The cooling cover adds water cooling to a PR-43 refractometer when the refractometer
temperature threatens to rise too high for its electrical components. A cooling cover
is needed when the ambient temperature is over 45°C (113°F) or the refractometer
internal temperature alarm has been triggered, which happens when the internal temperature rises over 65°C (149°F). It is recommended to use cooling cover when internal
temperature rises above 60°C (140°F). The cooling cover is installed between the cover
plate and the sensor cover.
