How long does a VOC sensor last? VOC sensors based on Photo-Ionisation technology (PID) are more complex than most other types of gas detector. PID based detectors utilise an Ultra-violet (UV) lamp to ionise the gas sample. The life of the UV lamp is one of the on-going costs of ownership for this type of detector. This article delves into the typical lamp life currently on the market and why it is capped at a certain amount. IGDs specialist knowledge in PID detection however allows us to set the standard with our revolutionary new development in VOC sensor technology.
