Frustrated of your inaccurate swing-arm hydrometer? Throw it away and get the results you have been asking for.
Highly accurate refractometer comes in a convenient foam padded hard case for safe storage. Featuring the same accuracy as more expensive models, this optical device provides a direct reading of specific gravity and salinity in water. Requires no batteries and automatically compensates for temperature (ATC).
- Easy to calibrate
- Adjustable eyepiece
- Large pipette
- Calibration screw
- ATC, compensates automatically to temperature changes
- Hard foam lined case
- Dual scale, 0-100 ppt salinity and 1.000-1.070 specific gravity
- Microfiber cloth included
inTank recommends calibration with 53.0 mS solution. Typical reef aquariums run their salinity constant at a level between 1.024-1.026. Calibrating with pure water is not 100% accurate.
