The simplicity of the Fowler 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 directly. There is no need for microscopic measurement of the indentation
or reference to conversion tables.

Operators cannot overload instrument or influence reading by varying applied hand pressure. Reading obtained is completely dependent on the specially designed pre-loaded springs in the tester. Repeatability is excellent and calibration can be checked against reference test block supplied with each instrument. If necessary, the indenter adjusting bushing can easily reset to give the exact test block reading.

• Suitable for use on ferrous and non-ferrous metals from small diameter rods to large surfaces.
  
• Special bases available for use on small diameters or large radii.
  
• Stand accepts tester in a firm clamp, and table in stand is raised vertically to meet diamond indenter by means of pressure on a simple lever device.
  
• Special "V" base on each stand checks the hardness of round parts.
  
• Overall dimensions of 3" x 6" (75mm x 150mm) enables the instrument to be used universally and conveniently by Quality Control Engineers and inspectors, etc.
  
• Tester is entirely mechanical, using special pre-loaded springs which provide a load of about 14.3 lbs. (6.5 kg) for the 53-760-001, 002 and 005 to the diamond.
  
• For 53-760-006 the load is 8.8 lbs. (4 kg).
  
• For 53-760-007, load is 35.2 lbs. (16 kg).
  
• When taking hardness reading, springs operating against diamond assembly are balanced against hardness of specimen, i.e., the harder the part being tested, the more movement is affected between diamond point and datum face of the unit.
  
• Movement is transmitted through a direct mechanical linkage to the gage head where a movement of .0001" (.0025mm) at the diamond is amplified to approximately .250: (6.35mm) of rotary movement at the tip of the pointer. Maximum penetration of diamond into specimen is .005" (.125mm).
  
• The Fowler Tester is supplied with detailed operating instructions, a test block and adjusting wrenches.
  
• Price includes a hardwood case
