Legacy desktop single-kernel grain and rice moisture meter. Replaced by the PQ520.
The PQ510 was the second-generation desktop single-kernel moisture meter from Kett, refining the PQ500 design with expanded rice and barley calibration coverage while keeping the same desktop chassis. Current production has moved to the PQ520, which introduced a new chassis design with faster throughput, USB output, universal voltage, and significantly expanded calibrations.
Refined single-kernel design: DC resistance measurement of each kernel, with average moisture, kernel count, and LED histogram display. Sample sizes selectable from 10 to 1,000 kernels.
Expanded calibrations vs. PQ500: Added polished rice and naked barley alongside the PQ500's paddy rice, brown rice, wheat, and barley calibrations.
Service and replacement support: Service and parts availability is limited for this legacy unit. Contact Kett for current options.
Legacy desktop single-kernel grain and rice moisture meter. Replaced by the PQ520.
The PQ500 was Kett's first-generation desktop single-kernel moisture meter, measuring kernels individually and building a moisture distribution histogram for harvest timing, drying optimization, and lot consistency verification. Current production has moved to the PQ520, which offers expanded calibrations, faster throughput, USB output, and universal voltage.
Original single-kernel design: Resistance-based measurement of each kernel, with average moisture, kernel count, and 21-segment LED histogram display.
Four factory calibrations: Wheat, barley, rice, and paddy rice. Sample sizes selectable from 10 to 1,000 kernels.
Service and replacement support: Service and parts availability is limited for this legacy unit. Contact Kett for current options.
Legacy desktop single-kernel corn moisture meter. No direct replacement in the current Kett lineup.
The PQ100 was Kett's single-kernel moisture meter for corn, measuring kernels individually using DC resistance and reporting average moisture, standard deviation, and a moisture distribution histogram. The two-piece design used a separate handheld controller with integrated thermal printer connected to the main measurement body. Corn processors and grain operations used it to detect uneven drying and verify lot consistency at the per-kernel level.
Corn-specific single-kernel design: DC resistance measurement of individual kernels, with measurement range of 9–40% and sample sizes from 11 to 599 kernels.
Two-piece form factor: Main measurement body plus separate handheld controller with LED display, keypad, and integrated thermal printer.
No direct replacement: The current Kett single-kernel measurement option is the RX inline series, automated for installed grain handling systems rather than desktop operation. Contact Kett for guidance.
