The TC101A is a compact, thermocouple-based temperature data logger. This device is available in three thermocouple connection options: mini plug, screw terminal, and terminal block.

Compatible with eight different types of thermocouple probes, the TC101A can measure temperatures as low as -270 °C, and up to as high as 1820 °C (probe dependent), with an environmental operating temperature range of -40 °C to +80 °C (-40 °F to +176 °F). The TC101A also features a 10-year battery life and a memory storage capacity of up to 838,041 readings.

The TC101A is compatible with the latest MadgeTech 4 Software making starting, stopping, and downloading simple and easy. Graphical, tabular, and summary data is provided for analysis and can be viewed as customizable engineering units.
