MCR series loggers are 4-channel battery operated loggers. The MCR-4TC is a temperature logger equipped with a thermocouple sensor which can measure from -270℃ to 1760℃. With multi channels and a large internal memory (up to 960,000 readings per unit), the MCR-4TC is perfect for measuring temperature, especially extreme temperature, at various spots for long periods of time. Moreover, by using an SD card and the "Auto Data Export" feature recording can be carried out, even when using short recording intervals, over longer extended periods of time. Note: We do not stock thermocouple sensors; please purchase a compatible sensor. Auto Data Export to SD Memory Card
