The IP67 rating provides a high level of protection against dust and water. The number 6 means that the thermal imager is completely dustproof, which means complete protection against the ingress of dust. Number 7 means that the device is protected against immersion in water up to 1 meter deep for up to 30 minutes. IP67 rated thermal imaging cameras are ideal for extreme conditions, such as industrial applications, rescue operations or in the field where maximum resistance to the elements is required.
