The Habotest HT651D infrared thermometer guarantees unparalleled measurement accuracy. It not only measures the temperature of a specific point, but also the ambient temperature, dew point and relative humidity. The color display makes working with the device easier, and the included K-type thermocouple offers even more options. The thermometer also has an alarm function. Power requires a 9V 6F22 battery, which must be purchased separately.
