● AEC220V power supply
This detector works while it is electrified (220V). The comprehensive cost is low. It has functions of controller + detector, as an independent system;
● Alarming mode
Audible-visual alarm: buzzer alarming and indicator alarming;
● Real-time concentration detection
Monitor combustible gases within the lower explosive limit in the industrial environment and give alarms;
● LED display
Adopting highly reliable LED digital display, it can monitor the concentration of combustible gases in the area in real-time;
● Sensors can be hot swapped and replaced
Greatly reducing maintenance costs in the later stage;
● Linked output
It has a set of optional output methods (switch quantity or level output);
● Wireless transmission
NB-IOT communication modules are optional, used to send data to MSSP wirelessly. User can monitor equipment running statuses through a fixed terminal or a mobile terminal APP;
● High sensitivity
Automatic zero correction (to avoid zero wander that may cause a measurement error), automatic curve compensation, intelligent temperature and zero compensation algorithm (for better performance), low power consumption, two-point calibration, curve-fitting technique, high accuracy, stable performance and reliable sensitivity;
● IR remote control
An IR remote controller is used to set parameters;
● Application sites
Mini-sized industrial and commercial gas application sites in the urban fuel gas field.
