Four Component Online Analysis: Moisture Plus Three More, Continuously
Continuous measurement of four components on a running line without sampling, contact, or product loss. Moisture plus three organic constituents, measured together and delivered to your control system as the product moves.

Product specification rarely comes down to one number. The KJT500 measured four components at once on a running line, using near-infrared reflectance so nothing was sampled, contacted, or lost to testing. Moisture plus three constituents, from a single head over the line.
The head measures from 350 mm above the surface across a 50 mm spot and responds in approximately two seconds. It stores 99 analytical curves fitted from your own reference values, and drives control loops directly through analog output. The aluminum casting is dust proof and drip proof, the air purge hood keeps the optical window clear, and the tungsten lamp and filter motor are both rated at 20,000 hours. Kett Tracker on the connected PC provides a relational database with real time graphing, and additional heads could be added up to four per processor board.
Each system shipped with Kett’s One Year Total Care Warranty covering parts, labor, and specification compliance. Maintenance Agreements are available.
The KJT500 is no longer manufactured. The sensor head was also sold on its own as the KJT500SH.
Need multi component analysis on your process line today? The KJT700 Instant Online Composition Meter is the current online composition platform, measuring moisture alongside additional organic constituents in a supported system.
