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.
Online NIR Moisture Sensor: Smart Head Design, Runs With or Without a PC
The measurement head at the center of Kett's production line moisture systems. All calibration and calculation happens inside the head, so it reads on its own LED at the line and reports to a control system without a PC in the loop.
99 Calibrations in the Head: Store a curve for every product you run and switch channels without touching the software.
Reads at the Line: A bright LED on the head shows moisture, absorbance, and channel, so production staff never walk to the control room for a number.
Compensated for the Plant Floor: Temperature and humidity compensation, with the humidity sensor built into the air purge hood.
Built to Stay Out There: Aluminum casting, dust proof and drip proof, mounted above the line on four bolts.
High Moisture Online NIR Sensor: Smart Head Design for Wet Product
The special order high moisture configuration of the KJT330 sensor. Same self contained head mounted above the line, set up with the high moisture zero standard for product running wet.
Built for Wet Product: Configured at the factory for high moisture applications, including slurries, pastes, and washed material.
99 Calibrations in the Head: Store a curve for every product you run and switch channels without touching the software.
Reads at the Line: A bright LED on the head shows moisture, absorbance, and channel at the point of measurement.
Compensated for the Plant Floor: Temperature and humidity compensation, with the humidity sensor built into the air purge hood.
