THE Safegard personal carbon dioxide monitor emits a piercing audible alarm, reinforced by a flashing red beacon, whenever it monitors dangerous concentrations of CO2 in the vicinity.
Since this gas is often stored in confined cellars and storage rooms, any leaks from pressure cylinders and other sources can quickly lead to high and potentially lethal gas concentrations.
The Safegard unit weighs 200g and clips onto a belt or can be hand-held. Its push-button controls enable fresh calibration to be completed in one step, with low-power dual wavelength infrared cell continuously monitoring gas levels, continually logging them at 30-second intervals. Price is £528 including battery charger.
