Made from optical quality polycarbonate plastic material, these plain form hydrometers are durable and shatterproof, and perfect for field work where breakage could be a concern.

• Polycarbonate plastic construction
• Durable and shatterproof
• Easy-to-read black scale on yellow back
• Individually serialized

They are used for measuring sodium chloride saturation of salt brines in various industries including food, fishing, and transportation

Note: Polycarbonate hydrometers are not recommended for use with petroleum-based liquids or other corrosives that would potentially affect the plastic material. They should be stored in a clean, dry, safe place and should not be subjected to extreme temperatures.

At 300 mm (12”) long, they contain lead free ballast and are available in models to measure various levels of salt content from 0% to 100%. Easy-to-read black scale on yellow back helps avoid eye fatigue. Each is individually serialized and has a temperature standardization of 60°F (15°C).
