Enabling better global research outcomes in soil, plant & environmental monitoring.

About us

ICT International has been providing solutions for soil, plant and environmental monitoring since 1982.

In the early 1980’s, Dr Peter Cull, having completed his PhD in irrigation monitoring, sought to expand his research and bring together scientific theories with their practical applications especially in soil and plant sciences. For Peter, water was always the key and he believed that developing precision instruments to accurately measure, monitor and understand water would make a significant difference to some of the major challenges in food production and land use. That was thirty years ago. Since then, Peter and his wife Susan have developed ICT International into a highly successful manufacturing and export company providing scientific measuring and monitoring solutions in some of the world’s harshest and most vulnerable environments. Peter, Susan and their team have built on the immense wealth of scientific knowledge to design, develop and manufacture their quantitative monitoring technologies and work collaboratively with leading soil, plant and environmental scientists in Australia and overseas as part of their world-renowned research and development program.


In 2006 ICT International launched an innovation program which produced the company’s first outstanding signature products; the SFM1 Sap Flow Meter and the PSY1 Stem Psychrometer. The SFM1 Sap Flow Meter determines how much water a plant is using and features digital point of measurement data processing to log data. The PSY1 Stem Psychrometer measures the plant’s ability to access water and features the same digital point of measurement data processing, to log changes in the plant water status. ICT International’s instruments are manufactured in Armidale, NSW, and designed and tested in the field. They have been installed to measure plant water use (sap flow), the effects of weather and environmental change in regions across the world including: the Amazon rainforests, California’s ‘tallest trees in the world’, mine sites in Australia and Peru, agricultural land in Dubai and trees growing on the permafrost in Northern Canada. ICT International now exports their precision instruments to more than 50 countries with their customers including environmental and forestry researchers and managers; mine site rehabilitation officers; agricultural, horticultural and glasshouse businesses; governments; scientific agencies; and universities throughout North and South America, Europe, the Middle East, India and Asia.

Through its commitment to innovative research, collaboration, and the manufacture and export of their precision monitoring instrumentation, ICT International is proud to provide world class scientific solutions enabling a greater understanding and improved management of water, soil, vegetation and the environment.

World’s best monitoring solutions focused on plant water use,
plant water potential and soil moisture management.

Scientific instrumentation developed for scientists by scientists.

The ICT International products are specifically designed to be deployed in rugged field environments, use low-power, have wireless and internet connection and firmware and software for detailed and sophisticated measurement and data processing in the field. In this regard they are totally ground-breaking, state of the art and unique.

There are no other products on the market today with the same functionality or application.

This unique family of digital sensors and data loggers grew out of an R&D innovation program which ICT International commenced in 2006. By committing a large percentage of its annual turnover to the innovation program which involved product research and design, cutting edge engineering design and active engagement and collaboration with the leading scientists in Australia and Internationally. ICT International has produced new scientific instrumentation needed by scientists to better understand how plants respond to the ever increasing problem of water shortage in our natural environment. The practical outcome being the accurate measurement of key plant and soil parameters for the advancement of plant and soils research to address plant physiology limitations to water availability, climate change, evaluation of plant genetics/breeding programs or fundamental understanding of plant function.

An environmentally sealed, low-power data logging platform forms the basis of ICT International’s technology for environmental monitoring and control applications.

A thorough and detailed understanding of plant response to water and the environment was developed from years working as a scientist and cotton consultant by Dr Peter Cull. Subsequent interaction with scientists around the world further developed this understanding.

This field experience and the appreciation of its scientific and commercial value have been transferred into instrumentation by engaging with the leading scientists in this field in Australia and internationally and experienced Australian engineers to develop the products.

The applications knowledge and experience of ICT International combined with scientific collaboration builds solutions that are recognised as world’s best and hence sought after by leading scientists worldwide.

What makes this unique product line innovative?

The innovation behind the family of ICT International products is the  underlying data logging platform, software and firmware protocols to interface an extensive sensor library both in terms of measurement parameter and output protocol. The wireless communications protocols to transmit data locally or internationally across any communications network. This technologically advanced data logging platform has been proven to function in environmental extremes using low-power.

The need to measure sensors within a range of both relative and absolute terms, depending upon the fundamental physical property of measurement, is paramount for high accuracy, repeatability and precision. In order to achieve satisfactory levels of resolution from µV to nanovolt resolution, solutions range from involving complex signal processing algorithms that can be included in onboard sensor microchips and require sophisticated output protocols to transmit the data to dedicated all in one logging solutions. The data logging solutions eliminate analogue signal noise caused by cable resistance and provide onboard signal conditioning and noise filtering to achieve the highly stable thermal noise conditions under which a measurement requiring nanovolt resolution can be resolved under ambient field conditions.

The ICT International data logging platform has been designed to accommodate all levels of sensor design, complexity and measurement principle by integrating all input variables from simple analogue millivolt inputs through to complex measurement principles requiring standalone, point of measurement data processing and logging instruments; that can seamlessly synthesise all of them into a single CSV file or MySQL database using a low power, unlicensed wireless protocol and GSM mobile telemetry solution.

The competitive innovative advantage of the encapsulated field experience, scientific knowledge and engineering detail has resulted in instruments which are sought by plant scientists worldwide. In fact, the continuous monitoring of plant water potential and leaf water potential, as measured by the PSY1 digital stem psychrometer has been sought by the plant science community for more than 40 years. The ability to measure low flow and reverse flow by the SFM1 digital sap flow meter is a world first and is enabling new discoveries of plant adaption to the environment.

Typical research topics include; hydraulic redistribution of water in trees in the Czech Republic, to measuring sap flow to determine water use of the different tree species in the Brazilian Atlantic Rainforest; to investigating tree recovery from drought in the USA.
