Description
1. The temperature measurement standard deviation is 0.2mK, and the long-term drift over a 24-hour period is less than 1 mK.
2. The temperature control stability is ±0.001°C.（which depends on the controlled object and parameters, meeting the stringent precision temperature control requirements for most applications, including those of semiconductor laser devices.)
3. Both bipolar and unipolar output modes are selectable options.
4. It allows for limiting the maximum rate of temperature change.
5. Supports the use of NTC (Negative Temperature Coefficient) thermistor temperature sensors.
6. Features a chip-scale design that facilitates integration into circuit board designs.
7. Incorporates an overheat protection function for the circuit board, ensuring reliable performance.
8. Offers a screen-display control module that allows direct parameter setting, with power-off memory for set data, making it convenient for production line workers.
9. Provides a complete set of serial communication control commands, offering an open platform for customization and interfacing.
10. Giving away computer software.
