Measurement technologies developed by the UK’s prestigious National Physical Laboratory (NPL) played an important part in the development of Delta-T Device’s latest digital multi parameter sensor – the WET150. A key aim of the development project was to create a research grade sensor at a price point that encourages increased…
Delta-T Devices has created a new 3 minute animated video, providing a comprehensive and visually engaging overview of the PR2 Profile Probe. It explains how the PR2 works, how it is installed - and how it can be used to obtain accurate measurement of soil water content at defined depths…
Delta-T Devices is proud to have achieved ISO 9001 certification. Awarded to Delta-T Devices in August 2011, ISO 9001 is an international standard in use worldwide as a benchmark for quality. The award follows a thorough assessment of our quality management systems by the highly respected British Standards Institution (BSI). Delta-T Devices has…
Delta-T Devices is pleased to announce the arrival of the SM150 Soil Moisture Sensor which can be used with the new HH150 Reader to create a very cost effective method for monitoring irrigation efficiency. The SM150 Sensor has been designed for repeated insertion into soils and substrates, the sharp pins causing minimal disturbance; while the…
Marine AOD measurements matter because aerosols can affect respiratory health, climate change, and the safety of aircraft during volcanic events. However, routine marine Aerosol Optical Depth (AOD) surface-based observations are in short supply because it is both difficult and expensive to operate conventional automatic sun photometers at sea. Two prototype…
The improved Delta-T Devices BF5 Sunshine Sensor is a versatile, multi-purpose solar radiation sensor. It uses an array of photodiodes with a unique shading pattern to measure incident solar radiation from which it calculates the global and diffuse components of the radiation. It also measures sunshine duration. Improved Design The…
Delta-T Devices has launched a new digital version of their well-established analogue PR2 Profile Probe. Named the PR2 SDI-12, it shares the many strengths of the analogue version (which remains in production), but with the addition of SDI-12 compatibility - allowing integration into new and existing SDI-12 systems. As with the…
Delta-T Devices's Dr John Newstead gives a comprehensive overview of the PR2 Profile Probe in our new video. He demonstrates how to install the PR2, explains how the probe can be used for both portable readings and installed long-term monitoring, and shows how accurate soil profile moisture measurements (down to…
