The Model 1100M relies on the Non-dispersive ultra-violet method of gas analysis and features a long-life mercury/phosphor UV source lamp. To satisfy the increasingly demanding requirements of industrial source gas sampling, the 1100M features a totally heated 150 degree C gas sample system. This allows direct monitoring of high water content, saturated flue gases, without loss of SO_2.

 

 

The Signal Instruments model 1100M Heated Sulfur Dioxide Gas Analyzer is designed for the continuous monitoring of SO₂ gas for pollution control and combustion research applications.

The gas analyzer has a totally automatic microprocessor-based operation including auto-calibration and auto-range . This makes the instrument ideal as a "smart" stand-alone unit or as a "building block" for systems integration via a RS-232 communications port or remote contact closures. Extensive automatic diagnostics and fully-configurable alarms are also integral to the gas analyzer.

A large multifunction, LED operator display provides gas concentration measurement, range, sample gas flowrate and the status of critical operating parameters and error codes. The interface is navigated by labeled pushbuttons, enabling the operator to quickly configure and control the gas analyzer's function. The unit features 19" rack mounting at 4RU height and a weight of 44 Lb. It has a dual voltage capability of 115 Vac and 230 Vac which is switchable from the rear panel.
