Hydrometers for Zinc Sulphate Testing in Sheep Footbaths
Zinc sulphate testers are used by sheep farmers to check the concentration level of zinc sulphate in sheep foot baths.
The product consists of a small glass tube with an enclosed weight to keep it standing upright in a container holding a sample of the footbath solution. The tube is marked by level indicators. The higher the concentrationof zinc sulphate the more buoyancy is created so the tube floats higher up for the higher concentrations and sinks lower down for low concentrations. The farmer just needs to read off the height level against the surface of the water to determine the remaining concentration of zinc sulphate.
