Data logger for temperatures ?
I love data logger and plotting with them temperature curves ...
Unfortunately my old one dates from 1992 and works with a 
"DOS"-operating system and no USB of course.
a  COMARK, KM1400 Serie MkII Datalogger,

Want to buy a new one, came across the  handsome TESTO 177-T4, 
www.testo.com,
4 sensors possible, temp. max 1000°C
costs 310€, plus 90€ for software and adapter,  plus 16%Tax, (for 
temperature sondes I can use my old ones)
i want to use it to record temperatures on my low-cost retort kiln 
(charcoal production).

Anybody has some recommendation buying something else before i spend my 
money for this?
Thanks
