Rated IP68, these mice are fully sealed to withstand washdown procedures common in food processing plants. They even have a scroll bar that works the same as a scroll wheel but is sealed to maintain the IP rating. They also resist dirt and dust. Use them in more extreme temperatures than standard office mice, from the high temperatures of a heat-treatment plant to the low temperatures of cold storage rooms. However, they aren’t designed to hold up to impact, drops, or high vibration like our rugged mice.
