Leybold-heraeus 554 70 BR1 BR2 device w/tube
For sale is a relic lab piece that we have been unable to determine the name of. Everything we know about it is listed below, along with part numbers and serial numbers, where noted.
This unit plugs into standard 110VAC.
It responded with the 'on lamp' turning on and a glow coming from the tube that is inside the orange shield.
The glow increased or decreased, when we adjusted the potentiometer next to the on/off switch.
Adjusting the other potentiometer had no effect on anything we could notice.
That is the extent of anything we did to 'test' this piece.
We are unsure what else may or may not be needed with the device, but everything we are including with it is pictured.
The 'Main Unit' has two labels on it:
We are including a power cord that fits a bit snug, but it is not the original power cord that came with this unit. There are no warranties or guarantees of any kind. Any shared knowledge on this piece would be greatly appreciated.
