产品简介
----------------------------------------------------------------------
通用天然气气体泄漏浓度检测探测报警器(Natural Gas Alarm)，简称天然气检测器，或天然气探测器，或天然气报警器，主要针对天然气（即甲烷）气体泄漏浓度检测、浓度显示及浓度超标后的声光报警提醒，并可联动然气电磁阀，一旦泄露，及时切断。
目前，国家对天然气气体泄漏检测报警器要求严格，厂家必须具有*，并且机器上贴有3C标签及消防标签，天然气气体报警器由气体探测器(Gas Detector)和气体报警控制器(Gas Controller)，气体报警控制器必须配置备电。
气体简介：天然气主要组成部分为甲烷（85%）和少量的乙烷、丙烷等气体。也有人称为“沼气”。我们这里主要是说天然气管道的天燃气。天然气的检测量程为0-LEL。天然气比空气轻，所以天然气探测器的安装位置在泄漏源的上方。
天然气气体报警器使用比较多的场所：加气站、酒店厨房、学校餐厅等存在天然气气体的场所。
天然气气体报警器产品特点：
◆ 测量准确：传感器采用进口气体敏感元件，精度高，零点漂移小，抗中毒性能好。
◆ 防爆设计：可用于工厂条件的1、2区危险场合。
◆ 维修方便：传感器采用数字化模组设计，现场更换时无需校零、标定。
◆ 声光报警：气体探测器可选配专用的防爆声光报警器，实现现场声光报警。
◆ 浓度显示：气体探测器可选配液晶浓度显示，现场实时显示浓度。

Natural Gas Alarm
Natural gas alarm mainly detects natural gas (i.e. methane), detects and displays mainly the concentration of natural gas, sending audible and visual alarm when the concentration exceeding the scheduled standard. Linking together with gas solenoid valve, cut off gas supply immediately once leakage occurs.
The state is strict in gas alarm at present, the factory must own 3C authentication. All equipment must stick 3C label & Explosion-proof label. Natural gas alarm is consists of detector and alarm control, the last must configure power reservation.
Natural gas alarm is used in more sites, such as gas station, kitchen, canteen and so on, in which gas exists.
product features
Accurate measurement: sensor with imported gas sensory unit, high precision, little zero shift, good anti-poisoning.
Explosion-proof design: suitable for 1 and 2 dangerous areas in factories.
Maintenance-free: the imported digital module in sensor easily removed for field replacement, no zero setting, no calibration.
Audible and visual alarm: realize audible and visual alarm on spot, if combined special Explosion-proof aural and visual alarm
Concentration display: real-time display concentration on spot, if LCD selected.
