air calibration（空氣校準(zhǔn)）：
the high-accuracy and fast response of this model is only surpassed by its ability to calibrate without the assistance of support gases. the micro-fuel cell produces and output that is linear and enables the use of ambient air for calibration. the model also accommodates the use of a certified ppm o2 span or zero gas which speeds calibration when necessary and confirms the system is leak free.（該型號(hào)的高精度和快速響應(yīng)是超越它的校準(zhǔn)能力，沒(méi)有輔助氣體的協(xié)助。微型燃料電池的生產(chǎn)和輸出是線性的，并能夠使用環(huán)境空氣進(jìn)行校準(zhǔn)。該型號(hào)還適用于使用經(jīng)過(guò)認(rèn)證的ppm o2跨度或零氣體，在必要時(shí)加速校準(zhǔn)，并確認(rèn)系統(tǒng)無(wú)泄漏。）
user-configurable ranges（用戶(hù)可配置的范圍）：
three user-configurable ranges are come standard with this model. when changing ranges, you are provided with excellent linearity of analysis precluding recalibration. two programmable concentration alarms will provide the versatility to satisfy nearly any requirement.（三個(gè)用戶(hù)可配置的范圍是標(biāo)準(zhǔn)與此模型。當(dāng)改變量程時(shí)，您可以獲得線性分析，避免重新校準(zhǔn)。兩個(gè)可編程濃度報(bào)警器將提供通用性，以滿(mǎn)足幾乎任何要求。）

maintenance-free免維護(hù)：
the model uses a specifically qualified fast recovery instatrace micro-fuel cell to measure trace levels of o2 in the sample gas. this sensor sets industry standards for accuracy, sensitivity and ease of use. the instatrace is a sealed electrochemical device with no electrolyte to charge or electrodes to clean, making it maintenance-free.（該模型使用了instatrace微型燃料電池(instatrace micro-fuel cell)來(lái)測(cè)量樣品氣體中痕量的o2。該傳感器為精度、靈敏度和易用性設(shè)定了行業(yè)標(biāo)準(zhǔn)。instatrace是一種密封的電化學(xué)設(shè)備，不需要充電電解液，也不需要清潔電極，因此無(wú)需維護(hù)。）
convenient outputs輸出便利：
