non-contact moisture meter

The Production-Grade Standard for Online NIR Moisture Analysis

The KJT703 measures moisture and water activity continuously to 0.001% on open production lines: belt conveyors, screw conveyors, sluices, drop chutes, and gravity feeds. The sensor sees the product directly, scans at 0.1-second refresh, and reports moisture in real time. It shares the field-proven online platform of the KJT700 composition analyzer, configured for moisture measurement alone.

Solving Production Moisture Challenges

• Spot checks miss most of your product: Pulling samples once per shift means most of production runs without measurement. The KJT703 delivers continuous moisture analysis at 0.1-second refresh, so every meter of product is verified, not just the sample on the lab bench.
• Lab turnaround is too slow for process control: Oven-drying a moisture sample takes minutes to hours. By the time the result arrives, the line has already produced material against the wrong setpoint. The KJT703 closes the loop in real time, feeding live moisture data to your control system.
• Contact methods disturb the product: Probes and manual sampling interrupt the line and can mar finished or delicate surfaces. Non-contact NIR reflectance reads moisture from 350 mm above the product, touching nothing.
• Harsh process environments destroy lesser instruments: NEMA 12 housing protects against dust and water. The integrated air purge snout keeps the optical window clean in heavy-dust applications. Explosion-proof and CIP configurations are available for hazardous and food-grade installations.

Built for Production

The KJT703 measures across an approximately 50 mm spot at 350 mm focal length, scanning continuously at 0.1-second refresh. Up to 99 moisture calibrations are stored on each sensor head, and multiple heads network to a single connection for multi-point installations across a production line. NIR reflectance keeps the measurement non-contact and non-destructive, with automatic zero adjustment and on-board self-diagnostics for unattended operation. Each KJT703 ships with Kett's One-Year Total Care Warranty on parts, labor, and specification compliance. Post-warranty maintenance agreements and on-site calibration services are available. Need composition, not moisture alone? The KJT700 Online NIR Composition Meter measures up to nine organic components on the same open-line platform, adding protein, fat, oil, sugar, and more alongside moisture. Need moisture in a smaller, PC-free footprint? The KB30 Online NIR Moisture Meter is the world's smallest inline NIR sensor, a moisture-only smart sensor that needs no PC, for single-point installations where the full platform is more than the job requires.
