The Carbon Monoxide Meter CO9917C detects the presence of carbon monoxide (CO) in the air with great accuracy. The meter is equipped with the most up to date technology and its detector will guarantee the accuracy of measurements from 0 to 999 parts per million (PPM). The meter indicates the presence of carbon monoxide in three ways by a reading on the LCD in PPM with a beeper tone and LED alarm. Three different tones correspond to 100%, 200%, 300% emergency levels or 50, 100, 150 ppm:

• From 0 to 50 ppm - no sound alarm
• From 50 to 100 ppm - a 'beep' every two seconds
• From 100 to 150 ppm - a double 'beep' every second
• Over 150 ppm - a 'beep' every half second

FEATURES

• Digital LCD display
• SnO2 semi-conductor technology
• Detection range 0-999PPM
• Visual and audible alarm
• Automatic test each time detector is switched on
• No recalibration needed for several years
• Max Hold function
• Low battery indication
• Display of ambient temperature
• Pocket size and easy to use
• Connector for recharging system
