Abstract
A device for taking liquid samples from a liquid circuit has a needle head ousing formed of an outer component and an inner component readily detachable from the outer component for easy replacement. The outer component includes inlet and outlet ports to be inserted in the liquid circuit. The inner component includes a flow passage aligned with the inlet and outlet ports of the outer component, a pressure reducing arrangement for generating a pressure drop of the liquid flowing through the passage and two hollow needles supported in the inner component and projecting outwardly therefrom. The needles have first ends that communicate with the passage in the inner component at locations where different liquid pressures prevail and second ends which are insertable into a sampling vessel.
