Moisture meter with non-contact infrared thermometer
View Patent ↗A moisture meter with non-contact temperature measurement capability having a housing, a moisture-detecting device coupled to or contained at least partially in the housing, and having an output related to measured moisture parameters, a non-contact, optically-based temperature sensing device coupled to the housing, having an output related to sensed temperature, an output display contained in the housing, for displaying measurements to a user, and circuitry contained in the housing for processing both the moisture-detecting device output and the non-contact temperature sensing device output, and transmitting the processed outputs to the output display. The moisture-detecting device can be either one or both of a contact-type moisture-detecting device such as a pad on the rear side of the housing, and a pin-type moisture-detecting device in a hand-held probe, and electrically coupled to the circuitry in the housing through a cord.
