The HSY-0303D fully automatic sulfur content analyzer in additives (coulometric method) complies with the standard: SH/T0303 for determining sulfur content in additives. This instrument is suitable for samples with sulfur content greater than 0.1% (m/m), such as lubricants, heavy petroleum products, crude oil, petroleum coke, paraffin, and sulfur-containing additives. The instrument features a rational structure and ease of use, employing an automated tubular furnace experimental method. Once the experimental program is set, the instrument will heat and move as required. It utilizes super-insulating materials, enabling it to operate normally at high temperatures.
