Not the best cheap and not entirely accurate

Let's keep it a secret for growers who grow whatever you grow it's cheap it's not entirely accurate as you want full accuracy you need no need to buy another pen 🖊 The pH balance will go up and down and also stay between two or three different numbers, be prepared, don't say I didn't warn you

Pros
  • The best
Cons
  • Ugly packaging

Read carefully good for testing, measuring and checking

First, I love them. But my problem is not the strong white substance on the ph meter. I'm sure you made sure they worked after they were made and washed them down with distilled water. My problem concerns your instructions for each device. For the price, both work great, but check out how to calibrate a pH meter on YouTube. When done right, it works great. But throw the manual in the trash

Pros
  • Comfortable to use
Cons
  • old

Pain at the beginning with

out of the box, the device needs to be calibrated, which is not easy. First, you need an accurate thermometer to calibrate. Several glasses of pure distilled water must be heated to exactly 77 degrees and thoroughly mixed with the powder supplied. This gives you very little time to calibrate. Also, you only have one try. I've also found that repeated immersion in the same solution after calibration produces different results. After all, it's reasonably accurate compared to pool storage tests…

Pros
  • a nice thing
Cons
  • I don't remember, but there was something
