Lost calibration
2 months later and it was giving inaccurate readings. Tried to calibrate and couldn’t.

IT WORKS GREAT & EASY TO READ!
I am using this meter for testing the water I use for my plants. I found the problem, the PH was way off.I haven't tried to calibrate it but it looks pretty easy to accomplish.

As described and pleased!
It came 100% perfectly calibrated and hasn't needed it in over a month thus far. I tested it with Distilled water and was / still is 0.0 Ph.Great product so far.

Consistently Inaccurate
I calibrated this using the provided solutions, tested my nutes mix, cleaned the bulb with DI, and got a pH 0.3 off from my first reading. Recalibrated, got the original reading again, cleaned it again, and then got another off reading in another direction. In other words, this meter is only reliable if you have the calibration solutions at hand

Don't waste your money
Terribly inaccurate out of the box. Provided calibration powders would not dissolve in solution so it was even worse after recalibrating. I don't recommend this product. Bottled drinking water reading 5. I don't think so.

Failed after 4 months
Like another review stated, worked OK and then wouldn't calibrate below 9.18 so a waste of $30.
