Product Overview
Smart cartridge designed by Kunak that integrates a sensor capable of accurately and reliably measuring Carbon monoxide levels.

• GasPlug TECHNOLOGY | PATENTED DESIGN

Where is it found?
CO is found in fumes produced any time fuel burns in cars or trucks, small engines, stoves, lanterns, grills, fireplaces, gas ranges, or furnaces. Improperly ventilated appliances and engines, particularly in a tightly sealed or enclosed space, may allow carbon monoxide to accumulate until dangerous levels.
Why is it harmful?
Carbon monoxide or CO is an odourless and colorless pollutant gas that can cause death. When CO is inhaled into the body, it mixes with the blood avoiding the oxygen absorption. The CO exposure of a person over a certain period of time can cause illness and even death.
CO Cartridge
The carbon monoxide cartridge has a built-in electrochemical sensor with very low noise electronics allowing the measurement from very low concentrations (ppb) up to several ppm. There are two measurement ranges to cover different applications:

• Type A measuring most common concentrations range to 12,000 ppb.
• Type B, a higher range version that can measure up to 500 ppm, with reduced accuracy at low concentrations.

This cartridge is very stable over time and, in non-extreme environments, can last several months longer than specified.
