Salinity gadget (Mid March)



Sweet! I like trying out new things and this is pretty cool. Here's the blurb about the refractometer.

In use, a sample is sandwiched between a measuring prism and a daylight plate. The reading is taken when a shadow line crosses the scale from the shadow line formed between the illuminated area and the dark area then a shadow line crosses the scale. Because refractive index is very temperature dependent, the ZGRS-10ATC Handheld Refractometer embedded a bi-metallic strip inside the rugged casing to achieve automatic temperature compensation.
