- EASY TO USE - Put 2-3 drops of sample on the refracotmter’s prism, towards light, read the accurate readings through the optics eyepiece directly
- DURABLE MATERIAL: The optic salinity tester is made of aluminum and ABS rubber, anti-rust, non-staining and resistant abrasion. Portable Refractometer comes with plastic case, mini screwdriver,a dropper and a cleaning cloth
- Specifically Designed Refractometer For Saltwater Aquarium --- The algorithm is made specifically for testing seawater and saltwater. This is different from a standard refractometer which is not calibrated to check salinity of aquarium water and will give an error in your readings.
- Automatic Temperature Calibration --- The calibration process should be carried out with both the room and the instrument at 68° F. The refractive index of a liquid changes with temperature. Due to the automatic temperature calibration, any changes in ambient temperature from 50° F- 86° F will not affect the accuracy of the reading.
- Easy And Clear Reading For Saltwater Aquariums And Reef Tanks --- The refractometer comes with a focus adjustment on the eyepiece, this will give you clarity of the optics and a sharp line for easy reading.
- Comes In A Solid Case Includes Pipette And Calibration Tool --- This refractometer is not only built extremely well, but it comes with a durable hard case for easy storage of the refractometer when not in use. It also includes a calibration tool and a pipette.
- Keep Your Fish And Plant Life In Optimal Well-being --- Pure saltwater is crucial for the vitality of your marine or reef aquarium. Use this refractometer to measure the salinity of the water, the target level of salinity in a reef tank should be 35 ppt.

FAQ:
Q: What kind of refractometer do you use for fish?
A: When it comes to fishkeeping, there are two types of refractometers that are commonly used: 1. Handheld salinity refractometers (analog) This is the cheapest and most commonly used aquarium refractometer.
Q: How is a Refractometer used to measure the salinity of water?
A: And, it turns out that you can use refraction to determine the salinity of your aquarium. You see, light refracts differently according to the amount of salt that is dissolved in the water. A refractometer can “read” these differences, allowing you to accurately measure the salinity of your tank.
