The Extech 433201A (115V) or 433202A (220V) Microprocessor Thermocouple Calibrator/Thermometer is a precision electronic instrument that can be used for calibrating and measuring thermocouples.
The Extech 433201A/433202A is a microprocessor-based thermocouple calibrator and thermometer designed for measuring and generating millivolt signals. It features two primary modes: Measurement mode, which accepts input from a thermocouple to display temperature or millivolts with an adjustable offset feature, and Source mode, which outputs a precise millivolt signal to external devices based on selected thermocouple types.
The device supports multiple thermocouple types including J, K, T, E, C, R, S, and N. Users can select the desired unit of measure (°C or °F) or display values in millivolts. The instrument includes five memory locations for preset output values to facilitate easy recall during calibration tasks.
