APPLICATIONS

7240 Probe &
Heated Filter

Continuous analysis of flue gas for any combination and
range of O2, CO, CO2, SO2, NOx (as NO or NO + NO2) or
combustibles from combustion processes.

FEATURES
• Best value continuous flue gas analyzer
• Sensitive infrared detectors for % and > 1000 PPM CO, CO2, or SO2
• Long life electrochemical sensor for 10 - 1000 PPM CO, NO, NO2, and SO2
• Catalytic sensor for % combustibles
• Fast response time and bright digital readout for each gas
• Microprocessor based with push button or potentiometer calibration
• Easy to maintain modular layout
• Sample preparation includes filtration and continuous moisture removal
• 4-20 mA outputs for each gas measured
• Sensors are temperature controlled for maximum stability

OPTIONS
• Hi/Low gas, low flow, high vacuum, and diagnostic alarms available
• Isolated analog 4-20mA outputs available
• Cabinet purge system available for use in hazardous or high dust areas
• Auto-calibration with touch screen LCD display
• Ambient temperature package for operation in -20°C up to 55°C (-4°F to < 131°F)
• Stack-mounted heated filters and high temperature probes
• Large free-standing cabinets with latching doors
• Optional sample conditioning features include:
1) Continuous water prewash system for acidic flue gases that are
present but not to be analyzed (See Model 7300)
2) Heated stack filter for removal of dust from high particulate samples
(Model 7240), automatic blowback available
3) Calibration gas injected at heated stack filter
4) Multiple sample point sequencer which allows multiple samples
to be selected and analyzed (see Model 402AS)
