The Lysimeter is a fully automatic weighing system designed for monitoring weight changes in plant growth systems allowing researchers to assess information such as evapotranspiration and soil nutrient uptakes.
Accurate results
The heart of the weighing system is a series of loadcell sensors which can be connected together to take a continuous series of measurements over a given time period which is programmed by the researcher . Readings can be taken from every second to readings every matter of days.
The effect of changing influences such as temperature or humidity can be monitored by reporting the weight changes to our bespoke software.

Griffith Elder weight lysimeters were designed in 2003 for an experiment to study the physiology related to the water use of 5 hybrids of willow coppice. The weights of the lysimeters were close to 400 kg and were measured continuously and logged every 20 minutes.

"The Data-maid software was very handy to programme the logging intervals of the load cells and to store a large amount of data. The data was logged as mass in kg with a precision of 0.02kg . The information collected allowed us to quantify precisely the water consumed by the plants and to visualise the evolution of water consumption rate as water stress evolves.
Finally new fields of study are open as a new generation of weighing lysimeter emerged through the development of efficient and reliable load cells and software by Griffith Elder".
