My Thermochron arrived and I am very pleased with it lives up to all my expectations.
I have a presentation scheduled of its usefulness on Thursday with orchid exporters as they are using refrigerated air freight and ocean freight.

Have already done a couple of test runs and printed out charts with specific dates.
It was interesting to find out the temperature range of my air-conditioned apartment as it really did not jive with what I thought.
My air conditioner says a steady 27, but the range varies from 30 to 24.5 centigrade diurnally.

Have also verified that the data cannot be manipulated.
Either it is all there or the iButton is wiped clean.

Still trying to determine the usefulness of the added goodies - like the clock alarm and the bit of extra memory for general use.
