I do use a hanna ppm pen,it was about 25$ its been good to me too,i calibrate/check it once per month too,its usually just a little bit off but not bad
I use both meters at least 3-4 times per week..the storage solution is cheap insurance,and they are a breeze to recalibrate..we interviewed blue lab and they had started selling rhe kit with the three solutions in it,when i bought mine they werent included

When i switched to coco i bought a Blue Lab ph pen/meter..best 85$ i ever spent.i do check/calibrate it once per month and use the storage solution,but it is a good investment
Thanks for that bro! That's the one I was looking at, I just read a bunch of neg. Reviews saying they had to keep replacing diodes, I saw the oakton one looked about the same quality
