RE: Happy New Year (pH Meters)

["Jason Sullivan" <jsull97@earthlink.net>]

Santa was good to me...

I have begun using the IQ120 silicon chip sensor pH meter by IQ Scientific
referenced by Ken Simolo.  I would support each of his observations:
- Extremely convenient.
- Good accuracy for my applications.
- Slightly slow response time (a heck of a lot better than test kits!!)

Prices are listed online.  Kit includes a nice holder as well.

Regards.
J Sullivan.

I would recommend the silicon chip sensor pH meters. They can be
stored dry and the electrodes are good for 10,000 - 20,000 readings.
Most of the standard gel pH electrodes (the kind found in most of the
small hand-held pH meters) last for 6 months to 1 year and then you
have to replace the whole meter.  The best price/performance that I
have seen are at www.phmeters.com - I have now used one of their's
for 18 months with no problems.  They came highly recommended by a
salesman who only carries standard hand held pH meters so he was
actually losing business by recommending them!  The electrode is
stored dry which is a very nice feature.  For measurements, all you
need is 1 - 2 drops of liquid.  The extra $25 to get the model 125
(if I remember correctly) is worth it because you get 3 point
calibration capability among other things.  During the last 18
months, my meter has drifted by only 0.1 pH units.  The only negative
is their cost but they pay for themselves in just 10 - 15 months as
compared to gel electrodes.
