COMMERCIAL CO MONITOR

ProTech 8505 Battery Powered Commercial CO Monitor w/Digital Display and Memory

    Model 8505

  • Battery Powered
  • Digital LCD Readout
  • Display Backlight
  • Peak Level Memory
  • Peak Level Time Record
  • Electrochemical Sensor
  • Sensor Life Monitor
  • ACGIH, Cal/OSHA, NIOSH and OSHA Compliant
  • One Year Warranty

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. Backed by a one year limited factory warranty.

Alternate CO monitor for commercial applications: Defender LL6070

FEATURES

  • Battery Powered: The ProTech 8505 Commercial CO Monitor includes a 9v alkaline battery.
  • Continuous Digital Display: CO levels detected between 10 to 999 ppm are continuously displayed in the alpha-numeric readout.
  • Peak Level Memory: Recalls from memory the highest CO level detected within last 30 days from 10 to 999 ppm.
  • Peak Level Time Record: The duration of the stored peak CO level, and how long ago it occurred, can be displayed by pressing the memory recall button.
  • Electrochemical Sensor: The electrochemical sensor is exceptionally reliable and accurate.
  • Sensor Life Monitor: Internal clock starts once battery is installed. Visual and audible signals notify you when sensor life has expired.
  • ACGIH, Cal/OSHA, NIOSH and OSHA Compliant: The ProTech 8505 complies with ACGIH, Cal/OSHA, NIOSH and OSHA workplace exposure limits.
  • One Year Warranty: The Pro-Tech 8505 Commercial CO Monitor is backed by a One Year Limited Factory Warranty.
