Usage Precautions

Primary Use: Temperature measurement and control.
Measurement Accuracy: Avoid current flow through the thermistor that causes self-heating, as this can lead to measurement errors.
Soldering: When using a soldering iron, maintain a distance of at least 2mm from the coating layer. Welding temperature should be below 300, and welding time should be less than 3 seconds.
Storage Conditions: Store at temperatures between -10 and 40, with humidity 75% RH.
Environmental Avoidance: Do not store in environments with corrosive gases or direct sunlight.
Packaging: Reseal packaging after opening if not fully used.
