Dispatched within 5 days
Brought to you by TMI Büchel, our world-leading physical properties testing brand, this digital bench micrometer for paper measures and stores multiple thickness readings, providing a cross-machine profile. Designed for the Paper and Pulp industry, the 49-85 helps manufacturers and quality control laboratories monitor thickness variation and maintain consistent material specifications throughout production.
Like all of our digital micrometers, the 49-85 Digital Micrometer uses the deadweight principle for accuracy and repeatability.
Digital micrometers enable you to accurately measure the thickness of a range of materials. A digital micrometer caliper can be controlled through a computer terminal, or remotely. Some digital micrometers are used together with other testing equipment. Plus they can be relied upon for continuous or single testing and statistical analysis.
The Digital Micrometer 49-85 is designed specifically with the paper industry in mind. It was constructed to meet the single-sheet thickness and variation requirements of TAPPI T 411, the international specification and test standard for paper and board. This supports repeatable caliper measurement across the sheet, helping paper manufacturers and laboratories quantify thickness variation, verify conformance to specification and identify process drift before it affects finished material quality.
As you’ll read below, we also make digital micrometers for all types of material testing from corrugated, paper board, and tissue paper through to plastic film, nonwovens and textiles.
The 49-85 digital micrometer is protected with a heavy, solid frame. This houses the reflective linear encoder and associated circuitry for long-lasting use.
Strengthening the device further, we also constructed the lower anvil and movable pressure foot from lapped, solid stainless steel. Our digital micrometers truly are built to last!
Using the 49-85 digital micrometer you can store up to 100 readings. Each set of tests can be analyzed for high, low, average, and standard deviation. This allows paper production and quality teams to quantify caliper variation across a test series, compare results against target tolerances and identify shifts in material consistency that may indicate process or converting issues.
With a precision digital linear encoder measuring system and an ultra-clear, easy-to-read display, our electronic micrometers are so simple to use. You can inspect each thickness measurement in real time on the digital readout.
Our 49-85 micrometer is compatible with our advanced GraphMaster software, where you can easily save your data and print out if you require a hard copy. For auto-programming cycles, the GraphMaster software is a necessary addition to get the most of your 49-85 micrometer’s capabilities. This gives quality teams a clear record of thickness data for traceability, trend analysis and comparison against specification limits, helping identify material or process variation over time.
Over the decades we have designed and built many digital micrometers and accessories. Why not check out the Digital Micrometer 49-86 which is made for the thinnest of samples? Or the Digital Micrometer 49-87, as well as our Digital Micrometer 49-56, which can be configured to meet a variety of international specifications for many different types of materials.

Poor calibration services → Selected Industrial Physics as a service partner → Superior service achieved! ✓
Proper calibration of your inspection devices is essential for a long and accurate life of service. A leading pet food manufacturer discovered this when shoddy servicing created a raft of problems with their burst and creep testing equipment.
Our experts quickly identified and rectified the pre-existing problems. Now, they’re delighted to rely upon a trusted test and inspection partner with Industrial Physics.
Scott Chambers, Quality Technician at Mars Inc., said,
“I was very happy to be one of the first companies to participate in the mobile calibration program. Ryan Moreno was my technician and was very personable, knowledgeable, and accommodating. The calibrations he performed were very efficient. I like having a technician on site one on one to answer any question I had. Also, not having to ship my BT-Integra units was a major plus. looking forward to future visits at Mars Petcare KKC.”
