- Wide measuring temperature range The thermocouple thermometer main unit ranges from -50 to 1300 C (-58 to 2372 F) and includes 2 Stainless steel K Type Thermocouple Probes that can measure -50 to 500 C (-58 to 932 F). Supports temperature modes C, F, and K to meet your measurement needs. - Function design The K Type thermocouple is equipped with a T1-T2 calculation function to measure the temperature difference between two samples with a reading accuracy of 0.1-0.4 C. In addition, the thermometer provides MAX/MIN/AVG, Data Hold, and automatic power off for efficient and convenient measurements. - Highly mobile and easy to operate Battery-powered and portable, the main unit features a built-in folding frame and only 6 simple buttons with clear usage instructions. Suitable for beginners, engineers, scientific researchers, laboratory technicians, factories, hospitals, families, and other users. - Quality Made of high-quality materials to ensure reliable performance in a variety of working environments. The main unit is protected by a removable silicone rubber holster to prevent accidental drops and shocks and to extend life. - Use scenarios In the laboratory, use the T1-T2 function to compare temperatures between two samples with high reading accuracy for material testing and experiments. In food processing or kitchen environments, monitor surface or component temperatures during cooking or pasteurization to verify safety and quality. In industrial settings or field work, perform quick spot checks on equipment, during metalworking or heat treatment processes, or in hospital and clinical environments to ensure proper temperature control.
