Shoof Foot Bath Zinc Sulphate Hydrometer

Used by farmers to check the concentration level of zinc sulphate in sheep foot baths. Use this to keep solution as close as possible to the recommended 10% concentration level for maximum effectiveness of foot treatment and reduce excess costs of wastage. The hydrometer consists of a small glass tube with an enclosed weight to keep it standing upright in solution. Easily and instantly read to measure the level of concentration of zinc sulphate in the liquid. The higher the concentration of zinc sulphate the more buoyancy is created so the tube floats higher up for the higher concentrations and sinks lower down for low concentrations. If the concentration of Zinc Sulphate in the foot bath drops to below 10%, the foot bath mixture is too dilute, and will no longer work as well as it should to achieve the aims of the intended foot treatment. If the concentration is too high, the farmer is wasting money, and also raises the risk of burning the sheep's feet. Hydrometer will measure from 0-20%. Instructions included.
