That's what I thought at first the hanna had the same reading range n all but a fraction of the price but bluelab she settles on ph fast n auto cal is a life saver
How often do you calibrate and actually see a difference in readings? I have a 50€ pH pen that I calibrated once after a year of use and it was 0.1 off

Only calibration I did was at the start since then my tap water is 7ph so once it reads that I know it's not off I also get a tick when the ph is stable

I calibrate mine weekly just to be certain but I do NFT so it has to be right. I've had that for over three years and it's still got the original batteries in itView attachment 3823302
I had one like that

pop`d the glass bit checking it before calibrating one time

Yeah they do drift takes around a month before I normally have to calibrate, had mine for 2 or 3 years too, go an essentials one now just as good, probably loses a bit less but its newer so who can really say.

You use an EC or PPM or TDS meter too ?

i calibrate every week takes 30 seconds. And i always calibrate if i get a reading i feel is strange.
I calibrated when taking reading of my tap as the numbers were weird (7.5 instead of 7.2). Turns out the water was off but also the pen (0.1). I usually stick it in distilled water to check the accuracy instead of using both solutions. Although I use my pen only 3-4 times a year.

Don't calibrate anything with distilled water it is completely unbuffered and will soak up CO2 instantly making it acidic, basic level stuff don't be posting that non sense on this thread

When and where did I write that I use distilled water to calibrate anything?

In the post above (check accuracy), some boring shit tbh this is not the thread for ph pens and how to calibrate them
