A useful tool to operate hydrometric and limnological instruments
The winch is made of sea-waterproof aluminium and additionally protected against corrosion by an enamel finish. A counting wheel allows to read out the length of wire paid out. Zero setting is possible. The rope can be fixed at any desired depth. A heavy double screw steel clamp allows for easy fixing at the walls of boats, bridges, rails, well pipes, etc. Rope can be ordered separately or reeled on the drum at any length up to 200m.
