SafeCellar™ – KDF

Cost effective Carbon Dioxide (CO2) and Oxygen (O2) monitor for breweries, wineries, cellars, beverage dispensing areas, fast food outlets, hospitals, universities and industrial laboratories.

From fermentation through to distribution, CO2 is one of the most common hazards to health in breweries, cellars and drinks outlets. It is also the fourth most abundant gas in the atmosphere. Long term exposure to only 0.5% volume represents a toxic health hazard. Concentrations greater than 15% volume can lead to death.

SafeCellar ™ has been designed specifically to warn personnel of these hazards.
