Portable Hardness Tester "INSTRUMATIC" ™
A fully mechanical instrument of the highest precision,
robust, and free from normal maintenance
|
The large clearly marked dials on
these unique instruments cover a full range of hardness values in Vickers,
Brinell, Rockwell A, B, C, and Kp/mm ² covering the British, American
and German specifications
The Instrument
The system is entirely mechanical employing the use of special pre-loaded
springs which provide a load of about 15kg to the diamond. Maximum penetration
of the diamond into the specimen is 0.125mm (.005").
Operation and Use
The simplicity of the tester enables it to be used in almost any direction,
(preferably vertically), without affecting accuracy. It can be used "˜on
site"™ with complete success. The grips are depressed to the fullest
extent by using the palms of the hands and the hardness value can be read
off the appropriate scale. Repeatability is excellent and the calibration
can be checked by the user against a reference test block supplied with
each instrument. Each tester is supplied complete in a case with detailed
operating instructions.

Diamond Indentor
The instrument does not require any regular servicing. Should the diamond
indentor become damaged, a new indentor can simply be fitted using the
small tool supplied with the instrument.
Bench Stand
Bench stand with vee base for round parts, available as an option.
Magnetic Holder A magnetic holder is available for checking the hardness of large ferrous
finished surfaces such as lathe beds, milling machine tables and large
surfaces which cannot be easily checked by hand.
