ETM-01 Small-size electronic hardness tester

ETM-01 Small-size electronic hardness tester 0

Electronic small-size hardness tester ETM-01 in accordance with TU U 33.2-23113534-003: 2008 produced by JSC "MINETEK" passed State acceptance tests and entered in the state register of measuring equipment under No. У 1913-04. To date, this is the only domestic device of this class (certificate No. UA - MI / 1p - 1569 - 2004 of 10.11.04).

The hardness tester is designed for non-destructive testing of hardness of metals in production and laboratory conditions on the Brinell, Rockwell and Vickers scales. The principle of the hardness meter is dynamic. The hardness meter is manufactured in the versions shown in the table.

Features of hardness meter ETM-01:

Measuring hardness of complex shape parts and large-sized products having hard-to-reach measurement zones, with different spatial positions of the sensor;
high performance, easy operation and maintenance;
diagnostics of the operated equipment with the purpose of an estimation of its residual safe resource;

MINETEK CJSC performs maintenance, repairs (including warranty), primary and periodic verification (calibration) of hardness meters ETM-01.

Main technical characteristics

Limits of the permissible error of hardness measurement during verification (calibration) of the hardness meter according to the working standards of hardness units of the 2nd category according to DSTU 3870-99, DSTU 3869-99 and GOST 8.516-2003 (hardness measures of MTB, MTP, MTB type) in all ranges of measurement and The range of solid hardness readings for measurements at each hardness measure is given in the table.
