AUTOMATIC SCRATCH HARDNESS TESTER SIIN - 705

Mechanised Tester is dedicated to coating hardness evolution based on scratching resistance method.

A test panel is clamped to a slide which slowly withdraws the panel while a needle scratches the surface. Tests are conducted either on a ‘go/no go’ basis using a single specified load or by increasing the load to determine the minimum load at which the coating is penetrated. The systems indicate scratch by means of a buzzer and indicator which turn on when the needle touches the base metal.

A Voltmeter indicates the contact, when the needle touches the base metal.

The automatic systems disengage the needle from the panel when returning to home position.

 

Features:

  • ◆ Audio & Visual Alarm.
  • ◆ Auto Scratch & Reverse.

Technical Parameters:

  • ◆ Motor speed: 60 mm / minute.
  • ◆ LOAD: Up to 5 Kg.
  • ◆ Test Panel size : 150 x 100 x 1.25 mm.

Conforms To:

ASTM D5178, D2197, BS 3900;E2, ISO 1518, IS : 101.

 

Supplied With:

One tungsten carbide Needle, One Set 5kg.Weight,

One weight Holder, Calibration Certificate Traceable to NABL.

PENCIL HARDNESS TESTER SIIN - 501

The pencil hardness tester uses the varying hardness values of graphite pencils to evaluate a coating’s hardness. The pencil lead prepared beforehand using the special sharpener and abrasive paper, is inserted into the tester and pushed over the smooth & flat coated surface.

The lowest hardness value of the pencil which marks the coating determines the coating’s hardness rating.

The SIIN-501 has been designed to ensure that the cylindrical pencil lead is maintained at a constant angle of 45° and exerts a force of 7.5N (750 gm).

 

Features:

  • ◆ Small volume, light weight.
  • ◆ Use at the laboratory and construction site.

Technical Parameters:

  • ◆ Load on the point of pencil:750±5g.
  • ◆ Constant angle of 45°.
  • ◆ Overall dimensions:120×75×60mm(L×W×H).
  • ◆ Weigh: 2.3kg.

CONFORMS TO

ASTM D 3363,BS 3900-E19,EN 13523-4,ISO 15184,JIS K 5600-5-4, IS:101.

 

Spare pencils: 7B,6B,5B,4B,3B,2B, HB,7H, 6H,5H,4H, 3H,2H,F grades(Optional).

BUCHHOLZ INDENTATION HARDNESS TESTER

Indentation Tester is used to evaluate hardness of mono or multicoat paints. A beveled disc with a sharp edge is applied onto the test surface under a constant 500g.  Test load provided by a steel block holder. The trace left after 30 s. Load is measured with a 20X magnification illuminated microscope. The length of the indentation is inversely proportional to the hardness.

CONFORMS TO : BS EN ISO 2815, ECCA T12

Technical Parameters :

  • ◆ Dead weight of indentation device:1kg±5g.
  • ◆ Indentation load:500±5g.
  • ◆ Accuracy of indentation reading:0.1mm.
