Thermocouple thermometer body ranges from -50℃ to 1300℃ (-58℉ to 2372℉) and contains two thermocouples, which can measure -50 to 500 degrees Celsius (-58 to 932 degrees Fahrenheit). Support ℃, ℉, K temperature modes to meet your various measurement needs. K-type thermocouple is equipped with "T1-T2" calculation function, which can measure the temperature difference between two samples with a reading accuracy of 0.1-0.4℃. In addition, this thermocouple also has MAX/MIN/AVG, data hold, automatic shutdown functions, making your measurement work more efficient and convenient. Thermocouple thermometer is battery-powered, portable, built-in folding frame, with only 6 simple buttons, suitable for beginners, engineers, scientific researchers, laboratory technicians, factories, hospitals, homes, etc. Our thermometers are made of materials to reliable performance in various working environments. The body is protected by a removable silicone rubber to prevent accidental drops and shocks and extend service life. The AC thermometer is suitable for high temperature measurements in stainless steel, ovens, furnaces, ceramics, molten metals and other industries.
