It is for a Gas or liquid Chromatrograph. It
communicates to the GC via
HPIL. ( Serial 2 wire loop)
Most have been replaced with PC based data systems.
I seem to recall HP Integrators also being used with
Fairchild (later Schlumberger) ATE systems. Later
replaced by VAXen and Fastnet (has anyone else used
Fastnet?).
