Product Overview
The SFD-Ex-SHAN-6 Portable Multi-functional Composite Gas Detector is an intelligent 6-in-1 gas detection device independently developed and produced, featuring high sensitivity and operational reliability. Configured with diverse sensors, it can accurately detect the concentration of more than 100 types of flammable and toxic gases in the ambient environment. The device supports wireless alarm signal transmission to realize synchronous alarm linkage with all devices of the same series. It intuitively displays the alarm device number, primary and secondary alarm levels, and provides audio alerts, voice prompts and one-click SOS alarm, which can be synchronously pushed to surrounding equipment.
The pump-sampling version is capable of monitoring air inlet pressure and pinpointing gas leakage points through gas concentration voice prompts. The detector supports event logging with unlimited storage capacity (subject to memory card space), covering power-on/off records, alarm time, gas types and other key parameters, all of which will not be lost after power outage. Detection and alarm data can be queried via the local device, computer web page and mobile APP, and stored in local equipment and servers in chart form for convenient inquiry and backup.
Equipped with a position upload function, the device supports real-time positioning and historical trajectory viewing via servers and client terminals. It also realizes two-way video intercom between mobile terminals, computers and on-site detection devices. Adopting a low-power processor and built-in high-capacity lithium polymer battery, matched with a professional smart charger and comprehensive protection circuits, the detector features ultra-long standby time and high safety performance. (Note: The battery enjoys a 1-year warranty. Replacement is recommended after the warranty period. Failures caused by expired batteries or artificially damaged batteries are not covered by the warranty.)
Lightweight and compact, the detector is easy to carry and operate. It delivers accurate measurement results, stable readings and clear display. All parameter settings and alarm records are permanently saved even after power failure, and the setting menu is protected by passwords to ensure data security. Customized patterns for the air pump appearance are available to meet personalized customer needs.
With wireless alarm transceiving function, multiple devices can form a networked monitoring system to timely transmit on-site alarm information, effectively avoiding the occurrence of secondary disasters.
Product Features
Equipped with imported sensors, this detector can monitor six types of gases at the same time. It adopts a full-color TFT LCD screen for sharp and legible readouts. It supports intelligent temperature compensation and fault prompt alarms. The built-in wireless relay enables synchronous alarms among devices within the same area. It integrates multiple additional functions including intercom, video recording, photo capture, positioning, patrol inspection, flashlight, gas leak detection and pressure measurement. Pump-sampling or diffusion detection modes are available as options. The product has obtained national explosion-proof certification.
