| 1、 Overview:
KY-MH-210 is an improvement made in the hardness measurement mechanism and circuit performance based on the company's existing Leeb hardness measuring instrument products. After undergoing factory aging treatment for at least 72 hours, the product has high accuracy, stable measurement values, and strong functionality. The advantage of MH210 lies in the combination of two data processing solutions: a portable Chinese self powered thermal high-speed printer and user-friendly PC connected processing software. On site printing is convenient, fast, quiet, and flexible, meeting the on-site needs of different personalized users. Low power design, connected to computer for data exchange and storage. Low power design, no less than 100 hours of standby time, powered by AA size 5 ordinary battery, easy to carry, and flexible to replace. Suitable for work sites and field operations. 2、 Features:
1. A fully sealed metal casing that is compact, portable, and highly adaptable to harsh operating environments. It has strong resistance to vibration, impact, and electromagnetic interference, and is sturdy and durable;
According to the principle of Leeb hardness measurement, various metal materials can be tested. Measurement range, limited to measuring the shape of the workpiece, supports 360 degree measurement direction, and has a software calibration function for startup indication. The data can be applied to different industry specifications and standards.
3. Supports multiple hardness tester systems including Rockwell (HL), Brinell (HB), Rockwell B (HRB), Rockwell C (HRC), Rockwell A (HRA), Vickers (HV), and Shore (HS). Parallel conversion between hardness hardness hardness before and after measurement.
4. Good compatibility performance, seven types of impact devices need to be calibrated for automatic recognition. The price of the special-shaped impact device and series of special-shaped support rings is reasonable, meeting the maximum needs of different customers and fields.
5. Chinese large screen 128 * 84 graphic dot matrix LCD display with EL backlight support, convenient for use in low light environments.
6. The Chinese menu style operation of the host panel is reflected in the humanized circuit design, and the one click switching of materials and hardness is simple and convenient.
7. Equipped with a commonly used 232 plug and play interface, the standard configuration includes PC data processing software for connecting to a computer and a miniature on-site high-speed thermal printing device. Convenient and flexible real-time processing of on-site data.
8. Large capacity storage of up to 500 sets of hardness measurement data (impact frequency 32-1), each set of data including single measurement value, average value, measurement date, impact direction, frequency, material, hardness system, and other information. Using software to connect to a computer can also achieve storage.
9. The upper and lower limits of the hardness value can be pre-set, and an automatic alarm will be triggered if it exceeds the range, making it convenient for users to conduct batch testing.
10. Support "Steel" materials. When testing "Steel" specimens with a D/DC impact device, the HB value can be directly read and manually checked in the table.
11. It has functions such as automatic sleep and automatic shutdown, low-power design, powered by 2 AA No. 5 batteries, easy to replace, and strong battery performance.
12. Two year free warranty, with qualified prices for vulnerable and consumable parts.
13. Dimensions: 132 X 76.2
14. Whole machine weight: 345g 3、 Applicable materials:
Steel and cast steel, alloy tool steel, stainless steel, gray cast iron, ductile iron, cast aluminum alloy, copper zinc alloy (brass), copper tin alloy (bronze), copper, forged steel 4、 Main application areas:
