M-8MMitutoyo operates a policy of continuous improvement that aims to provide the customer with the benet of the latest technological advances.Therefore the company reserves the right to change any or all aspects of any product specication without notice.•With the HR-500, the hardness of even the inside wall of a pipe-shaped specimen can be tested without cutting the specimen in half. What is more, the HR-500 can perform 3 types of hardness tests, not only Rockwell and Rockwell supercial but also Brinell, by introducing our proprietary electronic control technology and providing the Brinell hardness testing load sequence.An inspection certicate is supplied as standard. Refer to page X for details.Refer to the Hardness Testing Machines (Catalog No. E17001) for more details.810-202HR-521810-203HR-522SPECIFICATIONS810-204HR-523 HR-500SERIES 810 — Rockwell Hardness Testing MachinesOrder No. 810-202/810-205*1 810-203/810-206*1 810-204/810-207*1ModelHR-521/HR-521LHR-522/HR-522LHR-523/HR-523LType of hardness testRockwell hardness/Rockwell Superficial hardness/Brinell hardness*2StandardsJIS B 7726 ISO6508-2 (ASTM E18)Preliminary test force (N)29.42 98.07Total test force (N)Superficial 147.1 294.2 441.3Rockwell588.4 980.7 1471Brinell1839 61.29 98.07 153.2 245.2 294.2306.5 612.9 980.7 1226 1839Test force controlAuto (load, duration, unload)Preliminary test force (handling support)Manual (automatic brake and automatic load sequence)Motor driven (manualoperation is also available)Total test force switchingSwitch operation touch panelTest force switchingSwitch operationTest force duration time0 to 120s (Can be set to any value in units of 1s.)Specimen maximumdimensionsHeight: 250mm (Long type: 395mm) Depth: 150mm (between indenter shaft and test machine main unit)Allowable inner diameterof pipe specimenMinimum hole diameter: 35mm (When the special specification indenter is used: 22mm)FunctionConversion function [HV, HK, HR (Rockwell hardness A, B, C, D, F, G / Rockwell Superficial 15T, 30T, 45T, 15N, 30N, 45N), HS, HB, Tensile strength]OK/NG judgment functionContinuous measurement function (for specimens of the same thickness)Cylindrical correction, spherical correction, offset correction, multi-point correction functionsStatistical calculation function Graph generation function (X-R control charts)External connection interfaceFor printer: Serial interface (compatible with the RS-232C standard), Digimatic interface, Centronics interfacePower supply100V AC, approx. 40VA or less, (120/220/240V AC set on shipment from factory.)External dimensionsMassBody: Approx. 250(W) x 670(D) x 605(H)mm, (Long types: 750(H)mm), Approx. 65kg (Long types: Approx. 75kg)Operation panel: Approx. 165 (W) x 260 (D) x 105 (H)mm approx. 0.75kgOrder No. and Models for long types: 810-205*1: HR-521L 810-206*1: HR-522L 810-207*1: HR-523L*1 To denote your AC power cable add the following suffixes to the order No.: A for UL/CSA, D for CEE, DC for CCC, E for BS, K for KC, C and No suffix are required for PSE. *2 For Brinell hardness testing, an indenter (option) and a measurement microscope are required.
