The Nova 311 Series Portable SO
2
Analyzer utilizes a reliable, customer-replaceable electrochemical sensor which responds quickly to the SO
2
present in the flue gas sample. Its life expectancy is between 2 and 3 years. The pre-dried gas sample drawn into the analyzer by the sample pump is filtered, and then indicated on the flow meter. The cleaned sample then passes through the sensor chamber where the SO
2
is detected and displayed on a digital readout.
A rechargeable battery powers the pump and electronics for about 8 hours of operation. The analyzer can still be operated while it is being charged. Recharger is included.
