Going to let this thread die now I do product testing for a living and have a tendency to monitor everything new. So here's a nice litt bunch of data loggers that are really simple to use and quite cheap. Good to diagnose electrical or temperature problems.

Temperature -35 to +80°C
(-31 to +176°F)
Temperature -20 to +60°C
(-4 to +140°F)
Temperature -40 to +125°C
(-40 to +257°F)

Humidity
temperature, dew point 0 to 100% RH
-35 to +80°C
(-31 to +176°F) * * *

Voltage 0 to 30 VDC

Process current 4 to 20 mA

Event, State, Count 3-28 VDC

Thermocouple
(no display) -130 to +900°C (J)
