The RayTemp®3 infrared thermometer measures temperature over the range of -60 to 500℃ with an assured accuracy of ±1℃ over the critical food range of 0 to 65℃, outside of this range it's ±2% of the reading or whichever is greater in an ambient temperature of between 15℃ and 25℃, with a repeatability of ±1℃ of reading. It incorporates a clear, easy to read, LCD display with low battery, laser and backlight indication and an auto power off facility that turns the instrument off after 15 seconds, maximising battery life. It is ideal for measuring food surface temperatures, eliminating the need to touch or contaminate the food you are measuring, avoiding the risk of cross-contamination. The unit can be used by anyone as there is no need to focus or adjust the instrument. It features a single push button, allowing the user to select ℃ or ℉. The thermometer also incorporates a circular laser, which allows you to precisely target the diameter of the area to be measured. As you move closer or further from the target the laser circle changes diameter. The unit incorporates a 12:1 optic ratio (target distance/diameter ratio) and a fixed emissivity of 0.97 making it more suitable for chilled and frozen foods, although it can be used for a wide range of other applications, swimming pools for example.
