    亲们购买时请注意一下几点哦!!!请先阅读完说明描述了解清楚再购买!!!

    近来发现有买家反映有些东西测试不出,根本没有辐射,甚至说我们的产品有问题,

    我们要说明一下,现在有些新出的产品,有的已经是有防辐射保护,或者有的是没有达到有危害的指标,安全范围内,或者很微弱,所以没有反应,比如(微波炉、苹果5手机)还就是带有三脚真实接地的电器有可能会出现没有反应,不是说所有电器都有反应哦,请释知,以免带来不必要的麻烦或者纠纷,介意者请不要拍,谢谢合作!

    此款是声、光报警不带显示,使用7号电池2节。

    测试小窍门:

    测试笔记本(台式)电脑的时候请先将电脑的电源插好电连接到电脑上面再测试,笔记本测试把测试笔靠近电源接口反应明显些,如果电脑插头连接到不接地的家用插座反应会更加明显

    辐射的原理
    辐射的原理是电流产生磁场,磁场产生电场 电场再产生磁场这样无限循环的,它的来源是电流,所以只要有电流就有辐射.

    以下是有些电器的检测不出的原因说明:

    有些液晶屏,笔记本电脑为啥检测不到辐射?
    因为笔记本电脑使用的是LCD显示屏是液晶屏的,液晶屏的发光不是靠电子束轰击荧光屏,没有普通显示器的高压线圈它的辐射很低。所以检测仪检测不到.传统显示器的显示材料是荧光粉,通过电子束撞击荧光粉而显示,电子束在打到荧光粉上的一刹那间会产?看蟮牡绱欧?.

    为啥有些电脑、电器、手机等检测不到辐射?
    1.有些厂家在产品设计时做有辐射屏蔽技术,2.有些电器本身带有自动消除辐射电子电路,释放辐射标准达到国家辐射安全标准.

    为啥检测C网手机的辐射很低或没有辐射数字?
    信息产业部广州移动通信产品质量监督检验中心对CDMA、GSM手机平均发射功率进行实地测试调查,发现CDMA手机的总平均发射功率比GSM手机低842倍.有关专家表示,目前国际上对手机发射功率与人体辐射之间是否有必然联系尚无定论,但可以肯定的是,发射功率是手机辐射的主要来源,在正常工作的情况下,手机的发射功率越小,手机的寿命越长、耗电越少。

    为啥电器有时能检测到有时检测不到?
    影响检测效果的原因有多方面1.电流:电源电流的强弱也会影响检测效果.2.气候:天气干燥时很容易产生静电,静电看不见又摸不着,附着于物体表面,在与其他物体互相作用时才会释放能量。 当人感觉到电击时,人身上的静电电压已超过2000伏;当看到放电火花时,身上的静电已经超过3000伏,这时手指会有针刺般的痛感;当听到放电的“劈啪”声音时,身上的静电已高达7000-8000伏。这样平时检测没有辐射的电器可能也会反应有辐射的。

    为啥检测不到真正接地线的电器?
    真正接地线的电器它的大部分的辐射已通过接地装置把辐射导入大地,所以电器的辐射值基本达到安全范围.

    当我们能检测家里的电源线或部分电器,而其它的电器或电脑检测不到的话,说明其它产品辐射已达到安全范围内。

    . 特性:
    感应非接触测试,该仪器不仅可用于可靠快速地测量家电、电脑所发出的电磁辐射,而且可以快速准确地测量手机辐射

    台式机与笔记本哪个辐射大,手机什么时候辐射超标,还有哪些靠近我们的物品辐射有危害,不用接触,一测便知)
    多功能电磁辐射检测仪:它是二合一的电磁辐射检测仪.能检测家用电器,也能同时检测手机电磁辐射

    多功能电磁辐射检测仪说明:
    1.仪器型号:AT-9
    2.规格尺寸:135×68×25mm
    3.测量范围:20Hz—2000MHz
    4.显示单位:μm/cm2(微瓦/平方厘米)
    5.测试误差:±10μw/cm2(微瓦/平方厘米)
    6.采样速率:约5次/秒
    7.使用温度:0—40℃
    8.使用湿度:小于70%RH
    9.报警方式:声、光报警
    10.数显范围:0-1999μw/cm2(微瓦/平方厘米),超出则显示为:1
    家用电器类低频辐射检测方法:打开电源开关,让仪器的前方正对着被测目标,如有辐射,检测仪声、光报警)或者显示屏上将显示出辐射值,并伴随有灯光和声音报警。因为电磁波是不断变化的.上面声、光报警)或者显示的数字也是在一定范围内不断变化的。检测防辐射产品或用手拿住防辐射卡放在仪器与被检测目标这之间,从声、光报警)或者显示屏数值的变化就可以看出防辐射产品的功效大小.

    测试范围:
    家庭居室、办公室、计算机房、控制室、高压线、计算机、电视机、复印机、传真机、电缆、蓝牙无线系统、监控器、空调和防辐射产品等较低频段电气设备电磁辐射和手机的高频电磁辐射的测试。

    注意事项:

    1.当不使用时请(拆出电池)或者关闭电源,以延长电池的使用时间.
    2.当测辐射仪
    声、光报警)或者显示屏上出现电量不足时。需立即更换电池(9V电池)。

    Pricing is subject to change without prior notice due to a number of potential factors including, but not limited to: increased material costs, changes in manufacturing costs, licensing fees, shipping and handling charges, and inflation.

    3. Customs and Tax

    Customs is a government agency, which is responsible for regulating shipments entering a country or region. All shipments being sent to and from a country or region must clear customs first. It's always buyer's responsibilities to clear customs and pay the relevant custom duties.

    MyTrustrade will assure that the goods clear China Customs, but we are not responsible for clearance in your country.

    If your shipment has been held by customs, you might need to pay taxes to get your parcel.

    In many countries, a parcel will be considered commercial if it weights over 10kg. Customs will block these parcels and ask you to pay duties. To prevent this, you should monitor the weight of your parcel.

    Having too many similar items in the same parcel will draw the Customs’ attention. You should not send large numbers of similar products together. Instead, separate them into different parcels.

    Custom sensitive items like counterfeits, cosmetics, liquid, cream, battery, harddisk, air-tight food, and etc. are likely to be inspected and confiscated by Custom and the shipping cycle could be delayed as a result. MyTrustrade will not be responsible for the loss of those items during custom inspection, or any consequence caused by purchasing such items.

    It is the buyer's responsibility for any custom duty fee that might be charged from delivery. How the import duty will be charged depends on each country's custom policies.
