This personal CO₂ safety device is portable, super lightweight and has been specifically designed for employees who work in enclosed areas, or those who visit various sites, where carbon dioxide (CO₂) buildup can cause serious harm to health.

Unlike most portable CO2 monitors which require you to send the device back to the manufacturer for calibration, the CO2BUDDY allows you to calibrate on site, all you need is fresh air! Saving you time and money, the CO2BUDDY is perfect for those who like to get the job done.

Your 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!

How it works

Designed to alert the user and people in the area to dangerous carbon dioxide (CO₂) leaks, the CO₂BUDDY features high visibility LED’s, a loud alarm and powerful vibration motor.

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.

What can it prevent?

The CO₂BUDDY can keep you safe from dangerous levels of carbon dioxide (CO₂) by instantly alerting you when the levels reach a certain limit (user-specified).

Up to date with Regulations

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.

Let us take care of you, so you can take care of them.

Saving lives and rapid crisis response is at the heart of what we do. We design our systems in a way that enables you to focus on the job at hand, delivering the best possible care for your patients.

"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

With pressures on supermarkets and warehousing at an all time high, it's now more important than ever to ensure that carbon dioxide (CO₂) delivery or delivery of refrigerated food can reach its destination on time, securing the essential supply chain for the nation. 

Carbon dioxide (CO₂), or R744 as it's known in the refrigeration industry, can be extremely harmful if levels breach 1.5%. EH40 and OSHA regulations state you cannot be exposed to 1.5% of carbon dioxide (CO₂) for more than just 15 minutes. 

We are the experts in carbon dioxide (CO₂) detection and have almost 40 years of keeping people safe under our belt. With the CO₂BUDDY on your belt, you can rest assured that you are safe while you perform the critical work of providing essential goods.
