Product Description

By entering your model number, you can make sure that this fits.

It's made to measure seawater or saltwater with a low concentration.

Salinity is measured on a scale of 0-100 with a specific gravity of 1. 000-1.

The automatic temperature compensation feature reduces the impact of temperature on the test results.

It's Simple to Use: Even new users will find it simple to use. Furthermore, there is no requirement for a battery.

Ideal for use in a marine fishkeeping aquarium, a saltwater pool, marine monitoring, a laboratory, agriculture, gardening, and education.

Questions & Answers

Is this refractometer really calibrated for aquarium saltwater (sea water) or is it just a regular brine refractometer - Is it NaCl calibrated?

Selected User Reviews For Aichose Salinity Refractometer for Seawater and Marine Fishkeeping Aquarium, Saltwater Pool, with ATC Function, Dual Scale: Salinity 0-100‰ and Corresponding Specific Gravity

Calibration is not retained

3/5

The outcomes are untrustworthy. This loses calibration so quickly that 1) you must calibrate it with 35ppt calibration solution before every use, and 2) the sample readings you get after calibration are sometimes unreliable. If you're calibrating to 0 ppt with distilled water, you shouldn't trust it at all. I'd only use it if you calibrate to 35ppt with a 35ppt sea water calibration solution right before taking your aquarium test. br>br>I did two tests with the same 35ppt calibration solution - Between tests, clean the equipment with distilled water. and the second test was already drifting 1 ppt lower than the first, and if you've had it sitting for a few hours or a day, you're probably 3 or 4 ppt off from the previous calibration. br>br>I'm guessing it's a good tool if all you want to do is compare your tank water to your water change water, and you'll be testing the tank first, then the water change water, and just seeing if they're the same. But, given how quickly it changes its calibration, I wouldn't put much faith in the actual number reading you get unless you don't mind being off by up to 3 ppt. (Which, in my opinion, is an unacceptably large deviation).

In comparison to the competition, the readability is excellent

5/5

It's simple to read this refractometer. The contrast between the dark blue and white indicator is far superior to anything else in this price range with an "atc" stamped on it.
