Thermometer reads from ‚Äì328 to 2372°F and ‚Äì200 to 1300°C with a resolution of 0.1° and 1°. Switch from °F to °C at the touch of a button. Jumbo-size, 5/8-inch-high digits are readable from 10 feet away. Back-lighting button permits reading in dark areas. Unit features HOLD button that freezes display to capture current reading. Battery powers unit for 1 year of routine use. One of the most technically advanced, fastest-reading, yet easy-to-use thermometers ever designed. A microprocessor updates the display 2.5 times per second. Rugged unit is constructed of shock-resistant ABS plastic. Waterproof design stops dirt, dust, fumes, and water‚Äîperfect for use in lab or plant's worst environment. Supplied rubber boot for probe connector allows the unit to remain waterproof with thermocouple attached. At the touch of a button, recall minimum and maximum temperature readings. Meter only accuracy: ¬±0.3% of the reading plus 1°C between ‚Äì200 to 1000°C, otherwise 0.5% of the reading plus 1°C. Unique differential feature shows the difference in temperature from a set point. Uses all Type-K thermocouple probes. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from the manufacturer's ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Comes ready to use with carrying case, Traceable® Certificate, 9-volt battery, and fast-response, Type-K beaded probe with cable length of 4 feet. Size is 2-2/3 x 7 x 1-1/4 inches and weight is 8 ounces.
