Carbon
160-second SULFUR DETERMINATOR-IR-32 Infrared detection cuts to 60 sec onds or less the time required for sulfur determination in iron, steel or other materials. Direct digital r e a d o u t displays results as per cent of sulfur. No titrating, no solutions. Range for Vi-gram sam ple .0002% to .2%.
Direct reading, rapid HYDROGEN DETERMINAT0R-RH1 Requires only t w o minutes for complete hydrogen determina tion in steels, t i t a n i u m and o t h e r alloys. LECO Impulse F u r n a c e f u s e s s a m p l e in a s i n g l e - u s e graphite crucible at 2500° C. Re sults are displayed on electronic digital voltmeter as ppm. Direct reading range for 1-gram sample 0.1 p p m to 200 p p m .
| Dual-Range CARBON DETERMINATOR-DR-12 Provides accurate readings in a range from .005% to 5% for a 1gram sample. Front-mounted con trols permit technician to vary combustion time and select high or low range. Direct digital read out displays results as p e r c e n t of carbon. All three n e w LECO determina tors feature solid state design which increases dependability a n d simplifies s e r v i c e . Built-in digital weight c o m p e n s a t o r s per mit adjustment for sample weight variations, eliminating time-con suming m a n u a l calculations. See all the n e w LECO deter minators at the Pittsburgh Conference, booths 1502 / 1506.
