It is a testing instrument that simulates the softness of the hand feel. It is mainly used to measure the softness of medium—and high-end toilet paper, fiber fabrics, and other sheet-soft materials.

The KR‑438 bench‑top softness‑measuring instrument objectively quantifies the hand‑feel soft‑hard property of thin sheet‑form materials, simulating human tactile perception under controlled laboratory conditions. It adopts precision probe‑indentation measuring principle to convert subjective hand‑feeling into repeatable numerical test‑readings.
Compliant with GB/T 8942, QB/T 1060, TAPPI T498, ASTM D2923‑01 and JIS L1096 specifications, this unit is widely deployed in paper‑making factories, hygiene‑goods manufacturers, new‑material R&D labs and third‑party inspection bodies for incoming‑material QC, new‑formula comparison and finished‑product release‑verification of tissue paper, napkins, non‑woven fabrics, thin‑films and fibre‑based sheets.
