I have the Hanna, works great. ATC and waterproof.
You'll need the buffer solution as well to calibrate it every once in a while.
There is also a storage solution, but I can't remember if it comes with it or not.
I recommend checking out this guide.
I like the Hanna HI98128. It's water proof, floats, and has ATC as well as a hold function. If you don't need .01 accuracy, you can go down to the HI98127 for about $15 less. I personally have the HI98128 and it has worked very well for me. The electrode on the Hanna's are replaceable as well and run about $40.
Does he have a pH meter? If not, I would highly recommend one. I would choose Hanna Instruments.
Edit: I have this one, but they do make cheaper ones.

I've never used either of those. This is the one I have, Got it based on the recommendation of a few pros I know

I am a chemist but my old man isn't. I bought this meter and pre-mixed buffer sol'n for him:https://www.amazon.com/Hanna-Instruments-HI98128-Temperature-Tester/dp/B0085WV6GM
I helped him calibrate it over the phone and it's been working well for him, I'll test his beers on my expensive bench top meter and the meters always match +/- 0.03, which is definitely close enough for brewing. The meter has a replaceable electrode and a decent warranty, and it holds a decent calibration when stored for weeks, obviously works best when calibrated every use. Only complaint is the little cap to store it submerged in solution could be better designed.
I just looked into buying one last year. There's not much under 40 that gives two decimal digits with good accuracy. I ended up inheriting this one that is $97. I'm not convinced that 2 digits is necessary for brewing, but I'm very happy with the Hanna.
If you're just getting into water chemistry and are looking to save money, I'd go with something like this. Good luck!
I would invest in a decent portable pH meter
A good set of Hydrometers, maybe even an Ebulliometer if you can find a reasonable one.
Also, a rig/stirrer/flask and reagents for testing sulfur additions accurately is insanely helpful.
Temperature control is nice, maybe a jacketed 50 gallon tank of some sort?
