SULFUR DETERMINATOR WITH DIGITAL DISPLAY
Model No. 765-100
The LECO DB-64 fully au tomatic Sulfur Titrator con f o r m s to A S T M M e t h o d D1552 a n d can be u s e d to determine sulfur content in those oils normally analyzed by the bomb or quartz tube method. Results, as percent of sul fur or ppm, are read directly from an e l e c t r o n i c digital display. A u t o m a t i c w e i g h t c o m p e n s a t o r option elimi nates any additional calcu lations. Range is from 2 ppm to 1 0 0 % w i t h a c c u r a c y of ± 4 % of sulfur content and, total analysis time for most fuel oils is only 4 minutes. Combustion at the 1650° C temperature possible in the Induction Furnace is so com plete t h a t the r e s u l t s dis p l a y e d i n c l u d e the sulfur c o n t e n t of any a d d i t i v e s present in the sample.
