Comment: my first take...

(See in situ)


my first take...

having owned several analyzers and meters
ph/tds and a few others..
there's always the issues of calibration
to get proper readings...
preparation of samples is critical as well..
instruments must be cleaned, cared for and stored properly..
any analytic device and accurate results are ONLY as good
as the 'care' taken mentioned above..
I have my doubts about the 'everyman' concept in a practical sense...
it would be wonderful... but...
