ZSN-2000 sulfur and nitrogen analyzer Introduction:
The instrument uses ultraviolet fluorescence method (S), chemiluminescence (N) principle, determination of the sample sulfur / nitrogen content. The working principle of reference ZDN-2000 chemiluminescence nitrogen meter and ZDS-2000 fluorescence sulfur analyzer. Scope of application: Suitable for determination of total sulfur / total nitrogen in crude oil, distillate oil, LPG, plastics, petrochemical products, foodstuffs, etc. Meet the standard: SH / T 0689 Determination of total sulfur content (UV fluorescence method) ASTM D5453; SH / T 0657 Determination of total nitrogen (oxidation combustion and chemiluminescence); ASTM D4629 Features:
1 Windows operating platform, man-machine dialogue, easy to operate.
2 micro-current detection using the first patented product - sulfur nitrogen detector, the instrument has a high sensitivity, low noise, linear range, anti-interference ability and other advantages, is the most advanced sulfur and nitrogen content analyzer (Patent No: ZL02263530.0).
3 high-pressure arbitrary regulation, standard calibration can take single-point calibration, convenient, fast and accurate.
4 the use of international popular circuits and imported devices, machine performance better than similar domestic products, and can replace imported Technical Parameters:
