Dez: the 104B’s have input modules for voltage and current, so can also measure instantaneous power and power quality.

Roman: Ok for a small turbo.  See the next set of photos with several visible from the ends, quite small diameter.  Pfeiffer TPH series.  The Keithley is a DC precision volt meter.  Can also be set up to read in Amps if you use an external shunt and measure the volt drop across that.  But its not a power meter so cannot measure volts and amps simultaneously.

More photos below:

2: Turbocontrollers, Turbopumps, KF/NW vac fittings
3: Vac gauges and readouts

 If any American members want variable ballasts here's a couple  https://www.ebay.com/itm/256434332451?  https://www.ebay.com/itm/387484802366   Heres the sort of lamps the last one is meant for    https://www.ebay.com/itm/354869576884?  https://www.ebay.com/itm/225011148266? https://www.ebay.com/itm/144221903968?

I think there's a few members here that have 700 or 2000w lamps that would probably want ballasts and the 35w(230v?) and (50hz?) cwa ballasts are probably worth saving.


Are there any industrial surplus places around there?

I'm assuming the ballasts are mostly 230v 50hz and you probably too busy with the move to deal with shipping tons of stuff internationally?

Won't you need the vacuum stuff for led filament lamps?

Don't forget to check the attic/basement/closets on the way out.

edit; Any of those 3 pin bayonet sockets?

Hello James,
thank you for sharing that stuff with us before it goes in the trash. As you know I am still trying to find a possible date to visit you, it sadly is not as easy as antixipitated.

Is there still a power meter available? If so I would als be interested din one. I am also barticaery interested in HMI lamps 2.5, 4, 6, 12kW especially from Osram, as well as UV sources... Also variable electronic ballast would be very helpful for myself as well as a few G38 Lampholders.

Best regards,

Alex

Thanks! Of course I would like also pick some regulators, precision needle valves, vacuum gauges! - stuff very useful with a neon plant. Though logistics is a bit questionable for sure...

James do you have any ballasts left for 40W 2ft tubes? I’m looking for a couple of these.
Also for 115W and 140W.

Thanks
