What is the reason for the large temperature fluctuations in the low temperature tank (low temperature instrument) of the impact sample?

The impact sample cryostat, also known as the impact test cryostat, constant temperature cryostat, etc., is a refrigeration device for cooling and heat preservation of the sample in the metal low-temperature impact test. The CDW series impact cryostat is easy to operate and has high working efficiency. However, no device can guarantee zero failure forever. After the device has been used for many years, if the temperature fluctuation becomes larger and exceeds the original temperature range, how to operate?
Based on experience, the following reasons and solutions are summarized for your reference:
1. Too little ethanol in the tank. In this case, you need to add alcohol again.
2. The stirring failed to work normally. It is necessary to check whether the stirring is turned on. If the circuit is normal, the stirring motor needs to be replaced.
3. The PID parameters of the temperature control meter are incorrect. In this case, self-tuning needs to be re-tuned. If not, you can contact the manufacturer at any time and let the manufacturer's staff assist in the setting.
