ST-1545 Sulfur Nitrogen Analyzer
Product Introduction:
The ST-1545 Sulfur Nitrogen Analyzer uses ultraviolet fluorescence method to determine total sulfur content and chemiluminescence method to determine total nitrogen content. It enhances the ability to resist impurity interference and avoids the cumbersome operation of the titration cell in the coulometric method and the resulting instability factors, greatly improving the sensitivity of the instrument. Key components of the system use imported devices, ensuring reliable overall performance. It is an integrated nitrogen and sulfur analyzer developed by combining chemiluminescence and ultraviolet fluorescence principles with computer technology. Complies with SH/T 0657-2007, SH/T 0689-2000, ASTM D4629, and ASTM D5453 standards. Suitable for determining sulfur/nitrogen content in liquids, solids, and gases. Widely used in power, petroleum, chemical, commodity inspection, universities, and research departments.
Features:
◆ The instrument uses chemiluminescence method to determine total nitrogen content and ultraviolet fluorescence method to determine total sulfur content
◆ The instrument's UV lamp, filter, mode dryer, data acquisition card, and photomultiplier tube are imported devices, ensuring accurate and stable experimental data with high precision
◆ Software operation is convenient and fast, standard curves and results are automatically saved, and data is never lost
◆ Computer-controlled data acquisition, detection, storage, printing, etc.
◆ Gas flow system includes mass flow meter control and float flow meter control (optional)
◆ Mass flow meter: All gas flows are controlled by electronic mass flow meters, gas flow is set and controlled by the computer without manual intervention (optional)
◆ PMT high voltage can be adjusted arbitrarily, calibration can be done with single-point or multi-point correction, operation is simple and fast
◆ Key components of the instrument use imported devices, overall performance is superior to domestic similar instruments, can replace imported products
◆ Simple operation, online help, problems can be solved at any time, data can be accessed, printed, and transmitted freely
◆ The instrument uses USB port communication, standard 24-bit data acquisition, detection signal is less than 1 microvolt
◆ Paid metrology certificate provided by the Institute of Metrology
