Application of a New type of nitrogen dioxide sensor in high humidity We are pleased to announce the release of the GS + 4NO2-HH, a new addition to our industrial sensor product line and one of our upcoming product lines designed for high humidity applications such as mining. In high relative humidity (RH) application scenarios, traditional electrochemical sensors may not work properly due to excessive humidity, resulting in performance degradation and high downtime costs. The GS + 4NO2-HH is designed to meet these challenges, and its application-specific configuration ensures reliable nitrogen dioxide monitoring, even in demanding conditions. Nitrogen dioxide (NO2) is a hazardous pollutant associated with serious respiratory health risks, environmental damage, and intense regulatory scrutiny. Accurate detection is critical, especially in harsh, high-humidity, or confined environments where standard sensors often fail. Performance Improvement of Ammonia SensorLong-term testing of our iterative ammonia sensor has shown that the long-term output drift has been reduced from 20% PA to less than 10%. This improvement is the result of ammonia sensor design and production enhancements affecting the following sensors: GS+4NH3 - 100 GS+4NH3 - 300 GS+4NH3 - 1000 GS+7NH3 - 100 GS+7NH3 - 1000The data sheets for these products have been updated to reflect this change. Notification of Change in Sensor Housing Molding Please note that due to the new changes in the DDS line, some sensors will soon have a black housing instead of the previous red or blue appearance. This change affects the following products: ·GS+4CL2 ·GS+4SO2 ·GS+4NO ·GS+4NO2-E ·GS+4CO F-M ·GS+4NO-E ·GS+4SO2-E ·GS+4ETOThe purpose of these changes, which will take effect shortly, is to ensure that our sensors continue to deliver the value proposition of the manufacturer. By consolidating the sensor body into a single color, we improve our volume purchasing capabilities and help maintain our cost advantage. In the future, more shells will have black bodies, and we will inform you of this change in advance through a technical bulletin.
