DTM-B Portable Blackbody Radiation Source (RT+10 ~ 550℃）
A blackbody radiation source is an essential standard device used in infrared calibration, precision temperature measurement, and related scientific and industrial applications. It provides a stable and highly accurate reference for calibrating infrared thermometers, thermal imagers, and other non-contact temperature measurement instruments. Owing to its excellent precision, stability, and adaptability, it is widely employed in calibration laboratories, industrial quality control, and scientific research environments.
Full-range resolution of 0.01 °C: Selectable in three levels: 0.01 °C, 0.1 °C, and 1 °C.
6- to 10-point temperature calibration and correction： Automatically performs linear fitting between set value (SV) and process value (PV) to ensure accurate temperature control.
Capacitive touchscreen： Smart human-machine interface with multi-window display.
Adjustable heating rate： Supports uniform ramp-up based on user-defined values for smooth and controlled temperature transitions.
Stability indicator： Real-time operation data display for intuitive system monitoring.
Bilingual interface： Switchable between Chinese and English for international use.
Over-temperature protection： Dual protection via hardware and software.
Communication options： Supports USB, Wi-Fi, WLAN, and RS-232 serial communication.
Temperature unit switching： Supports °C, °F, and Kelvin.
Mobile App control： Enables remote control and real-time monitoring via smartphone.
