The device is able to measure the temperature of the liquid/vapors and the surface temperature of a solid object, with a considerably wider measuring range. Suitable for both high-temperature fields of blast furnace, cookery, low temperature measuring for liquefied gases, etc. Digital Thermometer Thermocouple Packed with two K-Type thermocouples, this professional thermometer can direct measure the temperature of tested object. Support Two K- Type Thermocouples K/J/T/E/R/S/N Type. Also, support other types of thermocouples, J/T/E/N/R-type. Features: High accuracy: due to direct contact with the measured without intermediary which effects the final output. User ergonomics. It is easy and fast for user to use with simple key operation mode and comfortable hand feeling. Low battery indication, auto power off. Large LCD backlight display, data hold. Max min and average value display. High accuracy Measure the thermocouple of J, K, and T, E, N, S and R type °C/°F selectable Human-centered design Double display with backlight Shows T1/T2 and combination of T1 and T2 Data hold Auto power off Max/Min/Average value measurement Dual channel input Electrical compensation function Specifications: Main Unit Measuring range: J-type: -210 ~ 1200°C (-346 ~ 2192°F) K-type: -200 ~ 1372°C (-328 ~ 2501°F) T-type: -250 ~ 400°C (-418 ~ 752°F) E-type: -150 ~ 1000°C (-238 ~ 1832°F) N-type: -200 ~ 1300°C (-328 ~ 2372°F) R-and S-type: 0 ~ 1767°C (32 ~ 3212°F) Resolution: 0.1°C/°F <1000° 1°C/°F =1000° Accuracy: ±0.1%+0.6°C Input: Bi-channel input Operating Temperature: 0~40°C Storage Temperature: -10 ~ 50°C; 20~90% RH (humidity) Power supply: 3 x 1.5V AAA batteries Size: 72 x 29 x 145mm Weight: 159g
