New Call-to-action
The Nova 5000 Series Portable Flue Gas analyzer has been designed for accuracy, reliability, ease of use and ease of service, providing a detailed analysis of flue gas composition. The 5000 uses customer replaceable sensors which respond quickly to the O2, CO2, SO2, CO, and NOx (as NO) present in the flue gas sample. The O2 sensor life expectancy is typically 3-4 years. The CO, SO2, and NOx sensor life is typically 2-3 years. The infrared CO2 sensor should not need to be replaced under normal conditions of use.
In operation, a built in sample pump draws in the flue gas sample through the stainless steel probe, 12ft. sample house, water separating filter, secondary filter, PTFE liquid blocker and flow meter then on to the gas sensors. The detected O2, CO2, SO2, CO, and NOx are displayed on separate large LCD meters with switchable backlights for use in dark areas. Optional with the Nova 5000 Series is a stack temperature reading.
A rechargeable 'gel cell' battery provides enough power for about 4-5 hours of continuous operation and the analyzer can be used while it is being recharged. A red LED tells when to recharge and a green LED verifies that it is receiving recharging power. The Model 5000 series case is rugged, dust and water resistant when closed. A built in printer, which also shows date and time, is optionally available. A built in data logger is also available which can be uploaded to a PC.
