Nice
I work in a soils lab and this was just what i needed. I like hanna instruments. It's easy to use and has clear instructions. Comes in a little storage case with some storage solution and a small pack of buffer. It's held up so far so good and I've had it for a few months

Great ph pen at a decent price.
I had a simple Hannah ph pen for ten years. Never failed. I accidentally broke it and ordered cheap ph pens from vivosun. They broke every other week after buying around 8 I looked up the brand Hannah I’m surprised it does not pop up when searching on here. You have to type Hanna ph pen. It’s a decent price. I hope it lasts half the time the other Hanna ph pen I got ten years back. It was calibrated already but I decided to calibrate it myself. Easier than than the vivosun ones to do.

Ridiculous amounts of calibration is was NOT
I wasn't looking forward to having to calibrate the Hanna pH meter frequently... and I wondered how much of a pain it was going to be to use it...Turns out, it's pretty pain free. Granted, I'm only using it to verify pH of fresh water planted aquaria. So for more costly systems (e.g. reef tank) you might opt to recalibrate it more often. Also, my fresh water tanks tend to run around 7.0 pH, so higher (or lower) pH testing may not be similar to my experience.That being said, the Hanna pH meter performs very well. I've used it 20 or so times doing daily pH testing. And I've only had to calibrate it once.The way I get around frequent calibration is simply to verify the reading of 7.0 using the included buffer prior to testing my tank water. And after testing, I immediately put it in RO water to "clean it off"... and finally a quick dip in old 7.0 buffer then I put the cap on for storage.It may not be the recommended procedure but I'm satisfied that it's giving me accurate enough results.
