This is a very nice kit with excellent calibration instructions

It's a quality instrument with all the functions I need and good instructions

The instructions to calibrate don’t seem that difficult to follow but it is a lengthy process

Comes with a case and very good instructions with photos

This meter is great, it's got clear instructions, allows you to calibrate to +

Mainly because it appears to be a higher quality, well made device - even though the included instructions and funky calibration procedure hold it back from a five star rating

absolute trash product, instructions and display

The instructions were total crap--sketchy, and written by someone with only the vaguest acquaintance with English.

The instructions are clear and the calibration process was a breeze.

The instructions were clear and easy to follow

That said it works, it’s easy to read and it comes with clear concise instructions

I think that the manufacturer doesn't give detailed enough instructions on proper probe maintenance and storage

It comes with nice looking printed instructions, but they are confusing, and sometimes contradictory

The Apera PH20 comes with excellent instructions, calibration solution, batteries, and a lanyard all nestled safe and secure in foam inside a hard-shell carrying case.

I had to try a couple of times to get it calibrated, but the instructions made it easy enough to figure out what I was doing wrong.

In the box, there are two vials of buffer solution for calibration (4.0 pH and 7.0 pH), all four requisite batteries, a nice little two-sided laminated graphical instruction quickstart manual explaining what to do with the aforementioned items, a certificate of quality, a lanyard, a full instruction page, and the device itself

And I love the laminnated instructions within the package.

Easy to use, good instructions.

The instructions are clear and come on a laminated card.1

-missing cap-missing BOTH calibration solutions-includes incorrect instructions for pH pen, not for the EC pen which I purchased

The instructions are so bad, I don't even know where to begin.

This instrument came in a very nice case with excellent instructions.

They provide plenty of calibration buffer solution, and it comes in a nice case with good instructions.

The instructions are just confusing as ever

Had great instructions and online tutorials to get started

For storage the instructions recommend a special solution but they also state you can use the included pH 4.0 solution temporarily

Practically right out of the box it works, just follow the instructions and calibrate the item and it will work fine, as long as you fill the cap with a bit of electrode storage solution (or the 4.0ph calibration solution in a pinch)It uses 4 AAA batteries and if you're like me, you have a ton of the rechargeable laying around

Comes with clear and precise instructions and works as advertised.

Easy instructions.

Easy to use, very well made, excellent operating instructions (including an illustrated laminated card.

The instructions are very easy to understand, had absolutely no problem with the calibrating procedure of the tester and find the tester extremely easy to use

ok, so the instructions are SUPER confusing

The instructions on use, storage and calibration are excellent

n’t believe how fast it lost sensitivity

n’t believe how fast it lost sensitivity

This meter has a nice cap with an O-ring that does not leak, so I expected it to last a while
