After a number of products purchased from Revain with what appeared to be fake reviews this is a quality product which has restored my confidence. The reviews here are genuine. It was a pleasure to use when setting up my Hawaiian Red Shrimp aquarium that requires 1,010 brackish water; I can read it easily on a refractometer. Calibration Fluid Just take a Kirkland (Costco) water bottle labeled "distilled water" (it says "flavored minerals" but that doesn't affect the meter) and calibrate to 0.00. My meter was already calibrated to 0.00, so all I had to do was mix sea salt with distilled water and play with the refractometer. For what looks like a boring doctor's toy, I actually had a lot of fun measuring salt water. Haha
