The Extech TM100 Type J/K Single Input Thermometer can measure temperatures ranging from -200°C to 1372°C (-328°F to 2501°F) for Type K and -210°C to 1100°C (-346°F to 2012°F) for Type J. It boasts a high resolution of 1°C/0.1°F and a huge backlit LCD display with readouts in °C, °F, and Kelvin. The data hold function freezes the reading on the display and displays the maximum, minimum, and average. Readings provide a relative time stamp. In addition, the offset key is used for the zero function, which allows for relative measurements. It includes an auto power off and disable capability. This thermometer comes with a Type K bead wire temperature probe and three (3) AAA 1.5V batteries.
