As a Zone 2-Category 3 device, the PC3-6824 Nitrogen Dioxide gas detector is designed for continuously monitoring Nitrogen Dioxide in the light industrial areas.
High-quality catalytic sensor in PC3-6824 shows excellent results in 0-30ppm range.
• Sensor: Uses high-quality electrochemical sensor to detect Nitrogen Dioxide gas in 0-30ppm range.
• Connection: Provides universal output 4-20mA and Modbus RS485
• Entry: 1 x 1/2″ NPT cable entry
• Body: Aluminium die-cast body and sensor head superb performance under harsh environmental conditions with IP65 protection class.
• Remote Control: Detector status can be monitored through Prosense Gas Monitoring software remotely.
• Modbus: Easy to integrate into SCADA systems via open-source Modbus RS485(RTU) codes
• Relay Contacts: 2 Alarm, 1 Fault relays can be set predefined levels and they can manage the other devices like a siren, a beacon in case of any event.
