FIELD: chemistry.
SUBSTANCE: invention relates to apparatus for controlling quality of engine fuel. The chemical sensor is a plate made from aluminium foil, coated with a composite sorbent and an indicator. The composite sorbent used is a mixture which consists of silica gel 60, gypsum and liquid glass, and the indicator is a mixture of potassium ferrocyanide K3[Fe(CN)6] and iron sulphate FeSO4, which is blue in the presence of water due to formation of a coordination compound.
EFFECT: more reliable control.
