Super cryo cooler arrived today

cellphones).

do other experiments.

dhand (Hybrid 98 Cryogenic cooler, same as yours I believe). I have been se arching all over the internet trying to locate the software to control the unit through the RS232 port and I have been unable to find it anywhere. Do you have this software or know where I might be able to find it online? Sup erconductor Technologies is unwilling to provide it since I did not buy the unit from them. Any help you can give me is greatly appreciated.

Hi, this type of device is quite new to me and I have no experience with RS

-232 control software. My understanding is that this device has proprietary firmware which maintains a setpoint temperature which happens to be ~77K. I wish only to change that setpoint temperature but still rely on the firmw are to maintain the setpoint. Thanks for any help!

Not sure I did that via RS232. But why bother?

There is even somebody who simply used the cooler on a 60 Hz variac from the mains. As alternative to a power audio amp and PC signal generator I used...

To measure I use this:

So if you have the temperature and can set the drive voltage (I added a trimmer to that original thing between 2 wires to set output level). If you want to know which wires I can take a picture of it.

You could also control it by adding a tiny amount of voltage in series with your thermocouple. It would keep the setpoint, but the real temperature would be lower or higher

As they say: The possibilities are endless.
