Micrometers are precision instruments designed for accurate measurements of small distances or thicknesses. They come in different types, including digital and manual micrometers. The determination of non-woven material thickness can be achieved using various types of gauges, with micrometers and thickness gauges being particularly useful in this context.

The Textiles and Non-woven textiles Digital Thickness Gauge can be used to determine the material thickness of non-woven fabrics, textiles, felts, geomaterials, paper, floor coverings, leather, foils, etc. The instrument does not meet the DIN, EN and ISO standards. The feeler shape and the pressure are corresponding to DIN EN ISO 5084 standards. This low-cost thickness gauge is suitable for quick comparison measurements.

Universal testing machine is a high-precision, multi-purpose material testing machine that tests the mechanical properties of various metal materials, non-metal materials, composite materials, and polymer materials in the state of tension, compression, bending, shearing, peeling , tearing and other mechanical properties. The machine conform to ISO 7500/1 Class1, ASTM E4, BS 1610 Grade 1, DIN 51221 Class1

PH-702 bulk density tester is designed and developed by our company according to the "National Standard of the People`s Republic of China GB-T6286-1986" molecular sieve bulk density determination method. It is suitable for the bulk density, loose density and tap density determination of granular materials such as granular catalysts and molecular sieves, and powdered materials.
