The amp is needed for thermocouples with the U3. If you use a silicon type sensor (e.g. LM34)
instead, then you don't need an amp.We had suggested the LM34CZ or LM34DZ from Jameco for $5 or
$2 each, o...

To make your own temperature probes, consider using the LM34 from national.com or digikey.com.
It is hard to beat for accuracy, cost, and ease of use. When you are using a voltage

Have you taken a look at the LAB-Tick amplifier board for the Ph probe?, looks like the input
impedance would work, just need to bias the Ph probe with +2.5 V to get full range output. As
to probe mai...
