Menardi DB-TT is a system designed to make it easy to carry out sampling of gas filtration media from deep-bed filter, Menardi DB. Menardi DB-TT consists of an inner and an outer tube made of PVC, which together are pushed down into the gas filtration media to the desired depth. Twist the inner tube and poke the tubes together to make it easier for media to fall into the opening.

The pressure drop manometer is suitable as a filter guard. It has an adjustable scale graded ± 0-400 Pa for the measurement of up to up to 800 Pa. pressure differentials.
