Carbon monoxide (CO) levels are measured and recorded by a state-of-the-art electrochemical sensor. When a chronic carbon monoxide level of 40-70 ppm or more is detected, a flashing Red LED and 85db pulsating alarm are activated, and the carbon monoxide level is alpha-numerically displayed up to 500 ppm.

Pressing the reset button temporarily mutes the audible signal while the carbon monoxide level is rechecked. If carbon monoxide remains at 40-70 ppm or higher, the visual and audible alarm signals are automatically reactivated. After ventilation, the LED is auto-reset to a flashing Green (power on), the audible signal is silenced, and detection restarts.

The highest carbon monoxide level detected (peak), from 10 to 500 ppm, and time duration for peak level can be recalled from memory by pressing the test/reset button.  Current carbon monoxide levels and COHb calculations can also be displayed.

An internal clock monitors the sensor life and activates visual and audible expiration signals at five years.  The Lithium battery included should last the life of the carbon monoxide detector.

• Lithium Battery Powered:  A five year UltraLife 9vDC lithium battery is included with each Pro-Tech 7035 carbon monoxide detector.
• Electrochemical Sensor:  This state-of-the-art electrochemical sensor is exceptionally reliable and accurate, with an estimated 5 year life expectancy.
• Digital Display:  Carbon monoxide levels detected between 40 to 500 ppm are automatically displayed when alarm is activated. The LCD readout flashes above 500ppm.
• Current CO Display:  The current carbon monoxide level detected can be displayed from 10 to 500 ppm.
• Peak Level Memory and Time Record:  The highest carbon monoxide level detected from 10 to 500ppm, and the duration of the peak level, can be recalled from memory by pressing the test/reset button.
• Sensor Life Monitor:  An internal clock is activated once the lithium battery is installed.  Visual and audible signals notify you when the sensor life has expired.
• UL 2034-02 Listed:  Pro-Tech carbon monoxide detectors are Underwriters Laboratories (UL) tested and listed to the latest standard ANSI/UL 2034-02.
• CSA & IAS Certified:  The model 7035 is certified to CSA 6.19-01 and IAS 6-96-2nd Edition, carries the Blue Star and Blue Flame approvals, and includes CSA's Lifetime Reliability Testing.

• Complies with NFPA 720-05:  Meets the National Fire Protection Association's Recommended Practice for the Installation of Household Carbon Monoxide (CO) Warning Equipment.

• ISO 9001 Quality Management System:  An internationally recognized, rigorous framework for enhancing product quality, reliability, and customer confidence.

• Five Year Warranty:  The Pro-Tech 7035 lithium battery powered carbon monoxide detector is backed by a five year limited factory warranty.
