The Castle Trade In programme will accept any sound meter – regardless of make or age – and use it as payment towards a new dBAir.

Simon Bull, MD of Castle Group, said: “Our dBAir Sound Meters are proving to be a popular choice with busy professionals, who are making the most of the time saving WiFi Data Transfer which is built into all dBAir models. Adopting the dBAir’s simplicity and forward thinking Cloud Software is a smart investment,
especially now with our limited time Trade In offer.”
