1. Sensing resistance in air R
0
is measured under controlled ambient conditions, i.e. synthetic air at 23
?5?C and 50 ? 10% RH. Sampling test.
2. Sensitivity factor is defined as Rs at 0.25 ppm NO
2
, divided by R
S
in air. Test conditions are 23 ? 5?C
and ≤5% RH. Indicative values only. Sampling test.
IMPORTANT PRECAUTIONS:
Read the following instructions carefully before using the MiCS-2714 described here to avoid erroneous
readings and to prevent the device from permanent damage.
? The sensor must be reflow soldered in a neutral atmosphere, without soldering flux vapours.
? The sensor must not be exposed to high concentrations of organic solvents, silicone vapours or
cigarette-smoke in order to avoid poisoning the sensitive layer.
? Heater voltage above the specified maximum rating will destroy the sensor due to overheating.
? This sensor is to be placed in a filtered package that protects it against water and dust projections.
? SGX sensortech strongly recommends using ESD protection equipment to handle the sensor.

重要的预防措施:
在使用此处描述的MiCS-2714之前，请仔细阅读以下说明，以避免错误的
读数，并防止设备的yong久性损坏。
?传感器必须在中性气氛中回流焊接，无助焊剂蒸汽。
?传感器不能暴露在高浓度的有机溶剂、硅蒸气或
香烟烟雾，以避免中毒的敏感层。
?加热器电压超过规定的zui大额定值将由于过热而损坏传感器。
?该传感器被放置在一个过滤包中，以防止水和灰尘的喷射。
?SGX sensortech强烈建议使用静电防护设备来处理传感器。
