Jeff has a pretty good point =E2=80=93 if you =E2=80=98assume=E2=80=99 =
the instrument is accurate at birth and the readings are consistent, you =
might just be OK.=20
=20
An additional thought: given the relatively low cost to make and the =
relatively high level of importance to you, you might want to make two =
[or more=E2=80=A6] from the get-go. Then, you would have both a spare =
AND something to compare!

It may not be as important to be accurate as it is to be repeatable. If =
the machine is working and you get a reading, then as long as you get =
the same reading, you could assume the machine is working at the same =
level.

Pat, have you considered making one? A raspberry pi or Arduino base with =
an inexpensive sending might do the trick.
