When Turnkey Instruments’ customers need air quality and noise pollution measurement at a remote site, Turnkey uses the Leading Edge LE-300 wind turbine along with solar to power their equipment.

Often construction sites and quarries have no mains power nearby – even if they do, an intermittent supply means a reliable off-grid power solution is needed. The LE-300 wind turbine is renowned for its reliability and robustness, ensuring it continues producing power even during storm force winds.

Turnkey’s Osiris air pollution monitors and their iVIBE noise and vibration monitors are deployed where there’s large-scale earth moving, and along major construction projects such as the high-speed railway line HS2. Other typical applications include roadside monitoring and at oil and gas plants.

Together Osiris and iVIBE consume 22W, a load addressed with 1 x LE-300 wind turbine and 2 x 130W solar panels with the power stored in 12V leisure batteries. This equipment is mounted on a metal-frame quadpod along with the instruments themselves and the Turnkey power/comms unit, the Power Portal.

The Power Portal’s SIM gives remote access through Turnkey’s AirQWeb platform, collecting data, generating alerts and reports, and allowing user control of the instruments.

Turnkey’s customers are generally either the companies working at the site, environmental monitoring companies, or environment agencies and local councils that have responsibility for monitoring air quality, noise and vibration.

Commenting on the LE-300 wind turbine, Dr Nick Barton, Development Scientist at Turnkey said “We have been happy with the performance and reliability of the LE-300 wind turbines over the last four years, and based on this experience we will continue to deploy them as reliability is critical, especially as monitoring pollution is often a legal requirement for our customers.”
