Temperature Humidity Oxygen Analyzer KGD-YQ-518 For Standard DN65 Flange Installation And Standard Length 800mm Probe
In - situ High - temperature Humidity & Oxygen Analyzer KGD - YQ - 518 is used in high - temperature environments.
Product Introduction
The In - situ High - temperature Humidity & Oxygen Analyzer KGD - YQ - 518 incorporates the internationally advanced solid - state electrolytic ceramic sensing technology for dry and wet oxygen measurement. It adopts the limiting current method for humidity measurement and can stably monitor flue gas humidity in high - temperature and highly corrosive environments for a long time. The core sensor of this instrument is designed with a high - temperature - resistant structure, with a maximum temperature resistance of up to 500°C, enabling it to operate stably in high - temperature environments for an extended period. In addition to its high - temperature - resistant performance, this product also has advantages such as high measurement accuracy, strong corrosion resistance, and fast response speed. In harsh working conditions such as those rich in heavy metals, highly corrosive, highly humid, and with complex organic matter interference in volatile organic compounds (VOCs), this instrument can continuously measure humidity and oxygen content online with stable and reliable performance, meeting the requirements of HJ 75 - 2017 and HJ 76 - 2017 standards for online monitoring technology of flue gas humidity and oxygen.
Product Features
- Adopts the third - generation solid - state electrolytic ceramic sensing technology for dry and wet oxygen measurement, with more stable performance.
