The TQC Grindometers or Fineness of Grind Gauges are precision instruments to determine particle size and fineness of many materials like paints, lacquers, pigments, filler, chocolate etc.. TQC Grindometers are available in three models:
Double grooves with graded slopes graduated in different parameters: Microns, NS (Hegman) and PCU (North)
Single wide groove with parameters: Microns and Hegman.
Single groove with only Microns.
Material of main block ASAB Stavax ESR medical grade stainless tool steel. Sub Zero Vacuum hardened (+1756°C to -70°C), hardness HRC 55 (through hardened*) Surface treatment: polished Overall accuracy: ± 2 µm. Material of scraper ASAB Stavax ESR medical grade stainless tool steel. Sub Zero Vacuum hardened (+1756°C to -70°C), hardness HRC 55, (through hardened*) & tempered. Surface treatment: black chromed. Overall straightness: ± 2 µm. *Through hardening versus Case-hardening or surface hardening.Through-hardening means the metal uniformly is hardened throughout the piece. Case- or surface (face / frame) hardening only hardens the top layer of the metal. Once the top layer is degraded excessive wear and tear will occur on the product limiting its life time and affecting accuracy.
