The CTDP 300 is a multi-parameter conductivity, temperature, ceramic pressure and pH sensors. Field proven gel-filled double junction pH electrode, toroidal conductivity measurement that eliminates electrode corrosion effects and depth readings regardless of atmospheric changes guarantees long-term performance and highly accurate temperature compensated measurements. The CTDP 300 includes internal data logging and features RS 232 output.
The Stevens-Greenspan Conductivity/ Temperature/Pressure/pH Sensor provides the accuracy and reliability required for a wide range of demanding measuring applications.
With state of the art ceramic pressure and toroidal conductivity measurement technologies the Stevens-Greenspan CTDP300 Sensor guarantees long term performance and highly accurate temperature compensated measurements in the harshest of environments.
Make more accurate electrical conductivity, temperature, pressure and pH measurements with Stevens-Greenspan’s state of the art CTDP300 sensor
The Stevens-Greenspan CTDP300 Sensor combines robust, sealed construction with a combination of high performance sensor technology to offer unparalleled reliability. The high reliability of Stevens-Greenspan sensors means critical measurements are not lost through sensor down time. Time wasting unscheduled site visits are therefore minimized.
Toroidal conductivity sensing technology substantially eliminates inaccuracy in conductivity measurements due to temperature and electrode effects. Accuracy in pressure measurement is ensured through the use of a large-faced gold plated ceramic pressure sensor — a technology known for its long term repeatability — supplemented by microprocessor controlled electronics which maintain near perfect linearity (0.02%) and low temperature drift (0.002% /°C) over a wide depth range. The gel-filled double junction pH electrode with optically isolated signal conditioning electronics provides long term accuracy in pH measurements. Onboard microprocessor compensation substantially reduces system non-linearity and temperature drift errors.
Stevens-Greenspan’s intelligent Conductivity/Temperature/ Pressure/pH Sensor model CTDP300 is a complete, self-contained conductivity, pressure, temperature and pH measurement and data logging system. The CTDP300 provides sophisticated and versatile data acquisition, control and communications capabilities. Standard features include:
A separate data logger and weatherproof housing are not required, eliminating the added deployment costs normally associated with providing a remote data logging capability.
Sophisticated communication features in the CTDP300 make remote site logging of key water parameters easier than ever. In combination with an external data modem and mobile phone, the CTDP300 enables remote uploading of logged data and reprogramming of logging schedules. In addition the CTDP300 can respond to user-programmed alarm conditions by triggering an associated sensor or by calling one of four preset phone numbers with a user-programmed alarm message.
The CTDP300 can be powered using external batteries (via the sensor cable) or with Stevens-Greenspan’s optional lithium battery pack, which can be fitted as an extension to the sensor body, making a fully self-contained measurement and logging system.
The CTDP300 also provides a supplementary rain gage input. With the addition of a tipping bucket rain gage, the CTDP300 becomes a completely self-contained hydrographic measuring station, enabling correlation of rainfall and river height data from one compact monitoring package.
