The most reliable device I’ve had has been the
BlueLabs guardian - it goes on sale every now and then

I too use the Apera’s… descent meters, seems accurate, great build quality, battery lasts ages, easy to calibrate… only thing I’m missing is a backlight.

I would love a few Bluelab Guardian’s, but that price scares me away as i would need two… one for each reservoir.
How long have you owned one, how often does it drift and need calibrating?

Exactly. I went through a million garbage Amazon pens before I switched to the drops years ago and haven’t had a problem since.
I’ve had mine for about 3 years now , I’ve replaced the PH probe once , only because I dropped a gallon of nutes and cracked the first one ,
But it doesn’t drift to often, but I do calibrate every 2-3 weeks just out of habit

How far apart is your res? You could use the same one for both just bring it back and forth, it is a wall mount but it’s not entirely needed

I have thought of that… and probably the way i’d end up. Two 12 gallon res right next to each other. Certainly possible and i have a spot behind them to mount already placed.
I was looking at cheaper alternatives on amazon but never pulled the trigger for lack of trust in the products.
Know of a decent product maybe half as expensive?

It has long cords so could mount it above both, I have mine 5 foot above my res & it will reach the res and a bucket 2-3 feet away still

I’ll do some research and see if I can find something
I’ve been using mine for 5 years without a hitch.
I don’t think I paid that price though.
Maybe $250

How do the drops work with nutes? I tried pH paper and it doesn’t work with nutes not the same as drops I know. I am curious which drops do you recommend?
I paid like 220 originally, it’s a great device , sucks inflation has hit all of growing as well

It is a great unit.
I had a Hanna multi pen before that and it was such a pain to calibrate.

Milwaukee all the time.
I bought my first one 21 years ago for PH…still working perfectly
amazon, yellow, $10.00 ph pens work fine. bought two from diff sellers and glued em side by side for accuracy/comparison after calibrating em.
i pull the caps off one handed and dip em for a reading then slap em on my jeans to knock the water off, cap em and bobs your uncle, for 2 years, now. 6.4 for the win!
