PH pen

[kysmith]

Anyone heard anything about these? I want a PH monitor, but this might be a good substitute since I could check the PH so quickly and accurately by just dipping it in. I just don't want to pay the extra $$ right now for a PH monitor.

a real meter with a remote probe that you can leave in 24/7 isn't really that much more (like maybe only 20 bucks more?). i've never used a pen, but i've always wondered how you keep the sensor wet on the pen between uses.

yeah it's a big pain in the neck. mine got dried out all the time, and i really questioned its accuracy.

You just have to keep solution in the cap in between uses. But Matt is right , for a tiny bit mor you can get the meter w/ probe and they last longer , easier to calibrate , and just plain more durable due to not having to move them around as much...

Most pens come with a small sponge that fits over the sensor. They work well as long as you look after them, like anything else.
I had one of the pens and they seemed to be as accurate as my pinpiont.

OK I guess I'll splurge and get a legit monitor.
