INSIZE ISH-MRD200-U Automatic Digital Rockwell Hardness Tester
Are you looking for a robust, fully automatic digital Rockwell hardness tester built to deliver accurate, repeatable hardness measurements across a variety of metals? The INSIZE ISH-MRD200-U is designed for use in quality control labs, manufacturing environments, and R&D settings, this tester combines automatic load control, high memory capacity, and wireless/USB data output. Its capacity to convert readings to other scales and to alarm on tolerance limits makes it ideal for both production monitoring and precision testing.
Key Features
-
Automatic Load Control: Handles automatic loading, hold (dwell), and unloading cycles to ensure consistent and reproducible test results.
-
Wide Rockwell Scale Support: Supports standard Rockwell scales — HRA, HRB, HRC, HRD, HRF, and HRG — and can optionally handle HRE, HRH, and HRK with special indenters.
-
Large Test Force Range: Provides multiple force levels — preliminary 98 N (10 kgf) and test forces of 588 N (60 kgf), 980 N (100 kgf), and 1471 N (150 kgf) — to support a variety of material hardnesses.
-
Adjustable Dwell Time: Load dwell time can be set between 1 and 99 seconds to suit different material behavior.
-
High Resolution: Displays hardness results with a fine resolution of 0.1 HR, giving precise readings.
-
High Memory Capacity: Stores up to 500 (or in some sources 1,000) test values, making it easy to review, average, or export data.
-
Data Output: Supports both wireless (printer) and USB connectivity, allowing test results to be transferred seamlessly.
-
Tolerance Testing & Alarm: Features low/high limit alarms so you can flag parts that fall outside acceptable hardness ranges.
-
“Lock” Function for Soft Materials: For soft or unstable materials (e.g., plastics), the lock feature captures stable hardness values automatically.
-
Scale Conversion: Automatically converts Rockwell results to Vickers (HV) and Brinell (HB), enabling flexible reporting.
-
Manual Stage Elevation: The anvil is adjusted manually, giving precise control over sample positioning.
-
Built-In Rechargeable Power: The display/control unit runs on a built-in rechargeable battery.
-
Durable Construction: Sturdy design with dimensions of ~520 × 160 × 700 mm and a weight of about 60 kg.
