Usage Precautions:
- Purpose: Temperature measurement and control.
- Avoid current flow that causes self-heating and measurement errors.
- When soldering with a soldering iron, the welding point should be at least 2mm away from the glass bulb. Soldering temperature should be below 360, and soldering time should be less than 3 seconds.
- If the lead wire is bent, the bending point should be more than 2mm away from the glass bulb to prevent damage.
- Storage Temperature: -10 ~ 40.
- Storage Humidity: 75% RH.
- Avoid storage in environments with corrosive gases and direct sunlight.
- Reseal packaging after opening.
