General Description

The Carbon Monoxide Meter is designed with a high accuracy CO sensor, providing high accuracy, fast response and stable readings. It is used to detect the presence of carbon monoxide in wide applications:

• Poorly maintained furnaces, gas heaters, or fireplaces.

• Dirty or plugged chimneys, or flue exhausts.

• Poorly maintained gas, oil, or kerosene appliances.

• Internal combustion engines (e.g., automobiles, lawnmowers, blowers).
  The Meter indicates the presence of CO by a reading on the LCD and a beeper tone. The beeper functions much like clicking of a Geiger counter:

• Above 200 PPM, the beeper sounds continuously with the concentration of CO.

• From 35 PPM to 200 PPM, the beeper sounds discontinuously with the concentration of CO.

Features

• Sensor: Stabilized electro-chemical Gas-specific
• Measurement range: 0 ~ 1000 PPM
• High accuracy
• Large LCD display
• Accuracy is not affected by humidity
• Sensor drift is small so that the measurement reading is stable
• Compact, light, and easy to carry
• Low battery consumption, long battery life
