The TASI TA612 Series Multi-Channel Thermocouple Thermometers are professional temperature measurement instruments designed for industrial testing and monitoring applications. Also known as digital thermocouple thermometers, industrial temperature testers, multi-channel temperature meters and temperature data loggers, the series includes TA612A single-channel, TA612B dual-channel and TA612C four-channel models. Supporting K, J and T type thermocouples, these instruments provide accurate multi-point temperature measurement for industrial, laboratory and maintenance applications. Featuring a high-precision temperature acquisition circuit, the TA612 Series delivers stable and reliable temperature measurements with temperature difference calculation between channels. With various thermocouple probes, it can measure surface, liquid, air and internal equipment temperatures, making it suitable for mechanical manufacturing, heat treatment, mold processing, plastic molding, electronics production, PCB testing, motor inspection and transformer temperature monitoring. The built-in data logging function allows users to record temperature changes over time. Through USB communication, measurement data can be transferred to a computer for real-time monitoring, temperature curve analysis and report generation. Additional functions including high/low temperature alarms, MAX/MIN recording and data hold improve testing efficiency and support professional temperature analysis. The TA612 Series is widely used in HVAC systems, refrigeration equipment, food processing, cold chain storage, automotive maintenance, battery testing, research laboratories and industrial automation. With multi-channel measurement capability, flexible thermocouple compatibility, reliable data recording and portable design, the TA612 Series provides an efficient temperature measurement solution for engineers, technicians and quality professionals.
