HP Integrator calculator on ebay? What is this?



Has buttons and prints. Any idea what this was for? What year?


it is an integrator (finding the area under a curve) for a gas chromatograph instrument.


Here's the lower tech version :-)


Brings up memories as we used those for HPLC and alike 25 years ago in my apprenticeship.
