  Commercial Carbon Monoxide Monitor - For the Workplace  
             
 

Pro-Tech Commercial CO Monitor

 

 

  The PRO-TECH 8505 Battery Powered Commercial Carbon Monoxide Monitor includes a continuous digital display, peak level memory, TWA readout, sensor life monitor, and smart backlight.

Carbon monoxide (CO) levels are sampled and recorded every second by an accurate and reliable electrochemical sensor. CO levels detected from 10 to 999 ppm are automatically displayed in the LCD readout. When a chronic carbon monoxide level of 20 ppm or more is detected, a flashing Red LED and 85db pulsating alarm are activated.

Pressing the reset button temporarily mutes the audible signal while the carbon monoxide level is rechecked. If the monitor continues to detect carbon monoxide levels of 20 ppm or more, the audible and visual alarm signals will reactivate automatically within 5 minutes. If carbon monoxide levels drop below 20 ppm, the alarm signals will not be reactivated.

The highest carbon monoxide level detected from 10 to 999 ppm, the duration of the peak level, how long ago the peak occurred, and the average CO level detected for the previous 8 hours can be displayed by pressing the memory button. An internal clock monitors the sensor life and activates visual and audible sensor expiration signals after two years.

The Pro-Tech 8505 Commercial Carbon Monoxide Monitor complies with ACGIH, Cal/OSHA, NIOSH and OSHA workplace exposure limits.
