EM-21/CO2 Carbon Dioxide Analyzer (English)
The EM-21/CO2 is a portable infrared CO2 gas detector utilizing dual-beam IR measurement technology for precise environmental monitoring. With a detection range of 0-50,000ppm and 1ppm resolution, it reliably measures carbon dioxide levels in diverse settings including industrial plants, greenhouses, and public venues. The compact design (113×60×24mm) incorporates a rechargeable battery providing 10 hours of continuous operation. Its NDIR sensor detects CO2-specific infrared absorption without cross-sensitivity to other gases, ensuring measurement accuracy. The instrument features real-time digital display with audible/visual alarms when concentrations exceed user-defined thresholds. The rugged housing provides shock resistance and splash protection for field applications. Simple one-button operation and minimal maintenance requirements make it suitable for routine air quality assessments in energy facilities, agricultural sites, and commercial buildings. The analyzer automatically compensates for temperature variations to maintain consistent performance across operating conditions.281927
技術(shù)特點(diǎn)補(bǔ)充說(shuō)明
該產(chǎn)品采用擴(kuò)散式采樣方式，響應(yīng)時(shí)間約60秒，測(cè)量精度為讀數(shù)的±5%±0.01%CO2。儀器內(nèi)部集成溫度補(bǔ)償模塊，可在-5~40℃環(huán)境下穩(wěn)定工作。人性化設(shè)計(jì)包括背光顯示功能，便于昏暗環(huán)境讀數(shù)，同時(shí)配備數(shù)據(jù)存儲(chǔ)功能記錄監(jiān)測(cè)歷史。紅外傳感器壽命較長(zhǎng)，正常使用情況下可保持穩(wěn)定性能。適用于勞動(dòng)保護(hù)、環(huán)境監(jiān)測(cè)等場(chǎng)景，幫助用戶(hù)評(píng)估通風(fēng)效率或潛在健康風(fēng)險(xiǎn)。681927
Application Scenarios
This device serves multiple sectors: In HVAC systems, it verifies air exchange efficiency by tracking CO2 buildup; in agricultural facilities, it monitors greenhouse gas levels for crop optimization; industrial plants use it for confined space entry safety checks. The tool assists in identifying inadequate ventilation areas by detecting CO2 accumulation patterns, supporting occupational health management. Its portability allows for spot-check measurements or continuous monitoring through extended deployment.1619
