Multi-parameter water quality analyzer
The device adopts an imported sensor core that converts liquid level pressure signals into corresponding digital signals. These are processed by digital circuits and output as a standard two-wire RS485 signal. The integrated design encapsulates the isolated sensor and digital processing circuit within the probe, directly outputting RS485 signals via a specialized cable.
