It looks like a good one to me...A really nice thing about that meter is having the cord so you don't have to dip the whole item in there...the one I got claims to be waterproof but I don't like getting anything with batteries submerged if I can help it

I was debating between the Milwaukee yer lookin at and a hanna pen tester...I ended up goin with the hanna 98129 for several reasons

1. It was a bit cheaper I think you can find it online with all the test calibration/storage supplies for like 120 including shipping

2. The ph sensor or whatever is easily replaced not all that pricey it's like 50 bucks so if it does go it's atleast some savings

3. It was a bit more accurate than that model...I wasn't super pleased with having a .2 variance on ph...this one claims a .05(to answer your 1 point/2 point question I believe the 2 point test helps with accuracy) and it has auto adjust for the temp

4. It was in stock at the local shop so I could walk out with it in hand and bring it back if somethin was wrong with it...

I haven't used it yet cause I just got it this afternoon but I'll post back tomorrow with how well it functions

I bet the milwaukee will last longer than the pen though which is a big consideration...

Honestly any tester whether Milwaukee or hanna will give you more than enough accuracy to have a successful grow so good luck and happy cultivating...let us know how it turns out
