Transformer oil, petroleum products and solvent QC still rely on the ring method written into many specifications. This automatic tensiometer pulls a 19.4 mm ring at 0.1–100 mm/min, measuring 1–1000 mN/m with 0.01 mN/m resolution and ±0.1 mN/m accuracy. Huh–Mason and Harkins–Jordan corrections are applied automatically. Samples need 20–50 mL.
