HR-511/521/522/523
SERIES 810 – Rockwell Type Hardness Testing Machines
FEATURES
Multiple test force generation for Rockwell, Rockwell Superficial and Brinell hardness.
Dolphin-nose indenter arm for easy reach of interior (min. Ø40mm/ Ø22mm*)
and exterior surfaces.
* When using an optional diamond indenter (19BAA292).
Real time electronic test force control for accurate loading. This perfectly eliminates
load force overshooting.
Indenter escape function for continuous testing at fixed table position. This eliminates
instability caused by the table retraction.
Auto-stop elevation table and automatic preliminary test force loading to provide
stable test force generation.
Compact body with large working space.
Various data output, RS-232C, Centronics and Digimatic Code.
Control Unit
Durable sheet switch type
Durable sheet switch operation with LED display.
Remote selection of the test force linked to the hardness scale selection.
Powerful statistical processing and 1024 data memory.
Data offset
OK/NG tolerance judgement.
SPC calculation (No. of data, max./min./mean values, range, upper/lower limit values,
standard deviation (n, n-1), No. of passing/defective)
Touch screen type
Touch screen operation with a back-lit LCD graphic display.
Remote selection of the test force linked to the hardness scale selection.
Choice of message language in English, German, French, Spanish, Italian and Japanese
for user friendly operation.
Cylindrical and spherical surface compensation.
Data offset
Complete conversion to other hardness scales (HV, HK, HRA/B/C/D/F/G/15T/30T/45T/15N/
30N/45N, HS, HB (HBS)) or tensile strength.
Powerful statistical processing with flexible data point editing and 1024 data memory.
Measured data editing
OK/+/-NG tolerance judgement.
SPC calculation (No. of data, max./min./mean values, range, upper/lower limit values,
Standard deviation (n, n-1), No. of passing/defective)
Histogram and X-R chart
