CTD-10: Electrical Conductivity, Temperature & Depth Sensor

  • Get Pricing
  • Picture

  • Description

    The METER CTD-10 sensor is a low cost, accurate tool for monitoring of water level, electrical conductivity, and temperature in both ground water and surface water.  The sensor utilizes a vented pressure transducer to obtain accurate water level measurements from 0 to 10 m while removing the effects of barometric pressure.  With a range of 0 to 120 dS/m, the CTD sensor has the ability to make accurate electrical conductivity measurements in a broad range of applications.

    METER’s CTD sensor is a robust, marine grade sensor, 3.4 cm in diameter. It connects by cable to an external data logger. Much of the complex circuitry is in the data logger, lowering the cost of individual sensors without impacting their accuracy or resolution.  This makes it so that instead having to rely on a single measurement, you can measure in several different locations without exceeding your budget.

    The CTD sensor is compatible with all METER EM50 series and Campbell Scientific data loggers. The EM60G offers a remote transmission option to deliver data wirelessly to your desktop. With this option, water depth, temperature, and electrical conductivity can be monitored from any internet-connected computer in near-real time

    Applications

    • Aquifer recharge and recovery
    • Saltwater intrusion, desalination, and wastewater
    • Wetland monitoring
    • Groundwater contamination monitoring
    • Surface water monitoring

    Advantages

    • Robust marine-grade epoxy overmold to resist corrosion in tough environments
    • Compact 3.4 cm diameter sensor body to fit into tight spaces
    • External logger with remote transmission option to deliver data to your desktop
    • Permanent connection allows you to collect data continously without pulling up the sensor
    • Low per-sensor cost

  • Description

    Complete the electrical conductivity picture

    The ES-2 Electrical Conductivity Sensor is designed to measure the electrical conductivity of water in a pipe or tank.  When you pair the new ES-2 with a GS3 or 5TE in the soil, you’ll begin to develop a complete picture of the salts that are going into your system, as well as the salts remaining in your soil or substrate.

    Advantages

    • Continuous EC measurements in a pipe or tank
    • Direct measurements of pore water EC when used in conjunction with the Wetting Front Fullstop
    • Check your EC values anywhere with an internet connection

  • Description

    Simple water pressure sensor

    The PS-1 Irrigation Pressure Switch adds irrigation water on/off data into the soil moisture data set. A useful parameter to add to DataTrac when using soil moisture sensors to monitor irrigation.

    The PS-1 registers ON at 5 PSI (±1.0 PSI). Because the sensor must be plumbed into the irrigation line, your data logger should be located where this can be done conveniently and cleanly.

PT-100 Pressure Gauge

  • Picture

  • Description

    Evaluate system performance

    A sprinkler’s precipitation profile is a function of nozzle size and operating pressure, and each nozzle size has an optimal range of operating pressures. If your system is operating outside this pressure range, odds are your distribution uniformity (DU) is low; some areas are over-irrigated while others are under-irrigated. With the new PT-100 pressure transmitter you can ensure your system is running at the correct operating pressure.
