• 

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 Wine and Grape products. 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 
with a 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.

•  To reduce the effects of evaporation or absorption of water when taking 

readings over a period of time, the prism and sample well can be covered 
with plastic wrap.
