I recently purchased this old commercial blend unit off ebay.
It was advertised as Sterex, but that name only appears on the probe and needles it was supplied with. The only name on the case is “BlendeTTe”, and on the reverse, the address:
…so it’s doesn’t seem to be anything to do with CTI’s Blendette+ from Holland.
It’s quite big - just over 18" wide, heavy, and solidly built from 1.5mm thick steel plate.
According to a date sticker inside, it’s about 24 years old. It’s completely solid state, and has no timer.
It has separate controls and meters for RF (0-50µA) and DC (0-1mA). Both sections appear to be working.
Connectors on the front are for the probe and indifferent electrode, and on the rear for a single foot switch.
I can find absolutely no information about this machine online, so I wondered if any of the people here had come across it before?
