Buchholz Coating Hardness Tester BH-2815
Buchholz Coating Hardness Tester BH-2815 is used for hardness measurements of coating’s using the indentation method (bevelled disc of stainless steel block with constant test load of 500g.).
Buchholz Coating Hardness Tester BH-2815 is standardized to comply to: ISO 2815, BS 3900-E9, DIN 53153, NF T30-052.
 
The device is to be places on the coating for 30 seconds and the length of any subsequent indentation in the coating is to be measured using the graduated microscope. Using the conversion scale, user can get the result in Buchholz Indentation resistance units.
