Super Lightweight Personal CO2 Alarm

Specifically designed for employees who work in enclosed areas, or those who visit different sites, where carbon dioxide buildup can cause serious harm to health.

The extremely lightweight personal safety alarm clips to a shirt pocket, lanyard, or belt without drag. Designed to alert the user and people in the area to dangerous carbon dioxide leaks, the CO2BUDDY features high visibility LED’s, a loud alarm and powerful vibration motor. 

“The new smaller CO2Buddy is really good to wear either on a lanyard or belt. It performs well and is accurate. The lack of the complicated calibration with gas bottles etc is a huge improvement” Darren from Palmers Brewery

Available worldwide, the CO2BUDDY has multiple pre-configured alarm set-points to comply with the most common safety regulations and jurisdictional requirements, which can be different by country, region, state and municipality. 

The CO2BUDDY pre-configured alarm set points meet safety standards across the globe including Europe’s EH40 legislation, OSHA and NIOSH TWA requirements in the United States.

Very simple to operate, the user can select pre-configured alarm set points which all feature a TWA (Time Weighted Average) alarm, continuously monitoring the environment over an 8-hour period. 

CO2BUDDY can be easily charged by a supplied micro USB cable, with a battery life of a minimum of 12 hours on a single charge.

Suitable for gas delivery drivers, or those who visit different sites across multiple locations across the beverage and hospitality industry including pubs, bars, restaurants, stadiums, shopping malls and breweries, and laboratories, medical facilities or those involved in cryogenic process monitoring. 

From initial power-up, you must allow a two-hour charge and perform a quick fresh air calibration. Your CO2BUDDY is then ready to protect you!
