User questions & answers

Question:	What is the factory margin of error
Answer:	Yes it can. Salinity and temperature. Does a great job of both.
Question:	Is this accurate when mixing salt and setting your salinity for water change. Iv heard can be off a little when hadn't been mixed that long
Answer:	Yes, mine is always off -.002 compared to refractometers. All devices calibrated. Talk to Hanna support and was told it won’t match a refractometer lol. I like it because it’s fast and easy, if I want my water at 1.026, I just make sure the Hanna reads 1.023 I guess others haven’t had this problem but I do, or the others don’t know their salt mix is high

Operation Instructions of Aquatic Refractometer:

1. Calibration: Accurate measurement depends on careful calibration. To calibrate the ATC salinity refractometer accurately, firstly you should make sure the ambient temperature is about 68℉.Recommend you do the calibration in an Air-conditioned room in which the temperature is set on 68℉. You can use distilled water to calibrate. Open the cover plate,place 2-3 drops of distilled water on the prism, then close the cover plate and make sure the water spreads across the prism without air bubbles or dry spots. Wait for about 30 seconds to let the reading to stabilize. Look into the eyepiece and turn the calibration screw with the screw driver until the reading is "0".

2. Clean the prism with soft cloth, and then place 2-3 drops of the liquid sample to be tested on the prism, look into the eyepiece and you can get the reading.

3. Clean the refractometer with soft cloth and put it back into the box.Keep the refractometer dry and clean, which can make the instrument accurate and durable.
