MicroCO Breath CO Monitor

With the MicroCO Breath CO Monitor, firefighters and emergency providers can diagnose carbon monoxide poisoning easily, quickly and inexpensively right on the scene thus preventing possible long term cardiac and/or neurological damage.

Studies have determined that breath carbon monoxide detectors such as the MicroCO can provides fast, inexpensive, and noninvasive estimates of the approximate concentration of blood COHb, facilitating diagnosis and treatment of CO poisoning. The MicroCO is the gold standard in CO breath testing and is the most advanced system currently available today. Some of its many features include fast response time, 1 ppm resolution, immediate display of CO levels in ppm and percent carboxyhemoglobin (%COHb) and color light indicators for a visual presentation of the results.

Measurements are easily obtained from a single exhalation and are aided by an auto-zero function at turn on, combined with a breath hold countdown timer. These results are then instantly display on the large, easy to read LCD and are visually represented by the appropriate color light indicator. Operating from a single 9 volt battery, the MicroCO combines accuracy and simplicity making it the preferred choice for all types of health professionals. The MicroCO is small, lightweight and is molded from high impact ABS plastic for durability.

In order to keep your carbon monoxide monitor in proper working condition and always have reproducible results at your disposal, Micro Direct recommends calibration every six months. Calibration can be easily and safely carried out by the end user.
