CT2X Water Conductivity/Temperature Datalogger
- Conductivity Measurement Range Choice of conductivity measurement ranges - 0 to 100,000, 0 to 200,000 or 0 - 300,000 microSiemens/cm
- Built-In Datalogger Non-volatile memory can store 349,000 records
- Great Flexibility Modbus RTU (RS485) and SDI-12 interface
Overview
The AquiStar CT2X Conductivity Datalogger is a submersible conductivity / temperature sensor with built in datalogger. The CT2X conductivity datalogger is ideal for use in rugged field applications, as it incorporates a 4-pole epoxy/graphite electrode cell. This technology helps reduce fringe field interference errors, decreases inaccuracy caused by polarization effects and lowers contact resistance problems.
The conductivity data logger can store over 349,000 records of conductivity, temperature, and time data and has a non volatile memory which ensures data is not lost in the case of a power failure.
The CT2X is built from 316 Stainless Steel (or Titanium), Viton and PTFE/FEP with a diameter of just 0.75in or 19mm.
The conductivity dataloggers have low power consumption and needs just two AA batteries to power it which can be replaced by the user. Alternatively an external auxiliary power supply can be used for data intensive or SDI-12 applications.
The CT2X electrical conductivity datalogger has a linear and non-linear temperature compensation feature, however specific linear temperature coefficients can be entered to match the material being sampled. A non-linear natural water mode is available for water without linear temperature coefficients.
The CT2X conductivity logger comes with Aqua4Plus software, allowing the user extensive control, flexible programming and real time monitoring, as well as versatile display options. Data can be easily exported to spreadsheets and databases.
The CT2X logger is available with or without cable. Choices of polyurethane, polythene and PTFE/FEP are available.
Other features:
- Modbus and SDI-12 protocols are available
- Measures conductivity, total dissolved solids, salinity and temperature
- Easy networking with RS485
