Portable NIR Moisture Meter: Non-Contact Readings You Carry to the Material
Point the instrument at a surface from about 150 mm away and read moisture content in roughly two seconds. A battery-powered handheld with a built-in distance-indicator beam, it measures without contact and without sample preparation, so finished and delicate surfaces stay intact.

The KJT100 brought near-infrared moisture testing into a handheld, battery-powered instrument. Point it at a surface from about 150 mm, and it reads moisture content in roughly two seconds, with no contact and no sample preparation. A built-in distance-indicator beam sets the correct standoff every time.
The KJT100 stores up to 50 calibration channels with linear, quadratic, or cubic curve fitting, 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 KJT100 is no longer manufactured. The upgraded instrument is our KJT130 Handheld NIR Moisture Meter, which carries forward the same non-contact, portable measurement with higher precision and modern connectivity.
