The refractometer is a precision optical instrument used to determine the salt concentration in saltwater aquaria. Its exact value can be determined in seconds and can be read either as absolute salt concentration (, ppt) or as specific density. When a beam of light enters the refractometer it is bent or “refracted” by the water in the test panel. This refraction is proportional to the salinity of the sample and can be directly read by viewing the internal scale.
Included in shipment: refractometer, a pipette for the water sample, a screw driver for calibration, desalinated water and a strong plastic box.
Option: 60 ml test fluid 35 ppt
Due to new regulations concerning button batteries the Refractometer LED is no longer available.
