CO / CO2 measurement in the heated environment
Carbon monoxide (CO) is a colourless, odourless and taste-free gas, but also poisonous. It is produced during the incomplete combustion of substances containing carbon (oil, gas, and solid fuels, etc.). If CO manages to get into the bloodstream through the lungs, it combines with haemoglobin thus preventing oxygen from being transported in the blood; this in turn will result in death through suffocation. This is why it is necessary to regularly check CO emissions at the combustion points of heating systems and in the surrounding areas.
Measuring humidity
Humidity is an important parameter for health and comfort. Above all, relative humidity is the significant factor - it indicates the extent to which air is saturated with water vapour.
With relative humidity of 50%, the air contains just half the maximum amount of water vapour that it could at the right temperature. At 100% relative humidity, the air is completely saturated with water vapour. If 100% saturation is exceeded, the excess moisture condenses into condensate.
Therefore, relative humidity can indicate how fast evaporation will take place or the likelihood of condensation forming. As the evaporation of moisture through skin is determined by the relative humidity of the ambient air, the latter is an important parameter for the feeling of comfort.

Gas leak detector for new users – testo 317-2
Leaky gas pipes not only lead to higher gas consumption, but can also trigger explosions and fires in the worst case scenario. Because leaks are often difficult to detect with the naked eye (for example with smallest hairline cracks), gas measuring technology is useful when it comes to testing gas pipes.
