SG750 Stack Gas Analyzer
Model SG750
Stack Gas Analyzer
Product Information
The SG750 Stack Gas Analyzer consists of an infrared gas analyzer, a zirconia
oxygen analyzer, and a
sampling unit.
It can simultaneously measure up to 5 components: NOx, SO2,
CO2, CO, and O2.
The use of interference compensation in the analyzing section virtually eliminates
the effects of interference from other components. The SG750 features many functions
including autocalibration, conversion to O2 values, averaging,
and high/low alarms. It is used for measuring and monitoring emissions from various
types of boilers and waste incinerators.

General Specification for SG750 |
Features
| * | Simultaneously and continuously measures concentrations of up to 5 gas components NOX, SO2, CO, CO2 and O2. |
| * | The use of interference compensation in the analyzing section virtually eliminates the effect of concentration of any gas component on the concentration readings of others. |
| * | Adopts a double beam infrared analyzer, a Zirconia oxygen analyzer meter or paramagnetic oxygen meter with high sensitivity and excellent long-term stability. |
| * | The maintenance type on the front saves space. |
| * | High sensitivity and wide dynamic range, allowing for switched ranging of up to 1:25 and range can be changed. |
