Handling Instructions – H-B Ins
Cleanliness and Handling
Cleanliness increases the measuring accuracy. For uniform and reproducible readings, the hydrometer
must be free of fingerprints, from handling the body, and free of test liquids or materials. The jar must
be clean and free of all impurities. Clean hydrometers and measuring cylinders with de-ionized or
distilled water and dry them with a lint-free cloth.
Attention
After cleaning, you can only touch the measuring instrument at the stack point above the scale reading.
Hold the hydrometer carefully between thumb and forefinger, at the top of the stem only, when
immersing in the jar for testing.
Handling and Packing Hydrometers
Hydrometers are extremely delicate instruments. We recommend placing the instruments back into the
packaging after each measurement or place frequently used instruments in a rack. We pack delicate
hydrometers individually to avoid breakage. When packing or handling, before and after use, hold the
hydrometer by the body to protect the instrument, shielding the stem from shock or impact.
