Re: ..water filter that works..finally.
TDS meter

pH meter advertising this meter for $17.00, but
the seller is charging $ 8.00 for shipping.

eseasons price is $ shipping and
a free packet of calibration fluid...
..and a tiny screwdriver for turning the tiny
screw to zero in the calibration setting.

I have used my pH meter several times a day for
about a year's pretty much dead on accurate..
about the most I've ever had to adjust the cal setting
when cross checking with the 7.01 pH solution is about
point 1. Not bad for a $20 meter.

* do remember to keep the sensor damp. I am too cheap
to invest in the "storage solution" that is recommended..
tap water will have to do...tiny bit of damp paper towel
inside the storage cap to keep the sensor from getting
overly dry.
