DTR-20 Isothermal Blackbody Calibration Source
With isothermal cavity, the DTR-20 is a portable blackbody calibration source utilizing a digital indicating temperature ambient 20℃ to 50℃ (68F to 122F). The 80 mm diameter end closed tube is heated or cooled with an internal solid state thermoelectric heat pump. It has a built-in digital temperature controller to provide accurate, stable temperature as well as to provide readout.
