Supported Applications
The Omega HGM68 Handheld Digital Grain Moisture Meter is designed for measuring moisture content in grains, seeds, and other organic materials. The series utilizes a dielectric measurement method to determine values in packed grains, foodstuff, and feedstuff.
• Grains
• Seeds
• Organic Materials
• Foodstuff
• Feedstuff
Operating Conditions & Performance
The HGM68 operates within an ambient and process temperature range of 14°F to 131°F (-10°C to 55°C). The instrument measures moisture content from 0 to 20% with a resolution of 0.1%. Accuracy is specified as ±3% for moisture content and ±0.8°F (±0.4°C) for temperature. Repeatability is listed at 0.1, and the response time is approximately 30s.
Configuration Options
The series features a strong, lightweight, high-impact ABS-plastic housing designed to fit comfortably in either hand. It includes a digital display providing exact readings without requiring an operator or extra display unit. The device performs self-calibration upon power-on, indicated by two beeps.
• Display: 4 digits, 4" LCD (Liquid Crystal Display)
• Housing Material: ABS-Plastic
• Power Source: 4 AA Alkaline Batteries (included)
• Included Accessories: Battery Compartment Cover and Hard Carrying Case
Key Product Differences
The HGM68 model is configured with a probe featuring needles for insertion into the material. The instrument includes a MATERIAL SELECTION switch to select between foodstuff or feedstuff types prior to measurement. Users are advised that moisture content readings may change if the needles remain in the grain for an extended period of time.
