Desktop single-kernel testing for moisture distribution. Measure kernels one at a time and see how the moisture is spread across your sample.
Average moisture hides the variation that matters. The PQ520 measures each kernel individually and builds a distribution histogram, giving rice mills, grain processors, and harvest operations the information they need to time harvest, dial in drying, and verify lot consistency. Pour a sample, press start, and the average moisture and full distribution display on screen.
Per-kernel measurement: Each kernel is tested individually, then results combine into an average plus a full moisture distribution histogram.
Sustained throughput: Process 10 to 1,000 kernels per sample at roughly 150 kernels per minute, built for repeated measurement campaigns rather than one-off field checks.
Rice industry focus, extended: Calibrations cover long and short grain milled, brown, and paddy rice, jasmine, parboiled, sticky rice varieties, plus wheat and barley.
Data ready: RS-232C output for the optional thermal printer; USB output with optional PDL-01 data logger software for direct PC capture.
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.
