Description
1. Temperature measurement standard deviation is 0.2mK, with a long-term drift of less than 1 mK over a 24-hour period.
2. Temperature control stability ranges from ±0.001 to ±0.01°C.（which varies depending on the controlled object and parameters. This level of precision can meet the stringent requirements of most scenarios, including the demanding temperature control needs of semiconductor laser devices.）
3. Users have the option to select either bipolar or unipolar output modes.
4. The ability to limit the maximum rate of temperature change is available.
5. Supports the use of Negative Temperature Coefficient (NTC) thermistor temperature sensors.
6. Capable of handling high-power outputs, with support for up to 24V and 15A per channel.
7. Equipped with a circuit board overheat protection feature, ensuring reliable performance.
8. Comes with a screen display control module allowing for direct parameter setup, with power-loss memory for set data, making it convenient for production line workers.
9. Offers a full suite of serial port control commands, providing an open-platform solution.
10. Giving away computer software.
