美國MOCON頂空分析儀測試原理: 二氧化碳 當(dāng)氣體通過一個(gè)內(nèi)置傳感器時(shí),利用紅外能源,紅外過濾器和溫差電堆檢波器來感應(yīng)通過的氣體。溫差電堆是一個(gè)電壓發(fā)生器,可以輸出表明CO2水平的電信號(hào)。 氧氣 氧氣測量子系統(tǒng)的基礎(chǔ)是一種固態(tài)的氧離子傳導(dǎo)材料——鋯氧化物。根據(jù)該材料的陶瓷點(diǎn)陣結(jié)構(gòu)內(nèi)的氧氣空位,氧離子可以在一個(gè)升高的溫度下進(jìn)入固體材料里。這種特性可以測量未知組成的氣體中的氧含量。 美國MOCON頂空分析儀用途: 測試包裝內(nèi)氧氣、二氧化碳、氧氣和二氧化碳的混合氣體的百分含量。 美國MOCON頂空分析儀特點(diǎn): 美國MOCON頂空分析儀常規(guī)應(yīng)用: 型號(hào) 450 550 650 樣品量 5cc (automatic mode) 2 cc (manual mode) 5 cc (automatic mode) 2 cc (manual mode) 8 cc (automatic mode) 5 cc (mode) 精度 ±0.05% O2 - 0.1% to 9.99% ± 1%O2 - 10.0% to Carbon Dioxide ± 2% of full scale ±0.05% O2 - 0.1% to 9.99% ±1% O2 - 10.0% to Carbon Dioxide ±2% of full scale 測試范圍 Oxygen –0 ppm to Carbon Dioxide – 0% to Oxygen – 0 ppm to Carbon Dioxide – 0% to 響應(yīng)時(shí)間 98% of final value within 5 seconds 98% of final value within 5 seconds 98% of final value within 5 seconds 零點(diǎn)漂移 ± 0.5% of full scale per 24 hours at room air ± 0.5% of full scale per 24 hours at room air ± 0.5% of full scale per 24 hours at room air 預(yù)熱時(shí)間 30 minutes 30 minutes 30 minutes 分辨率 Oxygen: 1 ppm in range 1 to 999 ppm .001% in range . to .999% 0.01% in range 1.00% to 9.99% 00.1% in range 10.0% to 99.9% Carbon Dioxide: 0.1% in range 0% to 99.9% Oxygen 1 ppm in range 1 to 999 ppm .001% in range . to .999% 0.01% in range 1.00% to 9.99% 00.1% in range 10.0% to 99.9% Carbon Dioxide 0.1% in range 0% to 99.9% 測試 方法 Oxygen Solid Carbon Dioxide NDIR (Non Dispersive Infrared) Oxygen Solid State Zirconium Oxide Carbon Dioxide NDIR (Non Dispersive Infrared) 取樣方法 自動(dòng)或手動(dòng) 用注射器(選項(xiàng)) 注入樣品 自動(dòng)或手動(dòng) 用注射器(選項(xiàng))注入樣品 自動(dòng)或手動(dòng) 用注射器(選項(xiàng))注入樣品 顯示 三位,綠色 LED 三位,綠色LED 三位,綠色LED 尺寸、重量 20” x 18” x 13” dimensional weight 25 pounds 20” x 18” x 13” dimensional weight 25 pounds 20” x 18” x 13” dimensional weight 25 pounds 操作環(huán)境溫度 5C to 40C (Factory certified at 23C±4C) 5C to 40C (Factory certified at 23C±4C) 5C to 40C (Factory certified at 23C±4C) 操作環(huán)境濕度 10 to 90% non-condensing 10 to 90% non-condensing 10 to 90% non-condensing 電壓 120 VAV, 240 VAC (other voltages available) 120 VAV, 240 VAC (other voltages available) 120 VAV, 240 VAC (other voltages available) 電源頻率 50/60 Hz 50/60 Hz 50/60 Hz
