This 'Brinometer' is an accurate hydrometer that is designed to measure salt solutions and show the exact concentration. It is manufactured from hygienic glass and floats in the brine solution to give an instant, simple and clear reading. The calibrated stem shows the concentration of salt - vital for cheese makers who use brine solutions during the production. It is also useful in the fields of butchery and food technology or wherever the strength of the brine solution is critical. The Brinometer is calibrated to show all brine strengths possible - from pure water to a saturated salt solution.
