Water Quality Sensors

Hydrolab Depth

The Hydrolab Depth Sensor is a high accuracy, pressure based sensor designed to provide reliable water depth and level measurements in professional water quality monitoring applications. Accurate depth data is essential for understanding water column dynamics, tracking water level changes, and supporting correct interpretation of other water quality parameters measured by multiparameter sondes.

Factory integrated into the Hydrolab HL4 and Hydrolab HL7 water quality meters, the Hydrolab Depth sensor delivers stable and repeatable measurements in rivers, lakes, reservoirs, groundwater systems, and coastal environments. Its robust design ensures dependable performance in both short-term field surveys and long-term unattended monitoring deployments.

SENSOR COMPATIBILITY 

The Hydrolab Depth Sensor is factory integrated into the following Hydrolab water quality meters:

• Hydrolab HL4
• Hydrolab HL7

Factory integration ensures seamless communication with the sonde, reliable data logging, and accurate depth measurement alongside other water quality parameters.

WHY MEASURE DEPTH?

Water depth is a fundamental parameter for understanding hydrological conditions and water quality dynamics. Accurate depth measurements allow users to assess changes in water level, calculate flow or volume, and correctly interpret vertical profiles of temperature, dissolved oxygen, conductivity, and other parameters.

The Hydrolab Depth Sensor provides reliable depth data that supports environmental monitoring, flood assessment, groundwater studies, and long-term water level monitoring programs. When combined with other Hydrolab sensors, depth measurement adds essential context to multiparameter water quality data.

IMPORTANT

Note: The Hydrolab Depth Sensor is supplied as a factory-integrated accessory and cannot be purchased as a standalone product.
