Foaming Characteristics of Lubricating Oils.
This test method covers the determination of the foaming characteristics of lubricating oils at 24°C and 93.5°C. Means of empirically rating the foaming tendency and the stability of the foam are described.
Foaming Bath (4 places) - ASTM D892
Compact structure painted with anti-acid epoxidy products with 2 double standby support for rubbers and air diffuser glass tubes.
2 independent bath insulated and equipped with 2 wide double windows equipped with illuminating LED barriers.
2 drain tap.
Air coil placed into the bath at 24°C with the output placed on the left side for the air volume control.
Cover with 4 holes for the accommodation of up to 4 foaming test cylinders.
On the front the 4 flowmeter with regulating knob grant the easy adjustment of the air flow as foreseen by the method.
On the base 2 digital thermoregulator with PID (one for 24°C and one for more than 93.5°C) with over-temperature alarm and probe PT100A.
Heating supplied by stainless steel heater.
Main switch , 2 safety thermostat for overheating, 4 button to activate the 4 built in low voltage micro pump.
Four graduated cylinders.
4 diffuser stones (not certified).
4 rubber stoppers, 4 air diffuser tubes.
