1. Overview
1.1 HMR Advantages

Wide measuring range based on the principle of
Leeb Hardness testing theory. Leeb Hardness of
all metallic materials can be measured.

Large screen (128 x 64 dot matrix LCD) showing
all functions and parameters.

Testing at any angle, even upside down
 With EL background light

Direct display of hardness scales HRB, HRC,
HV, HB, HS, HL
 Seven impact devices are available for special
applications. Automatical identification of type of
impact devices
 Large capacity memory can store 500 groups,
information including single measured value,
mean value, testing date, impact direction,
impact times, material, hardness scale etc.

Upper and lower limit can be preset. It will alarm
automatically if the result value is exceeding the
limit.

Battery information: rest capacity of battery is
indicated.
