The Digital Micrometer 49-86 quickly and precisely measures the thickness and caliper of a wide range of sheet materials, including paper, fabric, films, plastic, metal and leather.
Brought to you by TMI Büchel , our physical property materials testing brand, this reliable digital bench micrometers for sheet materials is designed for the thinnest of samples. It has a highly accurate measurement range of: 0-0.050in. (0-1.27mm), making it the perfect digital micrometer for paper. Its ability to measure thin sheet materials makes the 49-86 relevant to applications across the Paper and Pulp, Flexible Packaging, and Plastics and Polymers industries, helping quality teams monitor material thickness and consistency.
A digital micrometer is a precision measurement tool that’s primarily used for thickness testing. Micrometers can be used for continuous or single testing and statistical analysis. Some digital micrometers are controlled remotely through a computer terminal, others are used in conjunction with other testing equipment.
You can save your electronic micrometer data permanently through the optional GraphMaster PC-based software. Or you can print it off and keep a hard copy for further analysis. This gives quality control teams a traceable record of thickness measurements for statistical analysis, batch comparison and verification against defined material tolerances.
Our electronic micrometers combine a precision digital linear encoder measuring system with an ultra-clear, easy-to-read digital display. So you can check a specimen’s thickness in real time.
We’ve encased our digital micrometers in solid, hardwearing frames. The reflective linear encoder and associated circuitry is well protected from accidental damage.
Built to last, we also constructed the lower anvil and movable pressure foot from lapped, stainless steel.
Our digital micrometers will measure and store up to 100 readings. Plus they’ll analyze high, low, average and standard deviation for each series of tests. For manufacturers working with paper, films and other thin sheet materials, this supports statistical assessment of thickness variation across a test series, helping identify out-of-tolerance samples and monitor material consistency between batches.
You can rely on our digital micrometer 49-86 to give you highly accurate results to the most stringent of international standards, including:
Across the IP portfolio we make a wide range of electronic micrometers for all types of samples. Here are some of the options.
The TMI Büchel digital micrometer model 49-87 can be configured to meet a variety of international specifications for different types of materials including corrugated paper, paper board, plastic film, paper, tissue paper, nonwovens, textiles and other sheet like substrates.
The TMI Büchel electronic micrometer caliper model 49-85 is designed to measure the thickness or caliper of paper sheets with precision and ease.

A cutting-edge manufacturer of sustainable flexible packaging films was searching for an oxygen transmission rate analyzer to be used within an R&D environment.
Ultimately, it was the Systech OxySense 8101e OTR that best fit the needs of TIPA – due to the ease of operation, excellent sensitivity and reliability, and a wide sensor range, it was able to tick all the boxes.
Due to the features of the instrument, TIPA can expand the range of the products they’re developing – a hugely beneficial factor.
