Delta-T Devices provides a wide range of research-grade sensors for meteorological, hydrological, and environmental measurement and monitoring.
Our plant science measurement instruments include:
AP4 Porometer
The AP4 Porometer measures the stomatal conductance of plant leaves quickly and easily. It is a highly practical instrument for field work, being based on the cycling diffusion principle, which makes it possible to have a lightweight sensor head (130g) and to run quick calibration checks in the field.
WinDIAS Leaf Image Analysis System
WinDIAS provides high speed measurement and analysis of leaf area and leaf features. It enables accurate measurement of total leaf area and percentage diseased/healthy leaf area, as well as perimeter, length, width and object count.
Three systems are available; Entry Level – with flatbed scanner, Standard Level – with video camera, lightbox, and overhead lighting, and Rapid System which adds a conveyor belt unit for high-speed throughput of leaves (up to 800 an hour).
SS1 SunScan Canopy Analysis System
The SunScan canopy analyser is optimised for use in low canopies – including many types of agricultural crops. It permits rapid spatial averaging of large areas, and PAR mapping for non-uniform crops. The SunScan is usable in most weather conditions.
