CLARK CR Series Rockwell type Hardness Testers

Features:

- HIGH ACCURACY & RELIABILITY

- HARDNESS CONVERSION

Hardness conversion for many scales are displayed on the panel in compliance with ASTM (E-140), SAE (J-417b), and JIS.

- OK/NG CRITERIA

Capable for setting upper and lower limits and OK/NG display

- PLASTIC MEASUREMENT MODE AS STANDARD FUNCTION

Specific measuring method for plastic in compliance with ASTM and JIS is activated by one-touch operation.

-STEADY LOAD SPINDLE MECHANISM

Two ball guides are adopted on upper and lower parts of load spindle, providing constant and accurate measurement on cylindrical and spherical surface.

- EASY "ZERO" SETTING WITH LEVEL METER AND ELECTRONIC SOUND

The minor load can be set easily without watching the digital display by means of the LED level meter and electronic sound.

- AUTOMATIC START LOADING

In "AUTO" measuring mode test load is automatically applied once the minor load has been set (290.0 to 299.9 on the digital display). Automatic load application does not start if the minor load exceeds the range (over 300.0 on the digital display). Also capable of manual start.

- RS-232C OUTPUT AS STANDARD

In addition to CENTRONICS output, a RS-232C outputs is provided for computer or printer capabilities.

- USER-FRIENDLY OPERATION PANEL

For convenience, all test conditions (measuring scale, dwell time, conversion scale, etc.) can be easily accessed on the durable front membrane operation panel.
