The unit is easy to use and set up using scrolling menus on the LCD display. Results can be monitored throughout the analysis period to ensure accurate analysis. With a selectable automatic start function, variations in sample temperature prior to testing can be eliminated, as the unit will begin the analysis period only when the temperature is constant. Such variations would normally cause errors during manometric measurement. An inductive stirring unit is also supplied to provide consant mixing of the sample over the analysis period.
