Toluene, also called methylbenzene or phenylmethane is an aromatic hydrocarbon.

It is commonly used as a reagent or solvent, especially in the industrial environment. It dissolves a large number of oils, greases, or resins (natural or synthetic). Under normal conditions, it is a transparent liquid with a characteristic odor, reminiscent of paint remover or related benzene.

Thanks to its PTFE cable and its PVDF casing, the TUBA 125C can be used to regulate / detect the level of toluene in a tank.
