I've been using these meters for over 10 years. Buy this and you'll never buy another unit again!

P.S. Don't buy the cheap imitation you can also see on Ebay and other places.....they are crap too.

Try our Ultrapen PT2: "The Ultrapen PT2 is compact, reliable, easy to use and so far seems very durable while riding in its carry case between measurements. I use it daily and it reliably delivers PH and temperature. Though I have not calibrated the unit yet, the instructions are quite clear and easy to understand. I am purchasing my second PT2 today." Product is here: http://www.myronlmeters.com/Myron-L-PT2-Ultrapen-Multiparameter-pH-temperature-p/dh-up-pt2-ss.htm

I use a BLUELAB PH PEN.

Holds true for at least 2 weeks but I always recal every 10days though.

I have to adjust my pH on the Nutradip maybe twice a year.........but my feeling is if you are paying over $125 for a pH pen, for $50 more you can get the ppm reading too, which is almost as important. It's also a continuous unit, reading pH/ppm 24/7 which is very helpful.

I used the cheapo Milwaukee ph600 last year and it worked pretty well. I let the probe dry out during the offseason, and while I did feel the earth rumble a bit, I'm using it again this year. It still seems to work pretty well. Go figure.
