Hazards to work and rescue forces arise primarily because of the risk associated with asphyxiation on entering areas where oxygen levels have become depleted by displacement, combustion, oxidation or other chemical processes.
Since the late 1970s, electrochemical sensors based on consumable lead anodes have been the de facto standard for most applications, but, the aqueous electrolyte in these sensors can take up water from the air, or lose it to it, depending on temperature and humidity.
A particular problem with all lead-based sensors is the increase in the volume of the anode material, which occurs during oxidation. Lead oxide has a lower density hence a higher volume. This can cause higher pressure inside the sensor which can disturb functionality or force the electrolyte to leak due to a destroyed sensor housing.
GfG now offers a new series of lead-free smart sensors, offering a long operating life for a wider temperature and humidity range. Additionally, they meet the latest legal requirements regarding lead-free products and restrictions of hazardous substances.
Our smart O2 sensors are the perfect solution for even the most demanding environments. You can find out more about these sensors, and our range of portable gas detection.
