The Foam Porosity Tester is used for monitoring the porosity of flexible cellular polyurethane. The machine determines how easy air passes through a cellular structure. Airflow values may be used as an indirect measurement of certain cell structure characteristics. The F0031 model foam porosity tester is made with reference to international standards for measurement of a flexible cellular test piece, 50mm x 50mm x 25mm, it is placed in a vacuum chamber cavity and a specified automatic constant differential air pressure is applied. The F0031’s Pa Pressure can be digitally set on the display and once the FPT reaches the Pa automatically the rate of airflow at the set Pa is locked in and (Held) on the Flow display automatically completing a test in seconds.

There are several different methods used for the evaluation of innersprings and boxsprings, testing for measurements regarding firmness, firmness retention, durability, effect of impact etc. The Cornell Type Tester is used to test the long term capacity of bedding to resist cyclic loading. The machine consists of a double hemispherical ram head on a manually adjustable shaft. A load cell is located on the ram head to measure the force being applied to the mattress. The shaft is connected to an adjustable eccentric which is rotated by an electric motor at up to 160 cycles per minute, variable. The bedding is located below the ram, and the eccentric and shaft position adjusted so that the maximum load of 1025N and the minimum load of 22N is applied when the eccentric is rotated to the lowest and highest positions respectively. A position transducer is located so the position of the ram head can be measured automatically.

Advance Anti-Sip nonslip Ladder Rung Covers are available in two distinct styles, circular and square, which snap fit easily over the rung providing a long lasting, highly visible surface to climb. Ladders can be a means of access that is used less often than walkways or stairs, therefore adding Advance Anti-Sip Surfaces antislip Ladder Rung Covers will not only make the ladder a safe piece of equipment, they will usually last for the useful life of the ladder. Advance Anti-Sip Surfaces superior Class 1 metal backed antislip Ladder Rung Covers will eliminate the problem of slippery ladders and protect employees and visitors in the area from slips and falls.
