丙酮是一種無色透明液體，易揮發(fā)，濃度一旦超標(biāo)，便有爆炸危險(xiǎn)，因此在丙酮存在的化工場所可以配置丙酮?dú)怏w報(bào)警器，實(shí)時(shí)監(jiān)測丙酮?dú)怏w濃度，一旦濃度超標(biāo)，及時(shí)發(fā)出聲光報(bào)警提醒。
丙酮?dú)怏w報(bào)警器主要由氣體探測器和氣體報(bào)警控制器組成，氣體探測器，防爆，安裝在丙酮存在的現(xiàn)場，實(shí)時(shí)檢測濃度；氣體報(bào)警控制器安裝在值班室、休息室，方便觀察的地方，兩者通過線纜實(shí)現(xiàn)連接，控制器實(shí)時(shí)顯示氣體濃度，并且濃度超標(biāo)后聲光報(bào)警，可聯(lián)動外接設(shè)備。
丙酮?dú)怏w報(bào)警器產(chǎn)品特點(diǎn)： ◆
測量準(zhǔn)確：傳感器采用進(jìn)口氣體敏感元件，精度高，零點(diǎn)漂移小，抗中毒性能好。
◆
防爆型設(shè)計(jì)：可用于工廠條件的1、2區(qū)危險(xiǎn)場合。
◆
維修方便：傳感器采用數(shù)字化模組設(shè)計(jì)，現(xiàn)場更換時(shí)無需校零、標(biāo)定。
◆
聲光報(bào)警：氣體探測器可選配專用的防爆聲光報(bào)警器，實(shí)現(xiàn)現(xiàn)場聲光報(bào)警。
◆
濃度顯示：氣體探測器可選配液晶濃度顯示，現(xiàn)場實(shí)時(shí)顯示濃度。

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.
