Product Overview

The Crowcon Cellarsafe is designed for use in breweries, laboratories and cellars, with the ability to detect carbon dioxide and / or oxygen. Reacting to the manufacturers pre-set levels, the Cellarsafe unit will pre-alarm if the unit detects the lower threshold of either gas (1.5% for CO2 and 19.5% for O2) and will fully alarm should the gas level reach the higher threshold (3% for CO2 and 18% for O2).

When monitoring the amount of oxygen in the unit's environment, the Cellarsafe is designed to warn persons that levels of oxygen have fallen to dangerous levels in terms of breathing, and reacting similarly if CO2 rises to potentially dangerous high levels.
