The one from Blue labs is a good one although a bit pricy.
Runs about $ 230 can 
On Amazon.

The cheapy 2 and 3 probe ones are notorious for not being accurate.

Been using soil this ph pens since 2019.
These are accurate to within ± .2 and I have 3 of them as they eventually do need to be replaced with use. Soil use only no liquids. Also shows moisture content and has a nice long probe to test shallow and deep into pots.
I recently got this one and did work at first but after a couple weeks failed to calibrate so I returned and got a replacement unit and so far is fine for both liquid and soil measurements.
I also found this one that comes with a second probe if original probe is damaged or stops working.
The first one is fairly accurate and with the new digital model I was able to confirm which of my three were still fairly accurate.
I looked into the blue lab and emailed them about replacement probes and there reply said throw it away when it fails as there is no replacement probe so for that kind of money I was out for that one.
Hope this helps.

Pulse also has some probes that stay in the medium I believe. Pretty expensive though.

Wow over $300 and doesn’t do PH
Does moisture, EC and soil temp.
The digital ones I posted above does do soil temps or liquid temps.
I’ve used an old meat thermometer for the soil temps lol
Interesting product though

lol. Didn’t notice there was no pH option. Yeah the price is insane. I’d imagine it would be beneficial in hydro application, like 1 per zone. Idk.
