Overview
This SF6 and oxygen detector monitors SF6, O2, temperature and humidity in indoor electrical equipment rooms, alarming at set limits. It uses NDIR with auto-zero, includes a PIR sensor for personnel detection, logs history and alarms, uploads data via RS485 and lasts over 10 years.
Key Features
- Non-Dispersive Infrared (NDIR) technology
- Fast response time
- Accuracy guaranteed at full temperature and humidity range
- Automatic zero calibration function to overcome drift and false alarms
- PIR infrared monitoring function supports human body induction
- Historical data record, query and automatic alarm record
- Small size and compact structure for easy installation
- High reliability and long-life time (>10 years)
