氣體檢測報警器JN20
Gas Detection Alarm JN20
JN型氣體檢測報警器采用優(yōu)質(zhì)進口傳感器及芯片,先進的16位ADC數(shù)模轉(zhuǎn)換信號采集技術(shù),檢測精度最高響應(yīng)至PPm級別:具備自動零點校正,溫度補償,量程切換,免工具拆裝維護功能;表面磨砂工藝噴涂,外觀精致小巧防水、耐腐蝕。同時采用先進的OLED有機發(fā)光顯示,無需背光,觀察角度廣,壽命可達3-5年。
?4-20mA信號輸出,內(nèi)設(shè)2組繼電器報警開關(guān)量輸出功能,可實現(xiàn)在任何一級、二級開關(guān)量輸出模式中,選擇大于或小于設(shè)定值報警功能;可外接防爆型聲光報警器,超過報警點能實現(xiàn)聲音報警和光報警的警示作用。能精確測量有毒氣體濃度,并且根據(jù)預(yù)設(shè)的報警設(shè)定值進行報警。
JN type gas detection alarm adopts high-quality imported sensors and chips, advanced 16-bit ADC digital-to-analog conversion signal acquisition technology, and the highest detection accuracy responds to PPm level: it has the functions of automatic zero point correction, temperature compensation, range switching, tool-free disassembly and maintenance, and the surface is frosted and sprayed, and the appearance is exquisite, small, waterproof, and corrosion-resistant. At the same time, it adopts advanced OLED organic light-emitting display, no backlight, wide observation angle, and life span of up to 3-5 years.
? 4-20mA signal output, with 2 groups of relay alarm switching output function, which can realize the alarm function of greater than or less than the set value in any first-level and second-level switching output mode; It can accurately measure the concentration of toxic gases and give alarms according to the preset alarm setting value.
