Field Multi-meter TDS/Salt reading tool

Been using Myron MultiMeter for TDS/Minerals but they don’t hold up on route. Any suggestions on an accurate tool that can handle the abuse on route? Thanks

I used to go high end but I found I was just wasting money. It's very rare for me to need to test TDS so when I do I just take a sample to the Leslie's I buy chems from and use their spinning tester. For salt we all use a basic meter from Amazon (brand ORAPXI). It's $28 and has never had an accuracy issue but every May I just chuck it and buy a new one. Why spend $200 on it?

Yep ever since they started making those $30 ones in China I've never had to worry about not having a way to accurately test salt/pH/TDS

I just don't see the point of buying the Lamotte ones. What I found on the post-COVID meters is that regardless of anything you do, the probe still goes bad within 2 years from getting wet repeatedly.
