Instrument in use on pipe cross section

Requires minimal maintenance. Ideal for inspectors & quality control for engineers for on-site checking.

Preferably used in a vertical position, the Electromatic may be used in almost any direction— even on circular sections—without affecting accuracy.

The scale is in Rockwell C and is easily read on the large digital readout. Complies with American, British and German standards.

• Mechanically operated with an electromechanical readout, the instrument utilizes a series of special preloaded springs, providing a load of approximately 15kg to the indentor.
  
• It is virtually impossible for the operator to overload or influence the reading by varying hand pressure.
  
• When conducting a hardness test, the springs operating against the diamond assembly are balanced against the hardness of the specimen. The harder the material under test, the more movement is effected between the diamond point and the datum face of the unit. This movement is interpreted by a specially calibrated linear displacement transducer which encodes the linear movement of the diamond and transmits it to the electronics where the hardness value is produced as a digital readout.
  
• Tester with folding handles weighs approximately 5lb/2.25kg.
  
• Maximum penetration of diamond into the specimen is .005"/.125mm.
  
• Offers excellent repeatability. Check calibration against supplied reference block.
  
• For accurate readings, avoid coarse finishes on machined surfaces. Specimens to be tested must be free of rust and scales.
  
• Zero setting is achieved by gently depressing the hand grips until digital readout switches on. When movement ends, the reading is taken. Automatically shuts off when hand grip is released.
  
• Operates on a 9 volt battery (approximate life of two years). End of battery life is signaled by ‘LOW-BATT’ in corner of the display.
  
• Price includes calibrated test block, indentor key, instruction book and wood case.
