TCH121 Leeb hardness tester Portable Hardness Tester

I. Product Overview: TCH121 Portable Leeb hardness tester is a new multi-functional portable hardness testing equipment for hardness testing of metallic materials, have tested high precision, small size, easy to operate, easy to carry, wide measuring range of features It is based on the principle of Leeb hardness, measured Leeb (HL) hardness values ??after the program automatically converted into Brinell, Rockwell, Vickers, Shore hardness values, etc., you can configure a variety of test accessories to meet in a variety of test conditions and the environment, mainly for fast hardness testing of metallic materials, especially suitable for large parts and non-removable parts site hardness testing. Second, the functional characteristics: the hardness improvement TCH121 in adds the following features; ● with a high D-type impact device, to extend the life and improve the debugging accuracy. ● system can be tested six kinds of hardness (HV, HRC, HRB, HB, HV, HS); ● a machine can simultaneously with a variety of special-shaped impact device (D, DC, D + 15, C, DL, G) type; ● Automatic identification of impact device type (D, DC, D + 15, C, DL, G); ● You can set the upper and lower hardness deviation automatic sound alarm; ● screen with backlight, adjustable contrast; ● can store 48 to 350 groups of test data ; ● printer and host separable, more portable; ● increase of the test material (stainless steel) and expanding the test range; ● automatically detect the battery voltage, when the operating voltage is below the rated value, automatic alarm; ● can display battery level, convenient USB port charging; ● with a thermal printer, convenient to print the test results at any time; ● full Chinese menu, easy to operate; Third, the technical parameters: hardness scale HL, HRC, HRB, HV, HB, HS intensity range (only ferrous materials) ab: 370 ~ 2000 (10n / m) Accuracy relative error ± 0.8%, Repeatability error 0.8 (HLD = 800) can be set to deviation of the average, maximum, minimum, upper and lower computer output interface USB standard impact device High-performance D-type impact device other impact device DC / D + 15 / G / C / DL maximum hardness Britain workpiece measurement value 940HV (D / DC / DL / D + 15 / C impact device) 650HB (G impact device) test Minimum weight Minimum thickness direction at any measuring the radius of curvature of the workpiece Rmin = 50mm (with the shaped support ring Rmin = 10mm) measuring the workpiece stable support 2kg (0.1kg require coupling) measurement of the workpiece 3mm (G type of impact device: 10mm) measuring the workpiece Minimum impact means indentation depth see table a rechargeable battery power source NIMH12V, 1200mAh charger 9V75mA Charging time 2 hours (with overcharge protection) Operating temperature 0 ~ 40 ℃ Dimensions 270 × 86 × 47mm Weight 675g (including impact device and printer ) Leeb hardness test range (Table 1) material hardness scale impact device D / DC D + 15 CGE DL Steel and cast steel and cast steel HRC 17.9 ~ 68.5 19.3 ~ 67.9 20.0 ~ 69.5 22.4 ~ 70.7 20.6 ~ 68.2 HRB 59.6 ~ 99.6 47.7 ~ 99.9 37.0 ~ 99.9 HRA 59.1 ~ 85.8 61.7 ~ 88.0 HB 127 ~ 651 80 ~ 638 80 ~ 683 90 ~ 646 83 ~ 663 81 ~ 646 HV 83 ~ 976 80 ~ 937 80 ~ 996 84 ~ 1042 80 ~ 950 HS 32.2 ~ 99.5 33.3 ~ 99.3 31.8 ~ 102.1 35.8 ~ 102.6 30.6 ~ 96.8 Steel Forged HS 32.2 ~ 99.5 CWT, ST alloy tool steel HRC 20.4 ~ 67.1 19.8 ~ 68.2 20.7 ~ 68.2 22.6 ~ 70.2 HV 80 ~ 898 80 ~ 935 100 ~ 941 82 ~ 1009 Stainless steel stainless steel HRB 46.5 ~ 101.7 HB 85 ~ 655 HV 85 ~ 802 GC.
