If you had to determine the sulfur content of steel 450 times a shift, could your lab do it? Only if you had a

LECO 60-second sulfur determinator

You may never be faced with such a herculean task, but if you were you could depend on our new IR-32 Sulfur Determi­ nator to do the job accurately and with reproducible results. Its infrared detection system cuts to 60 seconds or less the time required for automatic sul­ fur determination in iron, steel or other materials. Results are displayed as percent of sulfur on a direct digital readout, with the range for a 'A-gram sample .0002% to .2%. Simple to operate, the new LECO 60-second Sulfur Deter­ minator has a built-in digital weight compensator which per­ mits easy adjustment for sam­ ple weight variations, to elimi­ nate time-consuming manual calculations. There is no titrat­ ing, no solution to prepare or handle. And LECO solid state design increases calibration sta­ bility and simplifies service.
