PH tester and Jewelers Loupe?

I’m on amazon and will buy in the next 20 minutes. I need a PH tester and Jewelers Loupe…

Apera SX 620 comes with everything for $83…or the AI311 which is already calibrated?

No idea on the loupe…

The Apera are good meters I have the apera 20. As far as the loupe goes get one with the highest power.


I would suggest a usb microscope I have a jewelers loop and I purchased a usb microscope and it’s the difference between great and good. JMO.


Aspera 20 or aspera 60 will work great.
I spent a little extra and picked up the Bluelab ph pen.

Thanks everyone…I got the blue lab pen and cal-mag can’t get here fast enough…I skipped the jewelers loupe…I didn’t realize it was a lighted magnifier…I already have one of those maybe I should try using it…


Yes that is the one I purchased.
Best ph pen I ever had.
The pen reminds you to calibrate every 30 days.
And very easy to calibrate.

I just went back and bought the usb microscope…should’ve ordered it the other day. Thanks for the suggestion…
I didn’t know what it was or what it would do and just landed on a how to use video and was like sheez…and ordered

I’d get a stand for it. You will find it is a lot easier to get clear and steady photos.

What kind of stand do you have for your microscope? Do you set it up and zoom into the plants or do you get the microscope up I to the plants?

I got mine and I finally got it working and the pictures are amazing but I definitely need to refine my process…

Thanks for your help and info!
