NIST Traceable
Precision moisture analyzer sensors engineered for high-temperature industrial environments. Our patented solid-state technology delivers accurate humidity measurements up to 1200°F without chemicals, wet bulbs, or compressed air. Ideal for stacks, ducts, furnaces, kilns, and process monitoring in metal processing, cement manufacturing, power generation, and food processing applications.


These moisture analyzers use patented solid-state technology to measure humidity in industrial processes at temperatures from 40°F to 1200°F (with optional capability to 2400°F). Unlike traditional methods, the process eliminates the need for chemicals, compressed air, wet bulbs, or optical components, providing ±1% of %MBV full scale accuracy with fast 60-second response times for continuous monitoring in stacks, ducts, furnaces, and kilns.
