Part No.

SEN461

Detect temperature of the object and medium which thermocouple is contacted.

This equipment is used to detect temperature of the object and medium which thermocouple is contacted. It can be connected to two thermocouples for testing.

LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other communication methods, LoRa spread spectrum modulation method greatly increases to expand the communication distance.

Widely used in long-distance, low-data wireless communications. For example, automatic meter reading, building automation equipment, wireless security systems, industrial monitoring. Main features include small size, low power consumption, transmission distance, anti-interference ability and so on.
