What ppm meter works accurately always having trouble with consistency with different meters

Hanna, Apera & Blue Labs are all highly regarded.

What kind of meters do you have? Have you tried calibrating them??

I have a blue lab and it doesn't calibrate accurately for some reason I bought a few different ones from Amazon and different readings for each one i forgot about ppm solution. I'll order some and see what happens thanks
