Edaphic Scientific Soil Oxygen Sensor

Request Quote

The MIJ-03 Soil Oxygen Sensor is designed for long-term, monitoring of soil or sediment oxygen concentration. Each sensor is individually calibrated for maximum accuracy. Calibration is extremely easy and can be completed in ambient air.

Maintenance of the MIJ-03 Soil Oxygen Sensor is minimal. Once the sensor is installed in the soil, there is no further maintenance. The life-time of the sensor is approximately 5 years when the electrochemical element of the sensor expires.

The MIJ-03 Soil Oxygen Sensor has a voltage output that can be supported by any compatible data logging system. The Edaphic Scientific range of ES-SYS data logging systems, with internet access, can support the MIJ-03 Soil Oxygen Sensor. Or, our scientists and engineers can assist you in connecting the sensor to your existing system.

The MIJ-03 is built from a polyoxymethylene (POM), a rigid thermoplastic, that provides long-term stability in harsh environmental conditions. The sensing apparatus is behind a Teflon hydrophobic, gas porous membrane, meaning the MIJ-03 can measure under saturated, flooded and anaerobic conditions. Rainfall and irrigation are no problems for the MIJ-03 Soil Oxygen Sensor.

Measurement Principle

The MIJ-03 Soil Oxygen Sensor is an electrochemical, or galvanic, style sensor. Similar to the operation of a battery, an electrochemical difference is created which is proportion to oxygen concentration. Oxygen molecules diffuse through the Teflon membrane, via gradients of diffusion, and interact with the electrolyte in the sensor's cell. An electrical charge is created between the anode and cathode of the cell. The greater the oxygen concentration, then the greater the electrical charge. The relationship between the oxygen concentration and the electrical charge is linear. A two-point calibration curve: ambient air (20.9%) and 0% oxygen. Fortunately, the MIJ-03 Soil Oxygen Sensor is extremely easy to calibrate: ambient air can be easily measured; and the 0% value is simply 0mV in the sensor. Therefore, the MIJ-03 sensor can be calibrated in ambient air.

Eijkelkamp Granular Composition Test Set

Request Quote

Granular composition test set, complete with electromagnetic sieve shaker and standard set of sieves for dry and wet sieving. Suitable for the determination of the particle size distribution of soil samples.

Particle size distribution determination with our granular composition test set helps to classify the soils on the basis of international standards. The set contains:

• Electromagnetic sieve shaker that can hold up to 8 sieves
• Set of stainless-steel wire mesh sieves of 200 mm diameter, with different apertures

The electromagnetic sieve shaker keeps the sample in continuous motion, for the best possible sieving results and accurate determination of the granular composition. The sieve shaker and the stainless steel mesh sieves (including receivers and lids) are suitable for both wet and dry sieving.

Outstanding Features

• Suitable for wet and dry sieving
• Determine particle size distribution
• Continuous motion for best sieving results
• Complete set to analyse coarse fractions of soil samples

---

Note: The granular composition test set is used to analyse coarse fractions of soil samples. To perform a complete analysis or the grain-size of soil samples, the hydrometer set, for smaller fractions, is needed as well.

Eijkelkamp Penetrologger with GPS and Soil Moisture Probe

Request Quote

 

The Royal Eijkelkamp penetrologger is a versatile instrument for in-situ measurement of soil penetration resistance. This electronic penetrometer comes with a built-in datalogger and memory for up to 1500 measurements.

This lightweight penetrologger of Royal Eijkelkamp is ergonomically designed and can measure up to a depth of 31.4 inch (80 cm). The penetrologger is used to measure the penetration resistance of the soil. The penetration resistance is a means to determine the carrying capacity of the soil and the ease with which roots can grow through the soil. This is important in agricultural, farming, and civil engineering techniques.

With the built-in data logger, the data is easily stored for further processing on your PC. The penetrologger contains an accurate internal GPS system (16 channels GPS receiver) to determine the exact measuring location. The coordinates stored in the penetrologger can be linked to a location or map using software (or less accurately via the Internet). The penetrologger results are displayed in MegaPascals (MPa) and Newtons (N) as a function of depth. The penetrologger also derives the Cone Index (CI).

Outstanding Features

• Incorporated fast GPS, data is auto-stored
• Traffic ability or load bearing capacity research
• No mechanical parts, strong and reliable
• Numerous different projects can be defined
• Geotechnical soil research

Applications

• Agricultural- as well as the civil engineering sector and technical soil research
• General soil science research
• Trafficability or load bearing capacity research
• Foundation technology
• The detection of compacted (possibly impermeable) sub-soil layers
• Checking whether or not the soil is suitable for agricultural use
