• Handle instrument carefully. Do not drop.
• Do not immerse instrument under water.
• Do not spray water to any part of instrument except the “sample well” located over the prism.
• The instrument is intended to measure sodium chloride solutions. Do not expose instrument or
prism to solvents that will damage it. This includes most organic solvents and extremely hot
or cold solutions.
• Particulate matter in a sample may scratch the prism. Absorb sample on soft tissue and rinse
sample well with deionized or distilled water between samples.
• Use plastic pipettes to transfer all solutions. Do not use metallic tools such as needles, spoons
or tweezers as these will scratch the prism.
• Cover sample well with hand if measuring in direct sun.
