Product features: built-in microprocessor. The detector stores and judges the data collected by itself, and has the function of self-diagnosis and constant temperature alarm. The detector can be set to alarm at a fixed temperature (60 or 70 degrees Celsius); the output temperature rise and fall curve. The temperature rise curve can be seen through the controller, which has high stability. Dust resistance, electromagnetic interference resistance, corrosion resistance, environmental temperature impact resistance; moisture resistance, can adapt to the requirements of different climatic environments.
