Carbon dioxide (CO2) is a tasteless, odourless gas that can pose potential risks for humans who may not even be aware they have been exposed. Government agencies now mandate CO2 monitoring in most work environments worldwide. In order to comply with EH40 legislation in Europe and OSHA standards in the United States, facilities typically install fixed units that can monitor large enclosed spaces, protecting employees from potential build-ups or leaks.

While the Analox Group offers a complete range of customizable fixed location units that very effectively satisfy local codes and regulations, one place where these types of monitors are less effective is in the area of personal monitoring and safety in confined spaces. This is where the Analox CO2BUDDY excels.

The CO2BUDDY is ideal for workers who operate in multiple locations or who move products from one area to another throughout the day. The different areas and locations could produce exposure to various levels of CO2. Workers entering these different environments can be susceptible to CO2 exposure without even knowing it.

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.

While brief exposure to CO2 is common throughout the workday, it’s the potential build-up of the gas from different locations that can often put employees at risk. The CO2BUDDY monitors the average CO2 level over an 8 hour period and will alarm when the overall exposure becomes harmful.

Lightweight, portable and highly effective, the CO2BUDDY is one of the smallest and lightest personal CO2 monitors available today. Designed with user comfort and convenience in mind, the unit can be clipped to a shirt pocket, belt or lanyard with little interference with the monitoring process.

The CO2BUDDY uses state of the art Non-Dispersive Infrared (NDIR) technology to detect CO2. The NDIR system monitors the air in the surrounding environment for the specific CO2 elements. No additional “control” or “calibration” gasses are needed. The simple to operate unit protects users and those nearby by alerting them to CO2 leaks or buildup with multiple alarms – a high visibility LED display, a loud and powerful audible alert and a powerful vibration motor. The vibration setting is ideal for workers in noisy environments where the audible alarms could be drowned out by background noise. Users can customize which alarm setting they prefer.

The CO2BUDDY is currently in use worldwide in such diverse industries as food and beverage, hospitality, research laboratories, medical facilities with cryogenic process monitoring, food processing and storage facilities and stadiums. Gas delivery drivers who service many of these industries on a daily basis are key target users of the CO2BUDDY.

The CO2BUDDY has multiple set-points to comply with the most common safety regulations and jurisdictional requirements, which can be different by country, region, state and municipality. The unit comes with pre-configured alarm set points that 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 the pre-configured alarm set points which all feature a TWA (Time Weighted Average) alarm, continuously monitoring the environment over an 8-hour period.

The environmentally-friendly CO2BUDDY features a rechargeable battery that can easily last a minimum of 48 hours on a single charge. The unit is designed to be charged overnight or during off-hours, virtually eliminating the need for service returns or battery replacements.

This advanced monitor is also extremely durable, offering long-lasting sensor life and reliable personal monitoring for virtually anyone who may come into contact with CO2 during the course of their day.

The CO2BUDDY has been providing an added level of safety and security worldwide since its introduction in 2019. This impressive REVIEW OF CO2BUDDY BY provides a fresh perspective of the product’s benefits and specific applications.

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!
