A detection head equipped with a conical wiper seal is immersed in the liquid to be measured, and the amount of light from the light source that reaches the light receiver via the liquid to be measured is drawn into the measuring tube by the wiper seal is measured. A densitometer for detecting the concentration of a measuring liquid is characterized in that a recess having an appropriate depth of □ is formed on the tip face of the wiper seal, the outer circumference of which is a concentric circle having a diameter smaller than the outer periphery by an infinitesimal dimension. Densitometer.
