Wide ranges of models are provided for users’ convenience in the selection of the most suitable sensors for their applications from the vie points of target gases, detection purposes, operating conditions, and required accuracy. Generally speaking, catalytic type gas sensors are the best for flammable gases. Semiconductor type sensors and electrochemical cells would be good for detection of toxic gases and contamination gases contained in air. And thermally conductive type sensors would be suited for inert gas detection. However, the suitable sensor may differ depending on target gas concentrations to be detected. Our suggestions and recommendations will be given upon request.The features and characteristics of each sensor will be described later in this brochure, but rough ideas are shown below for the selection of a suitable sensor depending on the kinds and concentrations of target gases. Users who are going to use our sensor for the detection of a gas concentration near the border lines are recommended to contact us for technical assistance.

The main application is for gas detectors. Catalytic type sensors are much stable compared to semiconductortype gas sensors, and do not need any CPU for making detectors. Thus catalytic type gas sensors enable users to design flexible circuits for lower-cost gas detectors. The general features of Nemoto’s catalytic gas sensors are as below.1. Basic characteristics:* Good output linearity to gas concentrations up to LEL, especially excellentlinearity in the range below 50% of LEL.* Excellent repeatability of gas sensitivity. Variability within a day would beless than +/- 5%.* Speedy response. 90% response time of residential models is less than 20 sec.* Hardly affected by ambient temperature and humidity. No compensationcircuit is required for residential applications.* Least individual differences and simple calibration on detectors.* Short initial stabilization time.* Less affected by supply voltage variation. Stabilized supply voltage is notneeded.2. Durability, Long-term stability* Excellent stability under 60o C.* Durable under high temperature and humidity (50o C, 95% RH).* Not affected by long-term storage under high temperature and humidity (50o C,95% RH).* Resistive against vibration and impact.* Durable against corrosive gases such as hydrogen sulfide.* Durable against silicone gases (HMDS 10ppm).* Acceleration tests have proved a long life more than 10 years.3. Usage* Not like semiconductor type sensors, a long preparatory aging time is notnecessary for performance stabilization.* In case of gas detector applications, aging for 10 minutes would be enoughbefore calibration. Calibration can be done in air without a test gas.* Variation of ambient temperature & humidity or existence of noise gases doesnot affect to the characteristics of Nemoto sensors. It is not needed to createspecial ambient conditions for calibration.4. Applications* Gas leakage detectors* Incomplete combustion alarms* For water heaters* Alcohol checkers, Gas densitometers* For gasoline feeders深圳市深国安电子科技有限公司地址：广东省深圳市龙华新区牛栏前大厦Ｃ５０７ 蒋小姐：１３４　２８７６　２６３１ 电话：８６　７５５－８５２５８９００网址：ｗｗｗ．ｓｉｎｇｏａｎ．ｃｏｍ ｗｗｗ．ｓｉｎｇｏａｎ．ｃｏｍ．ｃｎ ｗｗｗ．ｓｈｅｎｇｕｏａｎ．ｃｏｍElectrochemical type gas sensorsThis is one of our main products in addition to the Hot-wire type sensors.Because of the limitation of its detection method, detectable gases are limitedsuch as toxic gases and incompletely combusted flue gases etc., howeverelectrochemical sensors show far superior accuracy and gas selectivitycompared to semiconductor type sensors. It was said that electrochemicaltype sensors had a problem of a shorter life, but Nemoto electrochemicalsensors are uniquely designed in the electrodes to have excellent accuracy andconsistency so that these sensors can be applied for maintenance-freeresidential detectors. Nemoto electrochemical sensors have also an innovativestructure to have realized the smallest size in the world. This small size givesflexibility in the component positioning when detectors are designed. Thereare two series of Nemoto electrochemical sensors, i.e. the 5 series for generaluse and the 7 series mainly used for industrial applications. The 5 seriesincludes a special type which electrode pins can be directly soldered with PCBs.The superior features are described below.1.Basic features:•The output signal is linear in the practical detection range of various target gases.•The excellent repeatability of gas sensitivity. Output signals fall into a range of ± 2% or less.•The faster response time. Electrochemical sensors generally do not have a quick response time, but Nemoto electrochemical sensors show a relatively quick responsecharacteristic. 90% response time is within 30 seconds.* When a simple temperature compensation circuit is added for the range of 20o C ∼ 50o C,the accuracy falls into ± 10% tolerance. Nemoto electrochemical sensors are hardlyaffected by humidity.•The individual differences are so small that alarm concentration can be adjusted by a uniformed calibration.•Initial output is stabilized in a short time after energized.2. Durability and long term stability•Detection accuracy is unchanged after use for 5,000 hours under 60o C and 90%RH.•Gas sensitivity is unchanged after use for 5,000 hours under 60o C and 15%RH.•Excellent resistivity to vibrations and shocks that are expected in common environment.•The sensors are not affected by silicon gases at all.• 5 year life is guaranteed for the standard type NAP-505.3. Usage•Different form semiconductor type sensors, Nemoto electrochemical sensors do not need preparatory aging at all.•In case of use for residential detectors, calibration is not required because the individual differences are negligible.•False-alarm-free because of no response to noise gases.•Battery operation is possible because the sensors do not have a heater.4. Applications•For incomplete combustion detectors, CO detectors, toxic gas detectors.•For combustion controllers for stoking equipment, monitors for indoor environment.•Various gas densitometers, measuring equipment.深圳市深国安电子科技有限公司地址：广东省深圳市龙华新区牛栏前大厦Ｃ５０７ 蒋小姐：１３４　２８７６　２６３１ 电话：８６　７５５－８５２５８９００网址：ｗｗｗ．ｓｉｎｇｏａｎ．ｃｏｍ ｗｗｗ．ｓｉｎｇｏａｎ．ｃｏｍ．ｃｎ ｗｗｗ．ｓｈｅｎｇｕｏａｎ．ｃｏｍNAP-2ANAP-2A is a universal type of sensor for flammable gases and can be used for gas detectors as well as for gas densitometers.

More specifically, the output shifts towards (+) side when the target gas has a larger molecular weight than the air, and shifts towards (-) side in case of a smaller molecular weight. The output characteristic of this sensor shows excellent linearity to the gas concentrations that is good enough to measure concentrations up to 100%. However, this sensor is humidity-dependent (As “humidity is “steam” which makes the output shift towards (-) side.), a compensation circuit would be needed upon designing circuits. Because of these characteristics, this sensor is suitable for CO2 gas measurement & CO2 gas monitoring in containers for vegetables & fruits etc.。

Measurement of output voltages ;Output voltages are to be measured with an electrometer having an impedance of 1014 or greater, or with an exclusively designed measuring circuit using an IC for smoke detectors.Usual testers with an impedance of around 100M may not be adequate for accuratemeasurements.2. Contamination with a flux ;Upon assembling of NIS-05A onto your smoke detectors, please pay attention that a soldering flux would not get inside the chamber. Washing or cleaning up should be required if the inside of the chamber is contaminated with a flux.3. Connection of output lead wire ;The lead wire of NIS-05A should be connected in air with the input terminal of your circuit, or the connected point should be supported with a teflon post so that the connected point would not touch to your PCB. Accurate output voltages can not be measured if the current leaks onto the PCB.4. Moisture protection ;The connection point of the output wire of NIS-05A and an input terminal of an IC or an FET should be protected with a silicone resin or the like. Current leakage under highly humid conditions would be minimized.;shielding5. ElectricalBecause of a sensor of a tiny current, NIS-05A is easily affected by electrical noises from the outside. It is therefore recommended to shield the sensor, especially the connection point must be electrically shielded.Packing1,000 pieces packed in an export carton.Dimensions ; 435(D) x 490(W) x 275(H) mmGross weight ; 14.5 Kgs.深圳市深国安电子科技有限公司12 Drawings。

因为极小的电流功耗，所以此传感器普遍应用于带电池驱动的烟雾探测器。

下面是关于NIS-05A特征的一些介绍。

1)特征;* 功耗极小，可用电池驱动使用几年.* 结构简单，比光电式烟雾传感器更便宜.* 输出不依赖于烟雾的颜色.* 和光电式烟雾传感器相比，耐用性更好.* 放射能很小2) 应用范围;*火灾报警器 * 空气清洁器 * 烟尘计数器3) 最大额定值;* 供给电压 DC 24V* 操作环境中的温湿度 温度 -20 ∼ +70o C湿度 小于95% RH* 储藏环境中的温湿度 温度 -25 ∼ +80o C湿度 小于95% RH4) 推荐额定值;* 供给电压 DC 9V* 电流功耗 15 +/- 2 pA (9V电压供应)* 空气中输出 5.5 +/-0.5 V (25o C, 60% RH) * 烟雾敏感度 1.2 +/- 0.3 V (2%/英尺,依据UL217)* 操作环境中的温湿度 温度 -10 ∼ +60o C湿度 小于95% RH*储藏环境中的温湿度 温度 -10 ∼ +70o C湿度 小于95% RH5) 结构, 尺寸 & 重量* 结构 如下页图纸所示.* 尺寸 如下页图纸所示.* 重量 约13.7克下面是NIS－05A的结构Fig. 1 NIS－05A结构放射性同位元素（图中C）是阿尔法射线放射源镅241，其放射量非常小只有18.5KBq.由于放射源已被不锈钢完全密封（图中G所示），所以放射能不会泄漏到周围环境中。

放射性同位元素本身也有被镀金密封以防止受有机溶脂及碳酸物的腐蚀。

另外封口处也有耐溶性，所以当有必要的时候传感器也可以用有机溶脂清洗。
