Hardness Tester

Description

The **Instrumatic Universal Hardness Tester MK4** is a robust, high-precision, fully mechanical portable instrument designed for accurate hardness testing across a wide range of materials. Engineered for quality control and on-site inspections, it adheres to British, American, and German standards, delivering reliable measurements without the need for a power supply. Its compact dimensions of approximately 3" x 6" (75mm x 150mm) ensure portability and ease of use in various orientations, preferably vertically, without compromising accuracy.

### Key Features:
- **Versatile Hardness Scales**: Features large, clearly marked dials displaying hardness values in Vickers (HV: 20–1000), Brinell (HB: 40–600), Rockwell A, B, C (RHA: 40–85, RHB: 50–100, RHC: 20–70), and Kp/mm² (35–140), covering a comprehensive range of testing needs.
- **Mechanical Operation**: Utilizes preloaded springs to apply a precise 15kg load to a diamond indentor, with a maximum penetration depth of 0.125mm (0.005"). The direct mechanical linkage ensures accurate readings transmitted to the dial face.
- **Ease of Use**: Simple operation involves depressing the grips to apply force, allowing hardness values to be read directly from the appropriate scale. Excellent repeatability is achieved, and calibration can be verified using the included UKAS-certified test block.
- **Durability and Low Maintenance**: Robust construction requires no regular servicing. A replaceable diamond indentor can be easily fitted using the provided tool, eliminating the need for costly repairs or recalibration.
- **Accessories**: Comes complete with a carrying case, UKAS-certified test block, adjusting keys, and detailed operating instructions. Optional accessories include a precision bench stand with a vee base for round parts and a magnetic holder for testing large ferrous surfaces like lathe beds or milling machine tables.

### Applications:
Ideal for quality control engineers and inspectors in industries such as aerospace, automotive, and manufacturing, the MK4 is perfect for on-site testing of materials like steel, aluminum, brass, and copper. Its ability to test extrusions, tubing, flat stock, and large finished surfaces makes it a versatile tool for production and laboratory environments.

### Technical Specifications:
- **Code No.**: POR0004
- **Scales**:
- Kp/mm²: 35–140
- Brinell: 100–400
