The
Decagon CTD sensor is a low cost, accurate tool for monitoring of water
level, electrical conductivity, and temperature in both ground water
and surface water. The sensor utilizes a vented pressure transducer to
obtain accurate water level measurements from 0 to 3.5 m, while removing
the effects of barometric pressure. With a range of 0 to 120 dS/m, the
CTD sensor has the ability to make accurate electrical conductivity
measurements in a broad range of applications.
Decagon's CTD sensor is a robust, marine grade sensor, 3.4 cm in
diameter. It connects by cable to an external datalogger. Much of the
complex circuitry is in the data logger, lowering the cost of individual
sensors without impacting their accuracy or resolution. This makes it
so that instead having to rely on a single measurement, you can measure
in several different locations without exceeding your budget.
The Em50G offers a remote transmission
option to deliver data wirelessly to your desktop. With this option,
water depth, temperature, and electrical conductivity can be monitored
from any internet-connected computer in near-real time.
