Product description:
SP546SD is a true digital single-point load cell with an accuracy of C6. The built-in microprocessor actively monitors environmental changes, continuously compensates for various performances in real time, and indicates the parameter status of each load cell, ensuring the weighing result more accurate and stable. The hermetically sealing process ensures high sealing performance and can work normally in harsh industrial environments.
