乙炔，分子式C2H2，俗称风煤和电石气，是炔烃化合物系列中体积较小的一员，主要作工业用途，特别是烧焊金属方面。乙炔在室温下是一种无色、极易燃的气体。
针对乙炔这种特殊可燃性气体，我公司配置了专用固定式乙炔气体泄漏浓度检测(探测)报警器，不采用通用异丁烷进行标定，而是采用乙炔气体进行标定，检测更准确，针对性更强，性价比更高。
Acetylene Alarm
Summary on Acetylene Alarm
Acetylene, C2H2, commonly known as, wind coal, more little Molecular mass of Alkyne compounds, mainly used in industry, special in welding metal.
Acetylene at room temperature, is a colorless, more flammable gas. As for acetylene, the special alarm is launched, calibrated directly by acetylene instead of isobutene, getting the More accurate detection, More pertinent, and higher performance-price.
Acetylene alarm consists of gas detector an gas controller. The detector with imported high precision sensor as core part, monitoring in real time the concentration of acetylene, sending signals to the controller at the same time. The controller displays the concentration, sends audible & visual alarm once the concentration over the safe value.
Feature of Acetylene 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.
