bringing science to the edge
however you slice it...
dull edges and needles are a money losing proposition in your business.
here's how you add a little "rise" to your bottom line...

 now you can measure sharpness levels, compare & communicate those levels and then manage the cutting and piercing tools you work with!

For industry and manufacturing its about quality control and operating efficiencies. For medical suppliers, research labs and hospitals its about better patient care and safer procedures. The BESS, 0-2000 grams, is a linear scale that describes, numerically, how much force is required for an edge or a needle to sever or penetrate a standard test media. Less force equals a sharper edge or a sharper point.

When the BESS score for an edge or needle doubles due to operational usage then, so do your problems. Often, needles and edges are at the very front end of many types of processing and industrial machinery. You don't have to be a physicist to calculate what happens to power consumption and equipment maintenance costs once two or three times times the force is required to do the same job.

For every application there is a BESS "sweet spot". The window where operating efficiencies and product quality requirements mesh best. For most, that sweet spot is rarely the sharpest edge but rather the edge or point specifically sharpened to a level that is best suited for the task. For some that number is 120 and for others 720. Edge On Up instrumentation will first help you discover the location and breadth of your window and then, on an on-going basis, used to test, maintain, and refine your assumptions. There is a whole new productivity frontier awaiting you and Edge On Up and BESS have provided you, now, with the tools to conquer it. Join with the many, from axe bits to scalpel blades and meat processors to carpet mills, who have improved their products and their operations dramatically.  Then start talking, recording and comparing sharpness numbers within your company- BESS Numbers!


ID75A...Industrial/Scientific

The ID75A is the ultimate instrument for precision edge testing and acquires edge sharpness information at lightning speed. The ID75A has an amazing edge sharpness testing range. From literally a single gram to thousands.

While it was primarily designed for bench operation this instrument still has easy portability (6 AA Batteries included) in addition to an included AC/DC power source. The ID75A can talk. At least to Windows (7-10) PCs that is or it can operate stand-alone with a fully back-lit display. The RS232/USB (cable included) link can input measurement data directly into any spread sheet or data base application that is capable of supporting Active X controls. The ID75A basic package includes a demonstration Excel spreadsheet
file that is capable of logging and time stamping measurement data and communications drivers that can be installed directly on your PC. The ID75A can be set to communicate Com data either manually, when the reading has stabilized, or continuously.

The ID75A has one gram of resolution and support loads up to 3000 grams. This instrument measures 7.25" x 10.75" and is 3.5" high not including test fixture. The basic package includes both our Aluminum Test Fixture, pre-loaded with test media, and our Clip Base with 25 disposable test media clips. The ID75A is a true industrial quality instrument and comes with a 3 year warranty.


ID75N...Needle Sharpness Tester

A truly remarkable instrument with regard to both accuracy and  versatility! The ID75N is built on the same frame as the ID75A and shares the same dimensions, RS232/USB capabilities and power specifications as the ID75A above. Simple three button operation and can perform tests in either hand-held or with the assistance of a mechanical fixture (customer supplied). The ID75N performs needle tests in three modes.  The ID75N is capable of operating as: 

* a needle sharpness point tester
* a needle insertion force tester
* a material puncture resistance tester.

That's a lot of "punch" in one package!


 In needle sharpness mode (NST) the ID75N uses BESSU-NST certified test pads (0-2000 grams) to measure the sharpness level of needle points. Certified test pads are only .015" thick so only the point of the needle is tested with little regard for needle shaft geometry. Most tests may be conducted very quickly and accurately in a hand-held manner by attaching the test clip directly to the needle. Generally, NST hand-held readings produce needle sharpness results that are only a few grams higher than extremely accurate tests conducted with the aide of a mechanical fixture. Commonly used needles fall in the BESSU-NST measurement range of 25 - 400 and carefully taken hand-held errors range from 3 - 10 grams and are always an overstatement of the actual measurement. Edge On Up does not produce for sale mechanical fixtures. The average time required to conduct a hand-held needle sharpness test in NST mode is less than ten seconds.

The insertion force test (IFT) is designed to measure the amount of force required to penetrate a NST test pad with regard for total needle geometry. IFT tests do not require that the needle or other sharp object tested be electrically conductive or that the test clip be utilized. The IFT test utilizes the IFT Test Fixture which is included with your standard ID75N package.  The IFT Test Fixture is pictured sitting at  the right-rear corner of the instrument in the picture above but would be placed at the center of the sensor plate during an IFT test.

 The IFT fixture top is covered with a semi-permanent adhesive surface. A standard 1.5" diameter  NST test pad is adhered to the adhesive surface before the test is conducted. The IFT Fixture contains a .375" diameter void area in the center of the fixture which allows the test object to be fully inserted to a depth of 1/2 inch. During the IFT test the test needle is forced to penetrate the test pad fully and the maximum force required to do so is locked on the instrument display. IFT tests are for relative and comparative purposes only. IFT test results are not certified by BESSU (BESS Universal). Your own test materials and IFT fixture designs may be substituted by the user as required by the application. IFT force curves may be derived from data communicated to a PC when the ID75N is placed in continuous output Com mode.

Puncture resistance tests (PRT) are a simple matter with the ID75N and, like IFT tests, are not BESSU certified. Any material, and using any puncture tool (conductive for NST), may be used to test the puncture resistance of one material compared to another as long as the total force required to gain a result does not exceed 3000 grams (6.5 lbs). Puncture resistance tests may be conducted in either NST mode or IFT mode.

Non-Conductive needles and Organic Sharp Objects may be NST tested as well with the application of commonly available conductive sprays and coatings i.e. copper, aluminum, nickel. IFT tests do not require that the needle or object be electrically conductive.

Each ID75N includes batteries (6 AA), AC/DC power transformer, IFT Fixture and 6 NST test pads, RS232/USB cable and com software. In NST mode a single test pad may be used for up to 50 measurements and in IFT mode 1, 2, or 3 tests depending on needle shaft diameter.


PT50A...Industrial

There's plenty said about this handy edge sharpness tester on the home page of our site. The PT50A is the perfect adjunct to our beefier and more capable ID75A. This is the instrument designed to live and work on the factory floor. It's battery operated, smaller, lighter weight and the perfect instrument to measure and help maintain cutting edges on an on-going basis. Many of our industrial customers use multiples of these low cost instruments and at multiple locations.

PT50A measurements match perfectly with the ID75A because they both have 1 gram of resolution and both use our Aluminum Test Fixture and/or our disposable clip system. PT50As include a strain sensor system that was designed to stand up to industrial use and are the only PT50 Series instruments warranted for industrial use.
