Product Overview
The SFD-Ex-MOV-S Mobile Multi-Gas Detector is a high-sensitivity and high-reliability intelligent 4-in-1 detection device independently developed and produced. By configuring different sensors, it can accurately detect the concentration of more than 100 types of flammable and toxic gases in the working environment.
The device supports wireless alarm signal transmission and achieves synchronous alarm linkage with all products of the same series. It intuitively displays the alarm device number, primary and secondary alarm status, and is equipped with audible alarm prompts for timely risk reminder.
The detector has a powerful event recording function, which can store up to 1999 records including equipment power-on and power-off events. Key information such as alarm time and gas type is completely retained without loss even after power failure.
Adopting a built-in high-capacity lithium polymer battery, matched with a professional smart charger and complete protection circuits, the device features long working hours and high operational safety and stability.
With accurate measurement performance, clear visual display and stable detection values, the detector adopts a humanized panel layout and simple operation logic. Parameter configuration is efficient and convenient. All setting parameters and alarm records are permanently saved after power failure, and the setting menu is protected by password to ensure equipment operation safety.
Devices realize mutual alarm information transceiving through wireless signals, forming a complete networked monitoring system. It can quickly feedback on-site abnormal conditions, effectively avoiding the occurrence of secondary safety disasters.
Product Features
It adopts imported sensors to detect four types of gases simultaneously. Equipped with a full-color OLED screen, it delivers sharp and clear readings.
The detector supports intelligent temperature compensation and fault alarm indication. It has a wireless retransmission function to realize synchronous alarms among devices in the same area.
Powered by a rechargeable lithium battery, it is lightweight and easy to carry. Pump-sampling accessories are available as an option.
This product has obtained national explosion-proof certification.
