Features: – Tri scale measurement. – Test concentration of the battery fluids, antifreeze liquid and cleaning fluids. – Built-in automatic temperature compensation. – Built-in calibration knob. – Aluminum construction with non-slip rubber.
Features: – This dual scale salinity refractometer is used to measure, monitor and control the concentration of salt water and brine, especially useful for aquarium and marine applications. – This high refractometer measures on 2 scales, specific gravity (D 20/20) and parts per thousand and difficult to read hydrometer. – With just a couple of drops of aquarium water you know exactly what your salinity is. – This refractometer does not need calibration solutions like some other refractometer. – Simply use everyday drinking water to calibrate in 30 seconds upon first receiving or after a long dormant period. – A refractometer is easier and more accurate than a hydrometer for measuring sugars. – Made of sturdy aluminum.
