Thermometer

Hi,

Does anyone know where I can get a kit for a thermometer with PC
connectivity for logging at predetermined intervals (anywhere from 1
sec to 10 seconds)? I've seen some, but the maximum temperature
reading is too cool - I require temperature readings around 250C to
260C, but nothing below 10C.

Does something like this exist?

Cheers
Ed

** Both Jaycar and DSE sell digital multimeters with inputs for a K type
thermocouple ( -20 to +300 C) with RS232 interfaces. Cost is around $150,
all up.

I used one of those to measure battery voltages and after a certain number
of readings it caused an overflow and crashed my computer. Try 'em before
you buy 'em.

Thanks for the info. I'll pop into Jaycar and have a look.

I'm curious. What kind of "overflow" could crash a computer? Surely
not a buffer overrun on a relatively slow serial port? Was the
supplied software, if any, DOS based?

I'm not sure. I was taking a reading every minute with the idea of observing
when the voltage starts to drop off (under load).
I don't know how many readings it was, maybe 256, when each time it took a
reading a error window would appear on the screen. The error windows
couldn't be closed and just kept appearing until the computer crashed. I'm
using Win200 on a fast computer. Luckily I had only borrowed the meter and
so I returned it to it's owner. It was an unusual brand with a rs232 socket
in it. The software was on a floppy disk that came with the meter.

In that case, try finding the process through task manager and killing
it. It would be nice to know the error!

 

I don't have the meter any more. I had only borrowed it. It was one of those
Byrmen? ones from dick smiths.
