Hi,

expected low of 1 degree and with a high pressure system about to park itself over the state, I can finally measure the peltier cooling system.

I hope to have the new one up and running in a couple of weeks, so i can then run the test again.

The current one has only one peltier, there is no perspex insulator and the aluminium cold plate disc is too big to fit inside the mirror cell cavity behind the mirror.

The new one will have two peltiers, a perspex insulator that will seal the base and also the cold plate will fit in behind the mirror.

graphs from 1/2 hr measurements to come.....
