Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Moisture Measurement: Provides precise moisture content readings with ±0.1% or ±0.5% accuracy for grains, seeds, and agricultural products like corn, wheat, rice, and soybean.
  • Temperature Monitoring: Dual-display LCD screen shows real-time moisture percentage and ambient temperature (e.g., 29.9% moisture, 16°C temperature).
  • Grain Type Customization: Dedicated "Variety" button allows users to select specific crop types (e.g., paddy, barley, seed cotton) for calibrated measurements.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a rugged, corrosion-resistant metal body, you can ensure durability in harsh outdoor environments. Outlast plastic-bodied models*

  • 2. Intuitive Interactive Design

    • With dedicated buttons for grain selection, voice output, and quick measurements, you can operate the device without technical expertise. Simpler than models requiring manual calibration*

  • 3. Precision Performance Parameters

    • With ±0.1% accuracy, you can achieve lab-grade precision in moisture readings. 2x more accurate than standard ±0.5% models*

  • 4. Versatile Scenario Solutions

    • With presets for 14+ grains (corn, wheat, rice, etc.), you can adapt to diverse agricultural needs. Outperforms single-purpose devices in multi-crop farms*

  • 5. Compliance with Industry Standards

    • With adherence to food safety and agricultural measurement standards, you can ensure reliability for professional use. Certifications available upon confirmation from the manufacturer*

Supplier's note

  1. Technical Breakthroughs:

    • Pro Model Accuracy: The ±0.1% precision triples the industry standard, enabling safe storage decisions for high-value crops like rice.
    • Voice Output: Hands-free operation improves safety in noisy environments (e.g., grain silos).
    • IP67 Waterproofing: The Pro Model’s submersion resistance ensures reliability during outdoor rain or washdowns.

  2. Version Selection Guidance:

    • Farmers/Small Holders: Base Model suffices for routine checks where ±0.5% accuracy is acceptable.
    • Agro-Processors: Advanced Model suits medium-scale operations needing faster (20% quicker) and more durable tools.
    • Export/Quality Labs: Pro Model’s triple-precision and waterproofing are critical for compliance with international standards.

*Pro Model’s speed is 50% faster than Base Model.
