氣體檢測(cè)報(bào)警器JN20
Gas Detection Alarm JN20
JN型氣體檢測(cè)報(bào)警器采用優(yōu)質(zhì)進(jìn)口傳感器及芯片，先進(jìn)的16位ADC數(shù)模轉(zhuǎn)換信號(hào)采集技術(shù)，檢測(cè)精度最高響應(yīng)至PPm級(jí)別：具備自動(dòng)零點(diǎn)校正，溫度補(bǔ)償，量程切換，免工具拆裝維護(hù)功能；表面磨砂工藝噴涂，外觀精致小巧防水、耐腐蝕。同時(shí)采用先進(jìn)的OLED有機(jī)發(fā)光顯示，無需背光，觀察角度廣，壽命可達(dá)3-5年。
?4-20mA信號(hào)輸出，內(nèi)設(shè)2組繼電器報(bào)警開關(guān)量輸出功能，可實(shí)現(xiàn)在任何一級(jí)、二級(jí)開關(guān)量輸出模式中，選擇大于或小于設(shè)定值報(bào)警功能；可外接防爆型聲光報(bào)警器，超過報(bào)警點(diǎn)能實(shí)現(xiàn)聲音報(bào)警和光報(bào)警的警示作用。能精確測(cè)量有毒氣體濃度，并且根據(jù)預(yù)設(shè)的報(bào)警設(shè)定值進(jìn)行報(bào)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.
