This Leybold Ul100 one-button remote is used, refurbished, and is offered with a 30-day guarantee. It is in very nice condition.
Compatibility:
This remote will work with the UL100 firmware version 1.7; I have a copy of the firmware and I can send it with the remote if required. If your UL100 has firmware 1.5cp then you should have me send you 1.7, since 1.5cp is designed to allow the two-button remote to control the UL100.
If you have a UL100 Plus this remote will still work but you will not be able to go to vent or standby if you are in measure mode. The leak rate will still be displayed and you will have audio. Pressing the button will take you from standby to measure.
These remotes were available used from Inficon for $2500; there are no more available.
