New Call-to-action
The Nova 320 Series of Portable Flue Gas Oxygen Analyzers utilize a reliable, stable oxygen sensor which responds quickly to the oxygen present in a flue gas sample. Its life expectancy is between 3 and 4 years. The sensor is very easy for the customer to replace and at a reasonable cost.

A rechargeable ‘gel cell’ battery provides enough power for the pump and electronics for about 20 hours of continuous operation. The analyzer can still be operated while it is being charged. A red LED indicates when to recharge and a green LED indicates that it is receiving recharging power. The analyzer is supplied with a 12 ft. sample hose and a stainless steel probe.

The Model 320 can optionally indicate stack temperature (Model 320T; 0-1800°F or 0-1000°C) for doing fuel efficiency calculations. The temperature sensor is built into the sampling probe. Efficiency charts for each fuel are provided.
