Surface Tension Test Pens (Dyne Test Pens)

Surface Tension Test Pens were introduced to give an accurate measurement of graduated surface tension levels. The fluid is applied to

Rub Resistance Tester

The BGD 630 Rub Resistance Tester measures abrasion resistance in printing, PS boards, and coatings. It identifies issues like ink detachment and poor layer durability, ensuring improved product quality.

  • Wide voltage design (110–220V, 50/60Hz)
  • Variable speed (5–95 c.p.m, stepless control) with LCD display
  • Permanent parameter storage for consistent testing

Precise Rub Resistance Tester

Precise Rub Resistance Tester (BGD 632) is designed for testing the abrasion resistance of printed materials like labels, cartons, and packaging. Built to ASTM D5264 and TAPPI T830 standards, it ensures durability, reduces quality issues, and supports efficient production control.
  • Tests dry/wet rubbing, scuffing, smear & transfer.
  • Dual testing stations with multiple speed options.
  • Microcomputer control with LCD display & auto memory.

Digital Emulsification Tester

The Digital Emulsification Tester evaluates the water demand of hectograph ink and binders using planetary stirring for uniform dispersion. Compact and reliable, it is ideal for ink manufacturers and quality labs.

  • Planetary double-frame stirrer for efficient emulsification.
  • Adjustable speeds (90/100/150 r.p.m.) with programmable control.
  • Compact 20 kg design with real-time parameter display.

Automatic Drying Tester for ink

The Automatic Drying Tester for Ink measures ink drying time by using a rotating cylinder and a 100 g weight wheel that marks wet areas on parchment. With a touch screen and programmable duration (5–20 hours), it ensures precise and consistent results.

  • Rotating cylinder with linear weight wheel movement.
  • Adjustable test duration (5–20 hours) via touch screen.
  • Accurate drying analysis through ink trace detection.
