CT2X Cableless Conductivity Level Temperature Logger

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

The AquiStar CT2X is a submersible conductivity level and temperature sensor with built-in datalogging. This device stores over 100,000 records of conductivity, level, temperature, and time data, operates with low power, and features easy to use software with powerful features. The CT2X is also available with a pressure/temperature module, giving added functionality in the same sensor housing.

CT2X Conductivity Level Temperature Logger

The CT2X incorporates 4-pole electrode cell measurement technology. This technology reduces fringe field interference errors, lessens inaccuracy caused by polarisation effects, and lowers contact resistance problems. Four-pole electrode technology also allows users to work with one electrode over a wide range of conductivity.The conductivity probe is constructed of epoxy/graphite, making it extremely durable for use in rugged field conditions. To clean, simply scrub with a small brush.

FEATURES
• RS485/RS232 interface
• Also measures TDS in mg/L
• 100,000+ records / non-volatile
• Linear and nLFn temperature compensation
• Small diameter (0.75")
• Conductivity, temperature & time with pressure/temperature option
• 10 microSiemens/cm to 100,000 microSiemens/cm
• 316 stainless steel, Viton and Teflon construction
• Polyethylene, polyurethane and FEP Teflon cable options
• MODBUS protocol for RTU & PLC applications
• Easy export to spreadsheets & databases

OPERATION
The CT2X is powered internally with one 3-volt lithium battery or with an external auxiliary power supply for data intensive applications. Works on alkaline, rechargeable, and other auxiliary power systems.

The CT2X comes with powerful, easy-to-use, Windows based Aqua4Plus software,affording the user extensive control, including real time monitoring, flexible programming, easy field calibration, and both tabular and graphic data displays.

Aqua4Plus offers easy, one-point calibration. Simply put the probe in the desired standard, and then use the built-in field calibration utility to adjust to the correct conductivity output.

Linear and non-linear temperature compensation features add flexibility to this sensor. The user can enter specific linear temperature coefficients to match the material being sampled. Alternately, for natural waters, which do not have linear temperature coefficients, the CT2X has a non-linear natural water mode meeting DIN EN 27888 standards.

Ordering Information:
CT2X Conductivity/Temperature Sensor with Datalogging. 1 MB memory, 0.75” diameter, twist open housing (w/ cable hook-up, waterproof connector, desiccant tube, if needed)

Cabled or Cableless
PSIA = Absolute pressure is zero referenced against a perfect vacuum, so it is equal to gauge pressure plus atmospheric pressure

PSIG = Gauge pressure is zero referenced against ambient air pressure, so it is equal to absolute pressure minus atmospheric pressure. Negative signs are usually omitted.
