Modems

Low temperature dialup modems

I'm looking for suggestions where to look for dialup modems with an extended temperature range of -40 to 85 degrees Celcius. This would be for a battery monitor at remote site. Most of the dialup modems we currently use only have the normal commercial temperature range. Any suggestions would be appreciated. Allan

Re: Low temperature dialup modems

Your best bet is to place the system in a box with a heater that works when the temperature is lower than 0 degrees.
