ph tester needed

i have bought 2 electronic ph testers that dont seem to work, can anyone reccomend a ph tester that they use
 
you give the best links ATU , the birds must know I'm talking to you they keep circling me ,you know hootie chases buddy around me but is to slow for buddy lol
 
I use the same meter as ATU and it is real important to not let it dry out cause its junk then , bring it in to a store and they will test it for you and show you how to calibrate it if you dont know. and it takes longer than 15 seconds for ph to balance out .In fact how long does everyone leave there ph meters in nute mix before taking the reading , I go until it stops changing 20 seconds
 
Het RC...I had a Nutradip meter that I used for fifteen years, it needed new probes every few years, even though they were well looked after. As everyone will tell you...you can't let them dry out and you should store them in pH 4.0 test solution or storage solution. I'd recommend that brand based on my experience

My new meter is a BlueLab combo meter. I've had it for about a year and a half, and it's great, but it displays one output at a time. I liked the Nutradip better, it displays all three reading simultaneously, and doesn't run on batteries, which may or may not be an advantage I suppose.
 
never failed me yet.

i have the same that ATU and OJH have but i also have a cheap yellow chinese one and the yellow one its always spot on and needs no calibration, the fancy one needs calibration once a month at least. buy a cheap yellow one i would say
 
i too think the strips are the best choice, specially the ones with the 5-9 ph range. i cannot get them locally and/or cheap
 
Yes, I test until I reach stability. I swirl around the water with the ph pen and test while mixing the water around. This ensures PH uniformity through out the medium. Then I clean with DI water and store ph probe bulb in a storage solution. Calibrate 1-2 per year.
 
If you are testing 1-2 buckets, sure. I can see that. Now if you are testing 100 buckets, that would require way too many man-hours to use the strips.
 
Agreed, my cheap $10 no name brand yellow PH pen has lasted me about 5 years now. I went a year with no calibration at all and the pen was only .1 off the calibration solution rating.

You might try soaking them in distilled water for about an hour. I resurrected one of mine with this procedure. Give it a shot you've got nothing to lose.
 
I think soaking in pH 4 calibration solution or KCl would be better. Based on what I've read, keeping a probe in RO or distilled is what screws them up. Oakton, BlueLab, Hanna....all of them say the same thing.
 
Some manufacturers recommend soaking in distilled water. I did purchase MA 9015 pH electrode storage solution, but I prefer neutrality. This method has worked on two different manufacturer’s pens. The results have proven satisfactory for me.
 
Could it be that the “high end” manufacturers just might want to sell you expensive solutions? I would need to see the science to change my mind.
