In my case I just added a 2" glass window to the 2" T-Adapter nose piece. I also have an Ha 2" filter I can use instead. Effectively gives a sealed front end for Argon or Silica bags.
Also the distance separation from the chilled sensor means the window doesn't get quite so cold and prone to icing but I can use a warm air feed line from the TEC radiator and fan to add a little warmth across it if necessary.
Still waiting for delivery on the temp sensors from China so in a holding pattern present
