Portable NIR Composition Analyzer: Multi-Component Analysis You Carry to the Sample
A battery-powered handheld that reads several organic components at once from a single non-contact measurement. Point it at a surface from about 150 mm, and near-infrared light returns composition data in seconds, with no contact and no sample preparation.

The KJT170 put six-filter near-infrared composition analysis into a handheld, battery-powered body. It measures several organic components at once, moisture, fat and oil, protein, starch, and more, from a non-contact reading taken in place, without carrying the sample to a benchtop analyzer.
The KJT170 stores up to 50 calibration channels, one per component, holds up to 99 time-stamped readings in memory, and offers sample, monitor, and average measurement modes. Two-level password protection guards stored settings, a tungsten lamp rated for roughly 20,000 hours supports long service life, and RS-232C connects the unit to a PC or printer. At about 1.1 kg, it travels easily. Every Kett instrument carries a One Year Total Care Warranty covering parts, labor, and specification compliance, with Maintenance Agreements available.
The KJT170 is no longer manufactured. For composition measurement on a production line, the replacement is our KJT700 Online NIR Composition Meter, which measures in place as product runs. For near-line or laboratory desktop measurement, the replacement is our KB270 Desktop NIR Composition Meter, which delivers the same multi-component analysis with higher precision on the bench.
