Flash-point tester has compact design

Edited by the Laboratorytalk editorial team May 8, 2006

TAG 4 is a fully automatic closed cup flash-point tester which, in its standard version, covers a measuring range of 0 to 110C

The TAG Method covers the determination of the flash-point of liquids with a viscosity below 5.5mm2/s (cSt) at +40C (104F), or below 9.5mm2/s (cSt) at +25C (77F), and a flash-point below +93C (200F).

To ensure an acceptable precision, this dynamic flashpoint test method employs a prescribed rate of temperature rise for the material under test.

The flashpoint measures the tendency of the specimen to form a flammable mixture with air under controlled laboratory conditions.

It is only one of a number of properties that shall be considered in assessing the overall flammability hazard of a material.

This method can indicate the possible presence of highly volatile and flammable materials in a relatively nonvolatile or nonflammable material.

For example, an abnormally low flash-point on a sample of kerosene can indicate gasoline contamination.

TAG 4 is a fully automatic closed cup flash-point tester which, in its standard version, covers a measuring range of 0 to 110C.

A low temperature version is available for lower flash-points, extending the operating span down to approx -35C.

The instrument uses solid state cooling elements.

This avoids any external cooling and untidy tubing.

The result is a compact design with a footprint of 23 x 40cm - a serious consideration when the TAG 4 is placed in a fume hood.

Only the low temperature option needs a small cooling circulator.

The TAG 4 is easy to operate: move the patented multi-function-head with one hand into its operating position and all connections are instantly made ie assembly of igniter, temperature- and flash-point indicator.

A touch key panel and a 2 line LC-display allow easy setting of the estimated flash-point, selection of the test program, indicates whether the flashpoint is valid and shows error messages (eg igniter failure).

The TAG 4 finds applications in the manufacture of Fuel, Gasoline, Jet Fuel, Kerosene, Mastics, Paint, Regulatory Authorities, Solvent, Turbine Fuel, Varnish.
