產(chǎn)品簡介
----------------------------------------------------------------------
瓦斯氣體探測報警器（Mashgas alarm）由瓦斯氣體探測器(Mashgas detector)和瓦斯氣體報警控制器(Mashgas Controller兩部分組成。氣體檢測，也稱氣體探測。氣體探測器實時檢測瓦斯?jié)舛龋瑲怏w報警控制器接收氣體探測器檢測的濃度，并顯示，濃度一旦超標可聲光報警提醒，并可聯(lián)動噴淋、排風等外接設(shè)備，或者上傳電腦、發(fā)送手機短信等，防止危險事故的發(fā)生。
瓦斯氣體報警器產(chǎn)品特點：
◆ 測量準確：傳感器采用進口氣體敏感元件，精度高，零點漂移小，抗中毒性能好。
◆ 防爆型設(shè)計：可用于工廠條件的1、2區(qū)危險場合。
◆ 維修方便：傳感器采用數(shù)字化模組設(shè)計，現(xiàn)場更換時無需校零、標定。
◆ 聲光報警：氣體探測器可選配專用的防爆聲光報警器，實現(xiàn)現(xiàn)場聲光報警。
◆ 濃度顯示：氣體探測器可選配液晶濃度顯示，現(xiàn)場實時顯示濃度。

Mashgas alarm
Mashgas alarm composed of gas detector and controller.The detector monitors in real time the concentration of methane. The controller receives the detection results from detector, and displays the concentration. The controller sends the audible & visual alarm once the concentration over the scheduled value, and starts the linkage devices (sprayer, fan, etc.), or uploads to PC, sends short messages to mobiles, avoiding the dangerous accidents.
Feature of Mashgas Alarm
1. Accurate measurement: sensor with imported gas sensory unit, high precision, less zero shift, strong anti-poisoning.
2. Explosion-proof design: suitable for 1-area and 2-area dangerous site in firm.
3. Maintenance-free: sensor designed with digital module group, no need to zero setting and calibration.
4. Audible and visual alarm: gas detector if equipped with explosion-proof audible and visual alarm, sending audible & visual alarm on the spot.
5. Concentration display: gas detector if equipped with LCD, displaying the concentration on the spot.
