The CT2X water conductivity logger is a submersible conductivity / temperature sensor with an integral water level/depth datalogger. A 4-pole epoxy / graphite electrode cell is incorporated making it perfect for rugged field applications. Fringe field interference errors are reduced, inaccuracy caused by polarization effects is decreased and contact resistance problems are reduced by this technology.
Over 349,000 records of conductivity, temperature, depth and time data can be stored with the non volatile memory.
It has a slim 0.75” diameter and a 316 Stainless Steel, Viton and PTFE/FEP. Titanium is available on request.
The water conductivity logger is powered by two internal AA batteries or can be powered by an external auxiliary power supply for data intensive or SDI-12 applications.
The CT2X CTD logger can be easily networked with other Smart Sensors with the industry standard RS485. Modbus and SDI-12 protocols are available which makes ideal for the Adcon telemetry system.
Aqua4Plus software, gives the user extensive control, flexible programming and real time monitoring. The data can then be easily exported to spreadsheets and databases.
The CT2X water conductivity logger is available with or without cable. Choices of polyurethane, polythene and PTFE/FEP are available. Unlike some manufacturers you are not charged the earth for connectors and cable!
