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.
