Superior Construction for Reliable MeasurementsCrafted from powder-coated stainless steel, this Grain Hardness Tester offers robustness and longevity. The adjustable jaw clamp secures specimens of typical grain size, ensuring consistent positioning throughout the testing process. The transparent safety shield provides added protection, allowing you to observe tests safely.
Accurate, User-Friendly OperationEngineered for both routine quality control and research use, the machine uses a manual lever/press mechanism, giving users direct control over force application. Its analog/digital display delivers instantaneous, highly precise readings, while external calibration ensures ongoing measurement accuracy.
Versatile Applications in Agriculture and ResearchWith compliance to ISO/CE standards and a compact, portable design, this tester serves exporters, importers, manufacturers, suppliers, and traders across India. Its compatibility with various grains and single-grain measurement capacity makes it indispensable for testing grain hardness in laboratories and agricultural facilities.
FAQs of GRAIN HARDNESS TESTER:
Q: How do I operate the Grain Hardness Tester for a sample measurement?
A: To perform a test, place a single grain specimen in the adjustable jaw clamp, close the transparent safety shield, and manually apply force using the lever/press mechanism. The device will display instantaneous measurement on its analog/digital interface.
Q: What types of grains can be tested with this device?
A: The tester is designed for typical grains such as wheat, rice, and other similar specimens, supporting single grain hardness determination within a 1-50 N range.
Q: When should I calibrate the Grain Hardness Tester?
A: External calibration is recommended before starting multiple tests or after relocating the device to ensure ongoing measurement accuracy and compliance with ISO/CE standards.
Q: Where can the Grain Hardness Tester be used?
A: Its portable, bench-top design makes it suitable for laboratories, quality control rooms, research centers, and agricultural facilitiesany location requiring grain hardness determination.
Q: What benefits does the transparent safety shield provide?
A: The transparent safety shield protects the user from debris or accidental contact during testing while allowing clear observation of the specimen throughout the process.
Q: How does the tester ensure measurement accuracy and reliability?
A: The tester uses an external calibration system, precise force application via a manual lever, and delivers results with 0.1 N accuracy and a 0.01 N resolution.
Q: What is the process for routine grain hardness testing?
A: Place a grain in the adjustable clamp, close the safety shield, apply force manually, and read the hardness value instantly from the analog/digital display. For best results, follow calibration procedures and ensure environmental conditions are within specified ranges.
