FAQs

How often should I calibrate the refractometer?

Calibrate the refractometer before the first use and periodically thereafter, especially if readings seem off.

What kind of water should I use to clean the refractometer?

Use distilled water to clean the prism and the refractometer body.

Why is my reading different from a previous reading?

Make sure your refractometer is calibrated. Changes in temperature can also influence readings.

Can I use this refractometer for freshwater aquariums?

No, this refractometer is designed specifically for saltwater.

How do I interpret the readings?

Read the scale to determine the specific gravity (SG) or parts per thousand (ppt) of the salinity.

What is the recommended salinity level for my aquarium?

The ideal salinity depends on the specific organisms in your aquarium. Consult guides and expert advice for the best level.

Troubleshooting

Readings are inaccurate.

Recalibrate the refractometer using distilled water. Ensure the prism is clean and free of debris.
