This auction may be interesting, 3 scientech power meter heads. I think these are the sensitive calorimeter things with a 1mV/1mW output. If so, this would easily make 3 neat power meters. If they go relatively cheap, this may be something nice.

Note: It's not my auction (I'm on the other side of the ocean) and I can only make a guess at what they exactly are and in what condition. But I thought it's nice enough to post here, although a bit late.

Sorry... but they are not calibrated heads like the OPHIR or the
Coherent that the Kenometers use...
They output an uncalibrated raw current/voltage...

Yeah in order for these to be useful they would need to be calibrated with a certain meter, like a Scientech 365, 362, etc. Calibration either requires and a calibrated power source (and some circuitry know-how) or a laser and another calibrated meter.

I think this auction would only really be for someone if they have one or more headless Scientech meters and were looking for a compatible sensor to calibrate it with.
