I've had this meter/timer for quite some time now. I've used it as a darkroom timer, but never as an analyzer. I just never got around to calibrating it. It's supposed to be one of the finest color analyzers ever made. It comes with the power supply, the manual, the test negative, and the test print for matching during calibration. The print does seem to have yellowed with age and I suspect you can make a better color corrected print on your own from the test negative. It also comes with the under-the-lens diffuser for taking readings, a small extension cable for the safelight outlet, and the original power cable that goes to a European style electrical outlet (I think). I don't have the North American power cord for it, although it takes a typical computer power cable. I also have the original box.
It's very clean, and has one minor issue. The start button sometimes sticks particularly when pressed on the upper left portion. It actually doesn't affect operation as it sticks for a second or so and does not interfere with the timer operation. Apart from that, I've tested that the probe does respond to changes in filtration on my color head, as well as to light intensity changes. It works on both 110 and 220 volts, but is presently set up with a 110 volt plug on the back. This could be easily modified, I know as I changed it myself. As I've never actually used this as an analyzer I can't vouch for it's accuracy and am selling as is. I'm asking $150 + shipping + PayPal.
