Greenspan manufacture 3 types of Electrical Conductivity Sensors. The Greenspan Electrical Conductivity Sensor EC250 offers an excellent combination of advanced features. The toroidal sensing technology eliminates electrode corrosion effects, guaranteeing long life and reduced field servicing. This sensor can be field calibrated with Greenspan’s easy to use calibration software. The EC250 provides temperature measurement as well. The sensor contains a microprocessor, which controls temperature compensation and linearisation, to ensure highly accurate readings in demanding conditions. Separate conductivity and temperature outputs deliver raw conductivity or on-board normalization of conductivity at 25˚C. The EC250 is available with either a delrin (plastic) or 316 stainless steel body and can be supplied in a variety of ranges. |
Oxygen Sensor
The OxyGuard Model 525 is specially designed for use with data loggers in the field. It combines an OxyGuard dissolved oxygen probe and a transmitter with voltage output. It can be used to measure dissolved oxygen as well as oxygen in the air or other gas.

The power consumption and minimum operating voltage are low, enabling it to be powered by solar panel sources. The standard output is 0-2.5V, the input signal requirement for many data loggers, but the 525 can be delivered with other output voltages on request.
A whole series of outstanding specifications ensure accurate, trouble free measurements under all conditions and no matter how long the connections are.
A special feature of the 525 is a fast warm-up time to enable the use of effective power saving. |
