CV Portable Analogue Hardness Tester
- CV Instrumatic
A fully mechanical instrument of the highest precision, robust, and maintenance free. The large clearly marked dials on these unique
instruments cover a full range of hardness values in Vickers, Brinell, Rockwell A, B, C, covering national and international standards.
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 (0.005").
Operation and Use
The simplicity of the tester enables it to be used in almost any direction, 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 UKAS certified reference test block supplied with each
instrument. Each tester is supplied complete with case and detailed operating instructions.
Features

• Precision Instrument
• Able to test even thin materials due to low
penetration of indenter (0.25mm and above)
• Bench stand available for testing small components
