Thermometer reads from ‚Äì328 to 2498°F and ‚Äì200 to 1370°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. Unit features HOLD button that freezes display to capture current reading. Batteries power unit for 1 year of routine use. Total-Range Thermometer is one of the most technically advanced, fastest-reading, yet easy-to-use thermometers ever designed. A microprocessor updates the display twice a second. Rugged unit is constructed of shock-resistant ABS plastic. Water-resistant case stops dirt, dust, fumes, and water‚Äî perfect for use in lab or plant's worst environment. Meter only accuracy: ¬±1°C between ‚Äì50°C to 740°C, otherwise ¬±2°C. Uses all Type-K thermocouple probes. At the touch of a button, recall minimum and maximum temperature readings captured during any time. Alarm function may be set in 1° increments. Alarm sounds when the temperature rises above or falls below high/low set points. Count up timer alarm may be set from 23 hours 59 minutes to 1 minute. Sound signals when time is reached. Back-lighting button permits reading in dark areas. 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).
