The HM Digital EC3 does what a PWT and an HM Digital COM-100 does, only
without the decimal place.
Checking for PPM with a meter is an erroneous process to start with, so
I'm not sure why the accuracy of a decimal place while using a yard stick
to weigh something is all that important.
Sorta like trying to get a kitten into focus...hey...it's fuzzy, ok? But
you know were it is and about how big it looks [till it gets wet]
EC3 $30 [free shipping]
COM-100 $55 [free shipping]
PWT ~ $57 [plus shipping]
Might find a better deal on ebay.

Hello,
I'm looking for any thoughts on meters to check the ppm. Someone told me
you needed the Hanna PWT that costs about $60. I found a Hanna Primo for
half that. The fellow that told me about the PWT says he checked the
Primo and it wasn't accurate. I contacted the company that sold it to me
and they said it basiclly has the same component inside as the Hanna
PWT. I would like to be able to be fairly certain what ppm I'm
making. Any comments on this is appreciated.
-Thanks Gary
