Established in 1971, Cambridge based Delta-T Devices is a high-tech co-operative which designs instruments for measuring and monitoring the environment. They have a strong focus on soil moisture, precision irrigation, agronomy, plant physiology, eco-physiology, data logging, solar radiation and meteorology.
Their soil moisture kits provide cost effective and accurate soil water measurements; the kits are portable and can take hundreds of readings per hour. The PR2 Profile Probe can accurately measure vertical profiles of soil moisture to a depth of one metre, while their innovative WET Sensor provides soil salinity and moisture measurements, allowing nutrient level monitoring and fertigation control.
Combining soil and environmental sensors with powerful Delta-T Data Loggers can form custom weather stations for accurate weather monitoring. The 12 channel GP2 Data Logger and Controller is weatherproof, rugged, and offers advanced control capabilities, with water savings of 60% possible when used for precision irrigation.
Delta-T’s plant science products include the SunScan system, which quantifies solar radiation penetration into low uniform canopies and displays Leaf Area Index – a measure of crop performance. The AP4 Porometer measures the rate of water diffusion though leaf surfaces and displays stomatal conductance – an indicator of water stress.
