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. The integrated LED illumination provides good readability even in poor lighting conditions.
Included in shipment: refractometer, a pipette for the water sample, a screw driver for calibration, desalinated water, LED display and a strong plastic box.
Option: 60 ml test fluid 35 ppt

A TDS Meter measures the amount of Total Dissolved Solids (TDS) in a solution.
This measurement is used to determine the purity of the water produced by your RO unit and will give an indication of when your DI resin or membrane life is coming to an end. The inline version measures the TDS of the feed water before the RO Unit and the TDS of the pure water from the unit.
Since dissolved ionized solids like salts and minerals contribute to the conductivity of a solution, a TDS meter measures the conductivity of the solution which is then converted to a TDS reading.
TDS is directly related to quality of water i.e., the lower a TDS figure, the more pure the water. As an example, reverse osmosis purified water will have a TDS between 0 and 10, whereas tap water will vary between 20 and 300.
