S got ours from All-Electronics.  www.allelectronics.com

Catalog number PM-21.  It needs an external 9V battery, so you need to
find a little box to put it in.  S also put in a double pole triple
throw switch, so we can monitor each of our batteries and also switch
it off.

We live in SoCal, so I can't tell you how it behaves in very low
temperatures.
