What about this pH pen/meter ?

[LuciferN]

Here is one pH pen I would like to buy to be ready for this summer to grow in soil (will be my first grow). Can you please tell me if this is any good for me or if I have to look for something else ?

That will work, but you will have to find calibration solution that is 6.8 as opposed to 7 and such. Find a pen that calibrates to 7.

Well I've found another pH tester: PH Meter Stick Wand Waterproof Hydroponics (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=250191685550&ssPageName=STRK:MEWA:IT&ih=015)
I was just wandering, can I really use this pen for soil testing ?

[growbe]

No you can not. In order to test soil ph you will have to spend some bucks on a quality meter. What growers do is just buy a digital ph pen and test run-off water.
Here's a great pen from a great company. This pen along with some 7.0 calibration solution and storage solution and you are good to go.

i bought this ph truncheon knockoff and it is working good for me
it does take the 6.86 solution and got it online for 10 bucks
you can do a soil runoff test. ph the water to 6.8 and collect some water from the runoff. keep on flushing out til the runoff is collected and at 6.8

heres a good video on the site to explain even better about ph meters and ph testing

I bought from this outfit and they included free calibration buffers. They are also a real brick and mortar store and therefore provide good customer service.

I bought my Hanna EC/PPM meter from these guys and was completely satisfied. Super fast shipping too.
