Flue Gas Analyzer
|
|
Industry Type |
|
Flue Gas or Emissions
|
|
| |
|
Continuous analysis of flue gas for any combination and range of O2, CO, CO2, SO2, NOx (NO or NO + NO2) or combustibles from combustion processes.
| |
|
- Best value continuous flue gas analyzer with modular sample conditioning
- Oxygen detected by either long life electrochemical sensor, high accuracy paramagnetic sensor or zirconia sensor, depending on desired accuracy and sample composition
- Fast response time and bright digital readout
- Microprocessor based with push button calibration
- Easy to maintain modular layout
- Sample preparation includes moisture removal.
| |
|
- Hi/Low gas, low flow, and diagnostic alarms available
- Isolated analog, RS232, RS485, MODBUS, and Ethernet outputs available
- Cabinet purge system available for use in hazardous areas
- One-step 'cal-now' button with touch screen LCD display
- Full automatic calibration with touch screen LCD display and low flow switch
- Cold weather package for operation to -5°F (-20°C)
- Cabinet coolers can be fitted to most models
- Sensors mounted in heated box for reduced drift
- High temperature filters and probes
Optional sample conditioning includes:
- Continuous water pre wash system for acidic fuel gases present but not to be analyzed (Model 7300)
- Nafion-Tube™ based sample dryer for high accuracy analysis of acidic samples, where NO2 or SO2 are to be measured (Model 7250)
- Heated stack filter for removal of dust from high dust load (> µ) samples (Model 7240)
- Calibration gas injected at heated stack filter to minimize discrepancies due to absorption of soluble gases.
- Multiple sample point sequencer which allows multiple samples to be selected and analyzed (Model 402AS)
