Advancements in Foam Porosity Measurement

The first version of IDM Instruments’ Foam Porosity Tester F0016 was designed and released in the 1980s, in accordance with global industry standards, and was used to determine the ease with which air passed through a cellular structure, namely foam, by comparing the relationship between pressure and flow when subjected to different foam samples. It used vacuum chambers with manometers and was controllable via a manual dial to fine tune flow. This version was purely analogue and required fine use of the dial and flow tubes to be able to give accurate test results. Due to the purely analog design, it was difficult to achieve accurate yet repeatable test results.

After more design and upgrades, the second version Foam Porosity Tester F0023 was released in late 2001. Once again improving the accuracy of foam porosity testing. This model boasted variable flow ranges, allowing for more ranges of conditions of testing foam porosities. A huge feature of this model was the addition of an optional printer that allowed for data recording and printout, further increasing reliability and repeatability of tests. This model was truly the jump to digital, using differential pressure transducers instead of manometers, and digital flow sensors instead of analog meters. 

IDM Instruments’ constant search for increased quality and consistency through quality control and improvement has perfected our designs, leading to our current version in 2013’s Foam Porosity Tester F0031. Introducing a bright and easy-to-see touchscreen, a 30% smaller footprint compared to previous versions, much faster automatic results, digital manometer with a 0-500 Pa ± 1% range, variable pressure ranges, different flow range options (0.2-20L/min, 2-200L/min, 5-500L/min), automatic pressure control and RS232 data output. Not only does this  version handle regular foams and flexible cellular polyutherane, but also Visco foams (memory foam). Once the pressure has been digitally set on the display, and once the foam porosity tester reaches the set pressure, the rate of airflow is automatically locked in and held on the flow display, automatically completing the test in seconds. Never has it been so easy to test the porosity of foam.

Cobb Moisture Testing with IDM

Cobb Moisture Absorption Test Ring & Roller

This method for measuring water absorption of sized papers is used all over the world. A dry test piece of suitable paper is placed under the cylinder. The 100ml of water is poured over the test piece.

After a specified time the water is poured off and the test piece is placed on standardized blotting paper. Another blotting paper is placed on top of the test piece and the excess water is removed by means of the roller.

The test piece is then weighed again and the results are calculated and reported as absorption in grams per m2, according to the standard method.

ESM750S gets a Big Brother

The recently introduced ESM750S 750 lbF / 3.4 kN tension / compression test stand is a proud Big Brother. Welcome Model ESM750, an extended length version test stand with the same height and travel specifications as the ESM1500.

This test stand provides a niche solution for lower force, higher travel & higher clearance applications.
ESM1500 and ESM750 single-column force testers are highly configurable solutions for tension and compression measurement applications, with capacities of 1,500 lbF (6.7 kN) and 750 lbF (3.4 kN), respectively. With generous travel and clearance, they are suitable for break testing, cycling, limit testing to a load or distance, loadholding, elongation testing, tensile testing, compression testing, and more.
Satisfy various test methods through an intuitive menu with selectable test parameters, such as speed, number of cycles, etc. Up to 50 profiles may be saved and password protected. Crosshead positioning for sample setup is a breeze with available FollowMe®. Using your hand as your guide, push and pull on the load to move the crosshead at a dynamically variable speed.
The stands feature a unique modular controller function platform. Functions such as travel measurement, cycling, etc. are offered individually, accommodating a wide range of budgets and applications.
Collect force and travel data, plot and analyze results, and control test stand motion via MESUR®gauge Plus software. Or, fully control the stand by a PC through a custom application.


  Applications include:
  Cardboard • Foam • Paper • Plastic • Rubber

Model: C0043
This device is intended for preparation of circular / square / rectangle test pieces 
with uniform edges. It is pneumatic, for easy operation, and repetitious sample cutting.
