SunGrow Measure Salinity of Water with Aquarium Refractometer, Remarkable Accuracy, Includes Calibration Tool, Ensures Overall Health of Plant and Marine Life, Easy and Clear Reading

    Features:

  • ✔ 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 HEALTH— 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.
