this is a cool thread. im noticing alot of people like the blue lab pen although for the price i would rather buy the meter with seperate probe so if the probe dies i can just replace that.
ive used a blue lab truncheon and will never switch as its a fantastic tool. ive not had a blue lab ph meter yet but i shall be buying one next i think.

I really do like my blue lab meter that I got as a replacement for my Hanna. I thought I was getting a pen-style meter but I don't think they have one that is a combo.

Another bluelab devotee here. My Ph pen holds calibration way better than the Hanna it replaced. In fact, the Hanna had too be calibrated every use. I also love my truncheon.

LOL. even when my Hannah was calibrated properly and would read the test solutions correctly it would always read the pH of my tap water as 7.1 even though it was 7.4

blulab has a ph/ec-ppm combo meter
a Ph pen and several ec/ppm pens and truncheons.

BL is the bomb!
I love my combo meter but the ec/ppm part went out.
Ive had it for 3 years and got it for $50 from the auction house.
and it was 4 yrs old at that time!
so i picked up the ppm pen and love it
and the ppm pen also has an ec setting on it

picked up an HM Digital pH pen model 200 and there Com200 ec/ppm/ppt. Both are solid pieces of tech. better alternatives from hana and oakton.
