The PRO-TECH 8505 Battery Powered Commercial CO Monitor includes an electrochemical sensor, continuous
digital display, peak level memory, duration and time of peak level, TWA
readout, sensor life monitor, and manual backlight.
CO levels are sampled and recorded every 5 seconds by a state-of-the-art electrochemical sensor, and continuously displayed in the LCD readout. When a chronic
CO level of
30ppm 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
CO level is rechecked. If the monitor continues to detect CO levels
of 20 ppm or more, the audible and visual alarm signals will reactivate automatically within 5 minutes. If
CO levels drop below 20 ppm, the alarm signals will not be reactivated.
The highest CO level detected (from 10 to
500 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 expiration signals after two years.
The Pro-Tech 8505
Commercial CO Monitor complies with OSHA and NIOSH exposure
limits. Backed by a one year limited factory warranty.
