Introduction
The M310-HT is a portable blackbody calibration source utilizing a digital indicating
temperature controller that may be set to any temperature between ambient temperature to
450 °C (842 °F). 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 /- 0.1 °C. The blackbody
emitter mechanism uses a resistive heating device that provides long life, short stabilization
times and stable temperature control.
Temperature setpoints are altered simply by pressing the

arrow buttons on the controller.
The lower display is the setpoint and the upper display is the actual blackbody emitter
temperature.
