Used Hydrometers in Guangdong, China

Consider the type of liquid you need to measure, as different hydrometers are calibrated for different substances. Check the measurement range and ensure it suits your specific needs.

Hydrometers are fragile and should be packed securely in protective packaging, such as bubble wrap or foam. Use a sturdy box and mark it as 'Fragile' to ensure careful handling during transit.

Rinse the hydrometer with distilled water after each use to prevent residue buildup. Store it in a protective case to avoid damage. Periodically check for any cracks or damage that could affect accuracy.
