Single Kernel Grain Moisture Tester PQ-520

The PQ-5205 Single Kernel Grain Moisture Tester provides fast and continuous measurement of moisture content, measuring one kernel at a time. It can determine the moisture distribution of a large sample, helping to evaluate drying conditions and monitor moisture variation during grain processing.

The instrument is easy to operate and automatically displays the average moisture content after measurement. It can also display the moisture distribution as a histogram for easy evaluation.

Key Features

  • Single Kernel Measurement — Measures the moisture content of individual kernels one at a time.
  • Moisture Distribution Analysis — Displays moisture variation within a sample using a histogram.
  • Fast Continuous Measurement — Measures 100 brown rice kernels in less than 40 seconds.
  • Selectable Sample Size — Supports sample sizes from 10 to 1,000 kernels.
  • Average Moisture Calculation — Automatically calculates and displays the average moisture content.
  • Statistical Analysis — Supports average and standard deviation calculations in printout mode.
  • Multiple Grain Applications — Suitable for milled rice, brown rice, paddy rice, wheat, barley, and naked barley, depending on the selected program.
  • Automatic Temperature Compensation — Compensates for instrument temperature variations.
  • Digital Histogram Display — Helps users assess moisture consistency and identify uneven drying.
  • Data Output Options — Supports an optional printer through RS-232C and computer connectivity through USB.
  • Easy Sample Handling and Cleaning — Features a sample feed opening, a collection tray, and a side access door for cleaning.
