PH Meter

Hey everybody.... I recently purchased a PH meter through an online store. It's a milwaukee PH 600. It was pretty inexpensive. I'm going to buy a nice all in one meter eventually. This is my first grow so I'm fairly new to all this. My question is how often do you need to calibrate them? I've had it for about 2 weeks now and checked it 3 times. Every time it's off by about .3-.5? I keep calibrating, and it keeps changing lol. I'm using 4.01 and 7.0 buffers.

Depends on the meter. I've had mine well over a year and it is still completely accurate.

as tip top said plus i would not buy an all in one meter, i pressume you mean a ph and ec meter. you would be better buying 2 seperate units then if it goes wrong your not stuffed for both. plus its not that much dearer buying the two.

If this post ends up a double, sorry. I think I wasn't replying right. Sounds like I may have received a defective meter then Tip Top? Or just a shitty one. Lucifer, that makes total sense in buying seperate ones. A friend of mine suggested it. But when your rollin' in it lol. I also accidently bought a TDS meter. That's only in hydro though correct? SO many things to buy lol......

i myself am tight with the dollars just now, so bouth a cheapo digital off of ebay, will let everyone know what like it is when it eventually arrives via snail mail.

even if it does me a few months that will be fine, just need it until am back in black.

(insert AC/DC puns here)

The most important ? has been missed. How are you storing your meter between uses?

The Milwaukee was the first pH meter that I bought too. I calibrated it once every couple weeks and it was off about the same amount. I agree with the others as far as getting separate meters. When I accidentally let that Milwaukee tip dry out and needed another one I got the pin point meter and have had that a couple years now.

That tds meter can be used in soil grows. Use it to measure the amount of nutrients in you water before you pH.
You can also collect the run off from the pots and measure that but most of the time people measure pH that way.

how should one store ones digital PH mtere betweens ones usage?

Either in a storage solution or tap water. R/O and distilled water is a no, no.(as far as storage goes) Or as I do, just leave it in the res all of the time. If you allow the probes bulb too dry out it pretty must junks them. As Cruzer mentioned above.....

Bugger. Now I'll always be paranoid about screwing up my cheapo PH meter lol! ha ha ha!

great

I've been looking at the same Ph meter. I just found out the one I have is broken so Ive been flushing plants that didnt even need it. it wasnt till a friend brought his to me to use did I detect the problem. I hope the ebay ph meter is worth it.

Wow lots of replys cool. I actually use it daily. Should I let it sit in the buffer solution? I actually checked it again yesterday, and it was fine.

most of them come with a cap that has a sponge and storage solution in it. rinse it off after every use and keep it wet. And when you decide on another ph meter, look into hm digital can be had for about 77 bucks, nice meter for the money. Can get a replacement probe, auto calibration, and waterproof.

Yup it's been a few weeks. I've been storing it in the 7.0 measuring solution ever since I read the helpful hints. It's still is a piece of crap lol.......
