Associated Sensors

ICT02

The ICT02 Soil Oxygen Sensor performs measurements based on a Galvanic cell principal. It is a passive sensor and does not require voltage input. The sensor has an automatic temperature compensation via an in-built thermocouple compensation circuit.

• Geo, Civil and Environmental Engineering
• Hydrology Management
• Mine Site, Land Fill, Road & Railway Monitoring
• Plant Canopy Monitoring

Geotechnical Engineers

The ICTO2 Soil Oxygen Sensor is not affected by saline or sodic soils and can be used in wide ranging applications. For example, in the mining and landfill industries the sensors could be buried in wastes to aid assessment of the effectiveness of covers designed to reduce oxygen flux into the waste.

Plant Physiologists

Plant species vary in their tolerance to anaerobic and oxygen deprived soils. The Soil Oxygen Meter can quantify the exact level of tolerance for all plant species. Plant root systems uptake oxygen to support respiration and other energy requirements. Figure 4 shows a correlation between photosynthetically active radiation (PAR) and soil oxygen where a noticeable decrease in soil oxygen content occurs during the day. With additional measurements this decrease in oxygen content can be related to plant or microbe activity. The formation of aerenchyma in plant roots is a common morphological response to decreased oxygen in soils. The Soil Oxygen Meter can be used to quantify the level of soil oxygen content whereby this occurs for individual plants.

Soil Oxygen Meter (SOM)

• The SOM is a stand-alone instrument and does not require extensive cables and power requirements. All data is stored within the unit on a removable SD card.
• Communication with the SOM is made either with a USB or wireless connection. Wireless is compatible up to 250m distance.
• In conjunction with an ICT web-based controller, the SOM and/or individual sensors can be controlled remotely. Realtime, live measurements can be made remotely from any location with internet access. Data can be logged directly onto a remote computer or stored in the field on an ICT log server which can then be accessed via the internet.
• The SOM has a Windows configuration software. The software is GUI based and extremely user-friendly. Custom calibration equations or data can be entered and edited via the software. Real-time measurements, diagnostics and sensor configuration can easily be made.
• The SOM has 2 wire, non-polarized bus for power input and data. Because the SOM is non-polarized there is no chance of incorrect wiring of positive and negative voltage.
• ICT International can offer to assist with defining objectives of measurement programs, developing a plan for measurement and interpreting data.

Overview

ICT International instruments have customised software support. The software acts as an interface between the user, instrument and sensors. Each instrument has software pre-configured for the sensors it supports.

Look up Table

A look-up table is a linear conversion from a mV output from the sensor into any conversion units. A minimum of two values are needed: the lowest mV output and the highest mV output.

Script

For more complex conversions, such as exponential, logistic or polynomial equations, users can enter a script.

Self Calibration

Individual sensors can be calibrated using the ICT International software. A minimum three point calibration curve is required. Statistical analysis of calibrated data is automatically performed. Calibration curves can be saved, retained and modified. Calibration of individual sensors allows absolute precision data collection.

Communication

MCC

• Wireless communication with any ICT International instrument within 250m.
• Portable, easy to use via ICT International software interface.
• Connects directly into any Windows based computer via USB cable.
• Multiple channel ports, such as SDI-12, RS232, RS485, SI8, ICT-BUS & ICT Wireless Protocols, for highly flexible interfacing between ICT International instruments and third party devices.

ICT Instrument The ICT Instrument is pre-calibrated and can support up to ten sensors.
Breakout board Sensors, connect to the meter via a Pelican box for maximum environmental protection. Depending on sensor requirements, a maximum of 5 or 10 sensors can be connected.
Windows configuration software Custom calibration equations or data can be entered and edited via the software. Real-time measurements, diagnostics and sensor configuration can easily be made.
USB cable
Removable Micro SD card plus adapter Data stored internally on a 2GB removable micro-SD card. Memory can handle months to years of data. Expandable to 4GB, 8GB or 16 GB micro-SD cards.
Solar panel / CH7 Power Supply (optional) Field Applications: 7W Solar Panel (standard) 11W Solar Panel (high demand) 12V Battery (recommended, not supplied) Solar charger regulator (recommended with solar panel) Laboratory / Glasshouse Applications: CH7, 12V Switch-mode power adapter (Note: must be 12V power input)
MCC Wireless Device (optional) Communication with the meter is made either with a USB or wireless (MCC) connection. Wireless is compatible up to 250m distance.

Individual Calibration of Sensors

Calibration of the sensors is carried out using the ICT Instrumentation Software provided free with the ICT Data Logger. If your computer is connected to the internet the software will automatically check for any updates when you run the program. Connect your computer to the logger using the methods described in the manual provided, and start the ICT Instrument Software.
