Model 311 Portable SO2 Ambient Analyzer (NOVA)
It then flows on into the sensor where the SO2 is detected and digitally displayed on an LCD meter. The meter may also be backlit for use in dark areas. A rechargeable battery provides enough power to 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 light on the front panel indicates when to recharge. A green LED light indicates that it is receiving charging power. A recharger is included.
