Digital RS485 CTD Sensor Groundwater Conductivity Temperature Liquid Level Depth Pressure CTD Sensor
>>Overview
The AG-Z100 Digital Groundwater CTD Sensor is a tri-parameter sensor designed to measure water conductivity, temperature, and liquid level depth. Conductivity is measured using the four-electrode method, while liquid level depth is calculated by detecting hydrostatic pressure. Equipped with an automatic cleaning brush, it periodically removes debris from the conductivity electrode and pressure sensor surfaces to ensure measurement accuracy. The sensor adopts a digital and intelligent design philosophy, automatically compensating for fluctuations in light intensity, component aging, and temperature variations. It outputs standardized digital signals directly, enabling network integration and system configuration without requiring an external controller.
