The Thermo Scientific 43i-ANSCA SO2 (Sulfur Dioxide) Analyzer is a sophisticated instrument designed for the measurement of sulfur dioxide (SO2) in environmental air. Below is a detailed overview of this analyzer:

Key Features

• Pulse Fluorescence Technology: The 43i analyzer utilizes pulse fluorescence technology to measure SO2 levels, making it the first gas analyzer to adopt this method. This technology ensures high sensitivity and accuracy in SO2 detection.
• Measurement Range: The analyzer can measure SO2 concentrations in environmental air up to 100 ppm (parts per million). It offers a wide range of measurement settings, allowing users to ｓｅｌｅｃｔ the appropriate range based on their needs.
• High Sensitivity and Fast Response Time: With high sensitivity and a rapid response time, the analyzer can quickly detect and respond to changes in SO2 levels, providing real-time data for monitoring and control purposes.
• Linearity and Stability: The analyzer exhibits linearity across its entire measurement range, ensuring accurate readings regardless of the SO2 concentration. Additionally, the reflective bandpass filter minimizes photochemical degradation and enhances wavelength separation selectivity, improving the instrument's detection specificity and long-term stability.
• Built-in Sampling Pump: The analyzer is equipped with a built-in sampling pump, which facilitates easy and efficient sample collection.
• Oxygen Sensor Module (Optional): The 43i analyzer can be equipped with an oxygen sensor module that uses paramagnetic sensor technology. This module extends the analyzer's measurement capabilities, allowing it to read and report oxygen concentrations in the sample stream up to 100%. Furthermore, the programming function allows users to correct SO2 readings based on the oxygen content in the sample.
• Enhanced User Interface and Connectivity: The analyzer features a large display screen and an enhanced user interface with editable shortcuts for easy operation. It also supports efficient remote access via Ethernet connection, enabling remote monitoring and control.
• Data Storage and Software: The analyzer has a flash memory that can store more data, and user-downloadable software is available for data analysis and management.
