Metal hardness measurement device (UNI-T UT347A (Leeb Hardness Tester

The UNI-T UT347A device is a portable and accurate Leeb hardness tester, specifically designed for on-site (field) hardness testing, and is particularly suitable for large equipment. Main features: portability and thermal printing: the device is precise and portable, supporting thermal printing for immediate results (uses 57mm wide thermal paper), making it ideal for testing the hardness of massive equipment such as rotating turbine shafts, pressure vessels, and turbine assemblies. Multiple measurement ranges: measures in real-time 6 types of hardness values: (HL, HB, HRC, HRB, HV, HS), in addition to tensile strength measurement. Versatile impact device: can be equipped with up to 7 different impact devices (D-type impact device as standard), with automatic impact device identification without the need for calibration when replaced. Screen and camera: features a 2.8-inch TFT color display (320x240 pixels). Includes a camera function (640×480 pixels) to store up to 900 BMP format images for recording test details. Data storage and analysis: stores up to 900 data sets. Supports Bluetooth (Bluetooth APP) and USB connectivity, with PC analysis software available. Measurement modes and directions: 4 measurement modes: statistical, multi-unit, line chart, bar chart (Histogram). Statistical measurement: calculates (maximum value / minimum value / average). Impact directions: 5 possible directions (0 - 45 - 90 - 135 - 180). Additional specifications and features: material selection: supports measuring a wide range of materials including: steel and cast steel, alloy tool steel, stainless steel, forged steel, cast aluminum alloys, copper-zinc alloys, copper-tin alloys, gray cast iron, ductile cast iron, and pure copper. Alert functions: features automatic alarm when exceeding upper and lower limits (with a three-color LED indicator). Lighting and power: built-in LED flashlight. Rechargeable lithium polymer battery (3.7V, 2500mAh). Charging via USB Type-C connector (DC5V 2A power adapter). Other features: directional sound, adjustable backlight brightness, and adjustable automatic shutdown function. Application fields: widely used in industries such as petrochemicals, electrical power, automotive, shipbuilding, and machinery manufacturing. Approximate weight of the device (with packaging): 5.5 kilograms.
