The SAN-0001 Personal CO2 Monitor protects you or your staff from dangerously high carbon dioxide levels indoors or in confined spaces. If high CO2 levels are detected, the monitor will alert the user to seek fresh air with a combination of flashing, audible and vibrating alarms. Low power consumption provides up to 48 hours continuous use and data logging on a single charge. Small enough to fit on a lapel or shirt pocket, the SAN-0001 CO2 Monitor uses non-dispersive infrared (NDIR) CO2 sensing technology to provide long life, accuracy and stability in daily use. Free data logging software is included.  For more information or to speak with our technical sales team please call 386-872-7665 or email us at sales@co2meter.com.
