By using a unique seismic A/D converter, suspended objects in harsh environments can be quickly and stably measured. Adopting intelligent intermittent transmission method and low-energy design, as well as battery over discharge protection circuit, automatic power saving function, and percentage display of battery level, it is easy to choose the appropriate charging timing, avoiding battery damage and shortened service life caused by over discharge. Multiple ways of automatic accumulation, unique human-machine dialogue function, convenient operation and input. A perpetual calendar clock that is not affected by interruptions, even when printing weighing data. The weighing data can be communicated with a computer through a standard RS232 interface or displayed on an external large screen. This series is widely used in measuring occasions such as mining enterprises, warehouses, and docks.
