CTD Diver

CTD Diver

Overview

Water CTD Diver

Traditionally frequent monitoring of soil and groundwater quality has been a very labour-intensive task. This is specially true where saltwater intrusion or pollution at remediation sites needs to be monitored.

The answer is here!

The new CTD Diver now sets the standard for reliability and longevity in groundwater quality monitoring. The CTD Diver is a fully stand-alone datalogger with built-in memory, battery and sensors. The CTD’s ceramic casing and unparalleled conductivity measuring range (0-120 mS/cm) make the CTD-Diver suitable for use at every measuring site.

The CTD-Diver is impervious to the most aggressive substances found in water environments. Its ceramic casing resists corrosion where even the strongest metals yield. It is a highly reliable, compact datalogger for the simultaneous measuring of groundwater level, temperature and conductivity.

Level, temperature and conductivity are measured at time intervals predetermined by the user. The measured values are stored in the datalogger’s memory and can be read out at any given time.
