KETT Grain Moisture Meter FV223 – Japanese‑Made Handheld Precision Meter. Measure grain moisture with confidence using the KETT FV223, a high‑precision, handheld moisture meter made in Japan. It gives you fast, accurate readings for grains, rice, and seeds—whether you’re in the field, warehouse, or lab. You get real‑time data to prevent spoilage, optimize drying, and ensure quality control.

Key Features & Benefits
Fast, Accurate Measurement — FV223 delivers moisture results within seconds using an electrical resistance (or similar proven) method. You can trust its accuracy to ~±0.5 % (in standard moisture ranges).
Multiple Grain Types Supported — Works with paddy, brown rice, milled (polished) rice, wheat, barley, and possibly other seeds. (If you have a table of calibration curves, use that.)
Automatic Temperature Compensation — The meter corrects for sample temperature (and sometimes ambient temperature) so moisture readings stay reliable regardless of heat conditions.
Clear, Backlit Digital Display — The LCD displays moisture %, grain type, and sometimes average value, letting you see readings even in low light.
Compact & Portable — Battery‑powered (typically AA or similar), lightweight construction; you can carry it into the field or store it easily.
Durable & Field‑Friendly — Robust housing, non‑slip or textured grip, sample tray and spoon/tweezers included; built for daily use.

Seed producers ensuring seed moisture is proper for germination & storage
Traders & exporters who need moisture content documentation for contracts
Agricultural research labs & extension agents for field testing
⚠️ Tips for Best Usage
Always calibrate the meter for the specific grain type you’re testing.
Use sample volumes per the manufacturer’s instructions for consistent grinding or sample preparation.
Avoid abrupt changes in temperature of the samples—allow them to acclimate if possible for more accurate readings.
Keep the sample and the meter clean; residue or dust can affect electrical resistance and reduce accuracy.
