Micrometers

A bench micrometer is a fixed-position precision instrument used to measure the thickness of a material under a defined contact force. Industrial Physics supplies bench micrometer models from TMI Büchel – a precision instrument brand used in QC laboratories and R&D facilities across the paper, film, plastics, nonwovens and coatings industries. All models are designed to support testing to recognised ISO and ASTM standards, including ISO 534, ISO 3034, ISO 4593, ASTM D374 and ASTM D6988.
 
Micrometers measure the precise thickness of a material under a defined contact force. Used across incoming goods inspection, in-process QC, and R&D material characterisation, they are suited to papers, boards, films, plastics, nonwovens, and coated substrates.
 
Industrial Physics offers bench micrometer models from TMI Büchel, covering a range of foot geometries, contact forces, and measuring depths to match your specific material type and applicable standard.
 

Who uses micrometers – and for what?

 
Industries: 

• Paper and pulp – thickness testing of paper, board and corrugated packaging to ISO 534 and ISO 3034
• Films and flexible packaging – film and laminate caliper measurement to ISO 4593 and ASTM D374
• Nonwovens and technical textiles – thickness of nonwoven substrates and woven materials
• Coatings and industrials – substrate and insulation material thickness to ASTM D374 and ASTM D6988
• Plastics and rubber – sheet and film thickness across a broad range of material types

 
Applications: 

• Incoming goods inspection – verify material thickness against specification on delivery
• In-process quality control – monitor thickness consistency during production
• R&D and material development – characterise and benchmark new materials and substrates
• Compliance testing – confirm materials meet ISO, ASTM or customer-defined thickness requirements
• Final product QC – verify finished goods before dispatch or customer sign-off

Why Industrial Physics for Thickness Measurement

Instruments built around test standards: 

TMI Buchel bench micrometers are designed to comply with ISO and ASTM test methods from the ground up. You get an instrument built for the standard your process requires, not one adapted to it after the fact.

Applications expertise: 

Our applications team can help you select the right micrometer based on your material type, required measuring range, foot geometry, contact force and applicable standard. If the answer is not on this page, we can find it.

A complete testing portfolio: 

With 12 brands and more than 3,000 products across 19 industries, Industrial Physics can advise on your wider testing requirements beyond thickness alone – from tensile and barrier testing to printability and surface analysis.

Global support: 

Operating in 75 countries, Industrial Physics provides local sales and service support across major markets. Instruments can be calibrated, serviced and supported wherever your operations are based.
