Application

Electrochemistry

Measure SO2 in ambient air up to 100ppm with the Thermo Scientific Model 43i SO2 Analyzer, the first gas analyzer to utilize pulsed fluorescence technology to measure SO2. Reflective bandpass filters are less subject to photochemical degradation and more selective in wavelength isolation, resulting in both increased detection specificity and long term stability.

Advanced Detection with Ultraviolet Fluorescence

The Model 43i employs ultraviolet fluorescence as its core detection principle, ensuring highly sensitive and selective measurement of sulfur dioxide concentrations. This method provides rapid response and excellent noise performance, making it suitable for both high and low SO2 environments.

Designed for Precision and Reliability

With features including a corrosion-resistant chassis, stainless steel sample cell, and 1% linearity and accuracy of full scale, the 43i guarantees durable, dependable operation. Its internal microprocessor control and dual range, auto-ranging capability further enhance measurement flexibility and reliability.

Comprehensive Data Handling and Connectivity

Store up to one year of 1-minute SO2 data internally, and choose from multiple analog and digital output options such as Ethernet, USB, RS232, and RS485 for seamless system integration. Programmable alarm relays and an intuitive display offer complete monitoring and system status at a glance.

FAQ's of Thermo Scientific Model 43i SO2 Analyzer:

Q: How does the Thermo Scientific Model 43i SO2 Analyzer measure sulfur dioxide levels?

A: The Model 43i uses ultraviolet fluorescence detection, which involves exposing the sampled gas to UV light. SO2 molecules fluoresce under UV radiation, and the emitted light is measured, delivering accurate SO2 concentration readings.

Q: What are the main applications for this SO2 analyzer?

A: This analyzer is widely utilized in ambient air monitoring, stack gas monitoring, and environmental monitoring. Its broad measurement range and robust data handling capabilities make it suitable for industrial, environmental, and regulatory compliance settings.

Q: When should maintenance be performed on the Model 43i?

A: Routine maintenance, such as checking the sample pump and replacing filters, should be performed per the manufacturer's guidelines or when the analyzer indicates reduced performance. Frequent checks in harsh environments can ensure accuracy and longevity.

Q: Where can the Model 43i be installed for monitoring?

A: Thanks to its durable, corrosion-resistant chassis and operating temperature range of 5C to 40C, the analyzer can be installed in indoor laboratories, process control rooms, or sheltered outdoor monitoring stations, as long as non-condensing humidity conditions are ensured.

Q: What process does the analyzer use for data storage and retrieval?

A: The Model 43i features internal data storage, capturing up to one year of 1-minute interval SO2 data. Data can be retrieved locally via USB or remotely through Ethernet or serial communication (RS232/RS485), compatible with standard data acquisition systems.

Q: How can users benefit from the analog and digital output options?

A: With both 0-10 V and 4-20 mA analog outputs, plus Ethernet, USB, RS232, and RS485 digital outputs, the 43i allows easy integration with SCADA systems, data loggers, or process controllers, enabling real-time monitoring and alarms for process optimization or compliance reporting.
