The new Retrotec 450 series are small yet high-power positive and negative duct leakage testers that can evaluate systems to pressures beyond 5kPa.
Available from BSRIA Instrument Solutions, the units are available in 110V and 230V version as well as a Wi-Fi gauge option.
These innovative instruments reduce testing time using precision flow orifice plates that can be changed in seconds. Portable and lightweight, they incorporate a fan weighing just 9.5kg.
Results are displayed in any flow units corrected to STP, and the DM32 digital touch screen pressure gauge has an accuracy of +/- 0.5% of a reading.
