Impulse is a two-chamber instrument designed and built to meet American standard ASTM D3512, SANS 6116, the Japanese JIS L1076 standard, French NFG07-121 plus more recent ISO Standard 12945-3, when used with the appropriate liner and impeller.

Stylish design and enhanced air circulation

According to James Heal, the Impulse^3 is stylishly designed with two vertically oriented test chambers to occupy the least possible bench space and has significantly enhanced air to keep the specimens tumbling during the test, offering an important advantage over other instruments of this type.

The specimens are agitated within the two chambers by a high-speed (1200 rpm) impeller, and long-life LED technology illuminates the two chambers with clear Perspex allowing the user to view the sample during testing.

This constant calibrated speed of 1200 rpm is guaranteed irrespective of variations in the electrical supply voltage and is checked during the regular Service and Calibration services from the company’s qualified technicians.

Interchangeable impellers

The impellers, which can be changed as required, is said to enable tests to be carried out in accordance with ISO, ASTM and Japanese standards.

The new ISO 12945-3 is based on the French standard NF G 07-121: 1987 and has been adopted by CEN as EN ISO 12945-3.

Unicontroller

The controls are totally intuitive for which no training is necessary, the company reports. Pilling tests can be carried out simply and quickly. The time selection is very easy and the controls also enable the internal light and air to be switched either on or off as required.

There is an adjustable audible alarm to signify the end of the test and a warning will be displayed if the pressure drops below the minimum pressure as specified in the standard.

The UniController has a set time function for the running-in before use of the Neoprene Liners before use as required in the ISO standard and an interlocking door safety switch to assure safe operation.
