Toxic gases do not have much cross-sensitive effect on the DDS oxygen sensor S+4OX3 at the allowable concentration, and highly oxidizing gases (such as percent-level ozone, chlorine) will interfere with the diffusion of oxygen at high concentrations, but most ordinary gases do not.

Important note: Acidic gases such as carbon dioxide, sulfur dioxide will be absorbed by the electrolyte, increasing the flow of oxygen to the electrode, so that each 1% of carbon dioxide will increase the oxygen signal by about 0.3%, therefore, the DDS oxygen sensor S+4OX3 is not suitable for continuous operation at carbon dioxide concentrations greater than 25%.

The Oxygen sensor S+4OXLF is a three-electrode lead-free oxygen sensor suitable for industrial safety and emissions.

The oxygen sensor S+4OXLF is a very high-performance, long-life oxygen sensor with good repeatability, which solves the poor performance of the ordinary Garvalnik principle oxygen sensor and is RoHS compliant. The oxygen sensor has a measuring range of 0-30%O 2 and a temperature range of -40 ° C to +60 ° C.

The working principle of the oxygen sensor S+4OXL is the fuel cell principle, which is different from the traditional lead-based oxygen sensor based on the Gavarnik principle, which does not affect the life of the anode consumption. The S+4OXLF oxygen sensor is designed to last more than 5 years and is standard in the Industry 4 Series package.
