丙酮是一种无色透明液体，易挥发，浓度一旦超标，便有爆炸危险，因此在丙酮存在的化工场所可以配置丙酮气体报警器，实时监测丙酮气体浓度，一旦浓度超标，及时发出声光报警提醒。
丙酮气体报警器主要由气体探测器和气体报警控制器组成，气体探测器，防爆，安装在丙酮存在的现场，实时检测浓度；气体报警控制器安装在值班室、休息室，方便观察的地方，两者通过线缆实现连接，控制器实时显示气体浓度，并且浓度超标后声光报警，可联动外接设备。
丙酮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。
◆
防爆型设计：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。

Acetone Gas Alarm
Acetone, a colorless transparent liquid, volatile. There is a danger of explosion, when the concentration of acetone gas in the air exceeding the safe value. Acetone gas alarm may be installed in the site in which acetone exists, to monitor in real time the concentration of acetone gas, to send audible and visual alarm, once the concentration of acetone gas in the air exceeding the safe value.
Acetone gas alarm consists of gas detector an gas controller. The detector, explosion-proof, installed in the site, monitoring in real time the concentration of acetone gas. The controller installed in duty room, rest room, or other place that is easy to observe, connected the detector with cable, displaying in real time the gas concentration, sends audible & visual alarm once the concentration over the safe value, and starts the linkage devices.
Product feature
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.
