Thermostat for a DIY incubator

[enchinoman]

I use a 15 year old Helix system. Works great, however I use Herpstat for my racks and it would be nice to have the alarms on the incubator. I have a car battery that I hook up to a power inverter in case the electric ever goes out. I've only used it once for four hours and the temp never fluctuated. If I where to buy a thermostat now I would definitely go with the Herpstat 4, it has temperature and humidity sensors plus all the alarms and is the same price as if you where to buy their single thermostat and their single humistat separately.

Just on a total hijack, where did you get the inverter and is it Pure seine wave output? (what it takes to run both helix and herpstats) I have been searching for one that is cost effective but have not found one yet. Does yours have a transfer switch as well?

My Helix worked just fine. Really all you need is a proportional stat.
