  Model 43C SO2 Analyzer - See Model 43i


Reflective UV filtering offers superior sensitivity with multiple-range settings from 0-5,000 ppm.  The 43C is a benchmark for sensitivity, stability, and selectivity.  With its U.S. EPA Designation of EQSA-0486-060, the Model 43C is an industry standard for SO2 monitoring.

This product is no longer offered.
   Product Detail


The Model 43C integrates the proven pulsed flurorescence design of Thermo Scientific's Model 43 series with an enhanced electronics package and user interface.  The outcome is a sensitive, ultra stable SO2 analyzer offering network operators and research scientists unlimited troubleshooting diagnostics and data communications capability.

User software facilities include field programmable measurement ranges and SO2 concentration value storage by date and time.

Extended troubleshooting diagnostics now provide instantaneous indication of instrument operation parameter status including Pressure Flow, DC Supply Voltage, Internal Temperature, Reaction Chamber Temperature, PMT Operating Voltage, Lamp Intensity, Lamp Voltage and Optical Span Test.
