2 Hanna Ph Meters checkers, different reading

[Legal-Smoker]

I bought a Hanna ph meter about 6 months ago and I am having problem with my water Ph calibrated and had a friend that bought one from a thrift store and it just jumps around he said and I checked it and re calibrated it seems fine but Both meter are reset with 4.00 and 6.86 Buffers and they don't read the same when in the water and 1 would say 6.72 and the other at 6.89 that after I add Ph minus to the water and don't know which to believe.?
I have a water district just aright across the street and was thinking about taking these pens over and ask them to test my water, so I can test my pens to see which is right..!! Good Idea or just buy another expensive Ph tester..

I don't get it though because, my plant outside just get hose water and that plant is in a 5 gal bucket and in Old soil and she doing Great and I also have abuse her and she Raising to the sun!! My inside grow has to have the Ph 6.50 to 7.00 and the feed as to be just right or ELSE or there leaves are curling like Claws and show the abuse.. Maybe I should stop lowering my ph and see what happens to the inside plants.

Those Ph strips are they any GOOD.?
What do you suggest, Beside any Hanna.!!!?

You get what you pay for in a meter. I had a couple of those Checkers and the Primos they make too......back in the day. They cost about 25 bucks a piece and thats what you get.

Those em out and kick in for a meter from Hanna, Oakton, Milwaukee, Bluelab....etc.....that costs 75 bucks or more.

I have the Hanna HI98127 and its the shit for pH. A BlueLab Truncheon goes for around 135 USD.

Both worth their weight in gold (and dry buds).

You won't be sorry, I promise.

drops are the best. I have used a lot of different meters company bought for testing waste water after acid cleaning old ass compressors and they all fail. The probes go every couple months then the meter explodes and never read right again at some point. You need to keep liquid around to calibrate it so might as well just keep liquid around to test and just leave it at that.

my buddy just got some sort of hanna tri meter for 200 and he loves it so far.

The ph checkers are listed as +or - .5 I think check your instruction manual, under specs.
That means either one when fully calibrated could measure up to .5 off.

yep. $5 drops beat my >$200 electronic probe all day every day, never lost a crop due to drops, cant say that for the probe.

Thanks I am on the look out for a Better meter..!
I am going to check out the water district tomorrow and see if they check out water Ph. and go from there..

 

[Legal-Smoker]

What about those pool strip would that work for now til I can get a better meter.?
I have also seen on Ebay those Digital soil ph testers are they worth there money.?

Going Outside is Better then Inside, at least yea can use Hose water with out lowering or raising the PH.. At least that what I am seeing..

go to your local hydro store and grab a dropper test kit, its got a small bottle of solution, a test tube, and cap. less than 10 bucks even at hydro stores. gives readings that although cannot be 100% certain of the exact ph, are within .5 if your eyes are any good. Same or better performance as electronic, always reliable.

allowing your plants to have a light swing around optimal nutrient range allows for a more thorough uptake of the full amount of nutrients, not locking any out... at least in my experience.

the soil probes? I'm not a soil guy, I've heard they aren't worth relying on though.

 

[HighHead]

use ph drops to check the meter.

 

[nineblanc]

im wondering is it acurate enough to use that paper stuff and then it turn into an other colour?

Thanks I'll check them out!
I am NOT Fawn of those soil prong meter either, because they always says it at 7.00 ph.
I was more thinking of the electronic digital ones I seen on ebay..?

Is this any Good.?

I am looking at one of those Hanna HI98127 and hopefully there worth the price.! Time to save a little.

I had two Of the Milwaukee PH meters and they both sucked. They lie, even when properly calibrated. I learned over three years ago not to worry about PH. As long as it is close to 7PH the soil microlife will correct the PH. Now I only check my water PH about twice a year with the paper test strips. I threw away both off my Milwaukee PH meters years ago.

 

[reckon]

after spending probably $250 on PH meters and pens

I just use the strips now,...no calibration, the things are NEVER wrong, easy as falling out of bed to use (dip, and read), and at $6 for a 20 foot roll, I get about 4 years worth of PH testing.

now I just use the pens as a double check,.......wish I never spent the money on the meters/pens.

the thing that got me, was NONE of the "exotic fish guys" trust the meters/pens with their ridiculously expensive/exotic bozmani rainbows, arowana's, cichlids etc.......they ALL use PH test strips (litmus paper)

I no longer have PH troubles, I just use the strips.

unless you are color blind, or you don't mind spending $600 for a REAL PH test meter, I think the meters/pens are a waste of money.

I have used real nice lab meters for work and you still need to maintain them then calibrate. So with liquids still needed or drops around to check the meter why not just stick with drops? I just had a nice oakton ph-5 die but I don't think I will get a new one, I did have a new probe on hand but it's the meter. With work I maybe went through 2k in ph meters before I just got strips for there drops are better for this kinda stuff I think. I find the drops easier to tell smaller changes while at work I just needed it close to 7 to dump in the drain.

Your pH's are reading fairly close to each other. You will never get two pH meters to read exactly the same, never. Point one seven ain't that far apart.

 

[Legal-Smoker]

Well Hell I think I buy some of those ph strips for the pool til I can get the money up. But that Not going to Happen because we are talking about moving to Arkie to be near our Kids.!!

Arkie must become a MMJ State..!! NOW!!!!!!!!!!.. California is going to Lead the way the Legalization for ALL States Nov 1..

I have not worried too much about PH and never tested anything. Never had any problems. One problem i could see is your water supply if it's PH is off as this makes things very difficult to diagnose not knowing where to start. But even then this does not warrant buying one of those fancy things that will cost you an arm and a leg when drops will suffice.

I keep reading that the membranes of the pens go out and have to be replaced every few months of so. Then there is the cost of having to buy the calibrating liquid, storage liquid that is not added to the total cost of owning a pen. All seems to be lots of money for information that could be obtained, with a reasonable degree of accuracy compared to the meters, by means of a few drops of PH test liquid. Built in obsolescence as well as built to fail to keep you buying them a few times a year.

Fancy PH meter and dropping it would be a BIG Sniffle.!
For now I'll use one of those pool strips and be done with it for now as those are as Good as any meter I believe and that it work for my pool and my first grow and did Good then..

 

[FreezerBoy]

I tried strips for a while. They were 0.5 lower than the drop readings but at least they were consistently wrong. When given a number of readings from a number of devices, always trust the drops. $5 at any aquarium store: no batteries, no calibration, accurate to 0.1
