For easy and quick temperature measurement without touching the object, the wavelength of the radiation is below the red range of visible light and is therefore called "infrared." The housing is made of plastic and is suitable for monitoring climate and heating systems, beverages such as wine, and pools. The battery is a CR 2032 coin cell. The accuracy is ± 1°C or 1% from 15° to 40°C, the reproducibility is ± 1°C or 1%, and the display resolution is 0.1°C. The response time is approximately 500 ms, and the operating temperature is at 0. The dimensions are 68 x 37 x 18 mm.
