Digital Salinity Testers?

[TOM-779]

Hi Everyone

I was looking at some of the available digital saltwater testers online -
and wondered if anyone has had experience with brands/types on Amazon such as

ORAPXI​

UIUZMAR Store​

www.amazon.co.uk/UIUZMAR-Aquarium-Salinity-Swimming-Hydroponic/​

Many thanks

That link isn’t working for me. But I have had the Milwaukee one and the Hanna. I love the Hanna one. It shows changes in real time and don’t have to calibrate for every use like the Milwaukee

The last link does not work. I’m not familiar with those brand names.

Thanks - I was searching on UK Amazon using 'Digital salinity testers'

I am aware of the Hanna range - but was looking for other options

I have one of those Chinese made digital salinity meters which sits in the tank 24/7. It drifts over time which I reset using a reliable way to measure since the meter itself cannot be trusted without periodic recalibration.

I have tried out 3 salinity meters from Hanna and none were reliable (I still have one sitting around). You really want to go with a reliable method such as Tropic Marine Hydrometer or the VeeGee Refractometer.

Go with a refractometer. Never needs a battery and just needs to be calibrated a few times a year at most in my opinion! :)
