CTD100

Conductivity – Temperature – Depth Sensor

CTD100 is a pressure-type hydrological and water quality measuring instrument with good stability, high precision, low power consumption, small size and full functions.
The product uses a high-precision and highstability pressure sensor as the pressure sensing element. The output data undergoes
internal intelligent linear correction and temperature compensation, which meets the demand for high precision and high stability of the product. It is suitable for measuring seawater and fresh water, surface water, groundwater and in marine environments.

The electroconductivty measurement uses four-electrode technology. Compared with the traditional two-electrode conductivity sensor, it has higher accuracy, wider measurement
range and excellent stability.

The four-electrode conductivity sensor completely solves the polarization problem in high conductivity test; it also solves the problem of inaccurate readings caused by electrode contamination.
