Details
The M340 is a portable blackbody calibration source utilizing a digital indicating temperature controller that may be set to any temperature between -20 °C to 150 °C (-4 °F to 300 °F). The thermoelectric heating/cooling mechanism is utilized to achieve a compact and easy-to-use blackbody source.
A precision RTD temperature sensor is embedded in the blackbody emitter providing high accuracy and repeatability. The temperature controller uses the industry standard PID algorithms to control the emitter temperature to within +/-0.1 °C. The blackbody emitter mechanism uses a solid state thermoelectric heating and cooling device that provides long life, short stabilization times and stable temperature control. The most important features of the M340 is the ability to achieve temperatures below ambient (cooling) and the fast response times between temperature set points.
Temperature set points are altered simply by pressing the up or down arrow buttons on the controller. The lower display (green) is the set point and the upper display (red) is the actual blackbody emitter temperature.
