display cabinet bushing for temperature and humidity probes is ideal for measurements in display cabinets and presentation cases. Install the display cabinet bushing in the base plate of your display cabinet. The diameter of the hole required for this is 20 mm. Insert the temperature and humidity probe into the bushing, position the data logger in the display cabinet base and connect it to the probe. The sensitive micro-climate inside the display cabinet remains unaffected thanks to the O-ring seal in the display cabinet bushing.
