Model 43i SO2 Analyzer | Advanced SO2 Measurement

43 i SO2 Analyzer

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.

Key Features:

High sensitivity and fast response time
Linearity through all ranges
Internal sample pump
Insensitive to changes in flow and ambient temperature

iSeries Advantage:

Ethernet connectivity for efficient remote access
Enhanced user interface with one-button programming and large display screen
Flash memory for increased data storage and user-downloadable software
Enhanced electronics design optimizes product commonality
Improved layout for easier accessibility to components

The Model 43i SO₂ Analyzer is also available with an oxygen sensor module.

The Model 43i with Oxygen uses paramagnetic sensor technology to extend the possibilities of SO₂measurement, reading, and reporting the concentration of oxygen in the sample stream up to 100%. Additionally, programming allows the user to correct the SO₂ reading for the amount of oxygen in the sample.
