Apera pH 20 all day mate you can’t beat it.German tech

cleaning/storage solutions often overlooked,some pens have slightly different storage conditions.distilled water/ph7.dont let the probe dry out is key.
and yellow aint worth the £4 i paid for it

i got a Hanna pen now https://www.autoflower.org/threads/hanna-instruments-hi-98108-ph-pen.68225/
good luck n keep er lit

Yeah Archie is bang on I use Vitalink solution when you get a good meter look after it!

Cheers everyone, have ordered a ph 20. Will see how I go. I wasnt aware that the probe was supposed to be kept wet! That's good to know. Again thanks everyone

some meters can be slightly different depending what material the lil electrode bit is made of,so the storage conditions can be slightly different.give the destructions a good going over
9 outa 10 pen fails come from the probe drying out.
what it says about my pen

Cheers, it arrived yesterday. It says to rinse in distilled water, after use. Would de-ionised water suffice? Or maybe the fancy coca cola water. It's called smart water and is vapour distilled but has vitamins in so maybe not for the best.

I bought a nutri+ pen a couple months ago. It was bout 25$ Canadian. It's been awsome so far havnt had to recalibrate it in a few weeks. First feed of the week I test it in calibration solution and it hasn't moved. Great choice if you don't wanna spend the money on an expensive one.

i think the rinsing before/after use is,technically to get a more acurate reading in theory.but as it goes to 2 decimal places its acurate enough
i have to be honest and say a run under the tap before use is what i do.but i try my best to keep the lid topped up with storage solution.
de ionized water is pretty pure,the + ions have been removed.distilled water has been boiled and condensed,in theory a smidge cleaner than de ionized water.
pinch of salt... de onized will do
good luck n keep er lit

Thanks @archie gemmill , that makes sense to me! It's a nice piece of kit so I want to make sure its looked after.
