About This Product

The QMA601 Quartz Crystal Moisture Analyzer uses a next generation advanced quartz crystal to provide reliable, fast and accurate measurement of trace moisture content in applications where minimizing moisture in the process is critical. is designed to provide. This product provides consistent and accurate measurements of trace moisture in sampling lines. This "consistency" is achieved using a self-calibration system that calibrates the sensor relative to an internal moisture generator. The moisture generator remains traceable to NPL and NIST, ensuring long-term stability of measurements. QMA601 has obtained domestic explosion-proof certification. In April 2018, this product was approved by "CSA UK", which is certified as a designated foreign certification body by the Ministry of Health, Labor and Welfare, as a "pressure-resistant explosion-proof structure" and "dust explosion-proof container. Passed the type test for "Structure". Suitable for use with natural gas containing up to 20% hydrogen.

■Features

・Obtained domestic explosion-proof certification ・Measurement range: 0.1~2,000ppmv ・Accuracy: 0.1ppmV or 10% (reading value), whichever is greater ・Longer maintenance cycle (3 years)

■Application

・Glycol dehydration of natural gas ・Monitoring of dehydration/drying status using molecular sieves ・Transportation and storage of natural gas ・Improving refinery quality – Monitoring recycled gas ・Production of ethylene and propylene ・LNG production/revaporization ・Recycled hydrogen from oil refinery plants
