Thermostat question for homemade incubator

[desertgecko]

Hi, hope someone can point me in the right direction! I've finally managed to have a decent look at my suspected gravid female and I'm very sure she is It's great but I haven't got my incubator set up yet. I've got a poly box arriving early next week. I've got heatmats, temp/humidity gauges and tubs etc. I just need help with a thermostat. For some reason I go blonde with these and can't figure them out. I've got 2 kicking around the place but I don't mind buying a new one if I know its right. There's 2 on this website here and here. Are these the kind I need? I only need it to keep the heatmat at the correct temp. The second one looks better as I can see it has a dial so I can set it to the temp I want, but it says its 'an on/ off switching device' which is not good right?

Thanks for any advice!!!!

Ok, after a search people mention pulse stats, like this one http://www.livefoods.co.uk/product_info.php?cPath=83&products_id=152 I'm confused now lol

I would go with the pulse thermostat. Imo its the bst way to keep your incubator at a consistent temp throughout incubation..

Ive had nothing but great results with hardly any temp fluctuations..
