Introduction: The GWJ-2 digital display grain hardness tester is an essential tool for scientific research and teaching in the agricultural industry. It utilizes advanced force measurement technology to test the hardness of various grains such as wheat, rice, paddy, and feed particles. The instrument boasts high testing accuracy, intuitive digital display, high resolution, and is both durable and reliable. Its sleek design allows for use both at acquisition sites and on laboratory benches. Functions: Digital Display: Easy to read with high accuracy. Lightweight and Portable: Small size, easy to carry. Dual Units: Switch between Kg and N. Battery Protection: Short circuit, leakage, and overload protection with a 3.7V lithium battery that powers off automatically within 10 minutes. Two Measurement Modes: Real-time and peak value modes. Features: Model: GWJ-2 Maximum Load: 20kg, 196N Load Division Value: 0.01kg, 0.1N Load Cell: Internal Accuracy: 2% Power Supply: 3.7V lithium battery Charging Time: 4-6 hours Battery Life: Continuous use for about 15 hours, 300 charging cycles Charger Input: AC 100-240V 50/60Hz Charger Output: DC 5V 1000mA Working Temperature: 5 to 35 Transport Temperature: -10 to 60 Relative Humidity: 15% to 80% RH Working Environment: Free from corrosive media How to Use: Turn On: Power on the instrument and enter the measurement interface. Select either real-time mode or peak value mode as required. Position Grain: Place the grain vertically on the platform. Rotate the wheel until the grain breaks, while the digital display shows the test value. Reset: For additional tests, clean the platform and press "ZERO" to reset the screen. Repeat the process. After Use: Clean the platform, power off the device, lower the clamp, and store all accessories in the tool box. Precautions: Environment: Suitable for ambient temperatures between -40 and +60 with relative humidity not exceeding 80%. Handle with Care: Avoid impacts and falls to maintain precision. Clean the device after use. No Unauthorized Disassembly: Parts are pre-adjusted for optimal performance. Do not disassemble.
