型 号： SD-660N   固定式χ、γ辐射报警仪
      产 地： 国  产

     SD660N固定式χ、γ辐射报警仪（在线χ、γ辐射剂量、剂量率报警仪）由探头、主机两大部分组成。是根究国家环保部门要求于06年针对医疗卫生机构设计推出的一种新型的室内射线监测仪器。它具有功能全，操作简便，可根据使用场所的所在位置和辐射强度任意设置剂量和剂量率报警阈值。仪器采用单位 μSv/h 或μSv直接显示。一台主机带1只探头并同时显示检测值，仪器有声光报警，以警示现场工作人员，确保工作人员安全。其它说明：直接使用交流220V给主机提供电源，对监测点进行实时剂量率/累计剂量监测和报警。实时剂量率/累计剂量监测值同时显示在主机面板上，实时剂量率/累计剂量的“报警阈值”储存在主机内EEPROM中。实时剂量率/累计剂量的“报警阈值”可通过面板上的按键进行修改。
主要用于放射治疗、工业 χ（γ）探伤、辐照加工以及其它χ（γ）射线场所辐射监测和报警，是防止被射线以外照射的有力武器。

(5)主机“辐射”报警音量可调，但不可完全关闭(主机故障报警音量不可调)
(6)主机故障/探测器故障/探测器连线故障/声光报警装置灯泡损坏/声光报警装置连线故障/报警(该类报警只有主机报警且音量不可调)
(7)对于高噪音工作环境下的工业探伤、辐照加工以及强辐射场还可选配两个外置式大功率专用声光报警装置，一个安放于辐射场内，另一个安放在控制室内，与主机同步报警，对防止被误照射更有效。

 Model: SD-660N fixed χ, γ Radiation Alarm
 Origin: Domestic

     SD660N fixed χ, γ radiation Alarm (on-line χ, γ radiation dose, dose rate alarm instrument) from the probe, the host of two main parts. Is a final request by the State Environmental Protection Department in 2006 for medical and health institutions designed to introduce a new type of indoor radiation monitoring instruments. It has full-featured, easy to operate, according to the use of premises location and intensity of an arbitrary set of radiation dose and dose rate alarm threshold. Instruments used unit μSv / h or μSv directly display. A host with a probe at the same time show the value of testing, apparatus, sound and light alarm to alert on-site staff, ensuring staff safety. Other Description: AC 220V directly to the host to provide power to the monitoring sites in real-time dose rate / total dose monitoring and alarm. Real-time dose rate / total dose monitoring values displayed simultaneously on the host panel, real-time dose rate / total dose of "alarm threshold" is stored in EEPROM within the host. Real-time dose rate / cumulative dose of "alarm threshold" on the front panel buttons can be modified.
Is mainly used for radiation therapy, industrial χ (γ) detection, radiation processing, and other χ (γ)-ray radiation monitoring and warning areas is to prevent outside radiation exposure was a powerful weapon.

Features
(1) Detection of components: use of G-M counter tube, high sensitivity, fast response, stable and reliable.
(2) Using ultra-high brightness LED also shows real-time dose rate and cumulative dose dose.
(3) Super-threshold dose rate alarms
(4) The cumulative dose of super-threshold alarm
(5) The host "radiation" alarm volume adjustable, but not completely shut down (host failure alarm volume is not adjustable)
(6) Host fault / failure detector / detector connection failure / damage to sound and light alarm lamp / sound and light alarm device connection fault / alarm (type of alarm is not only a master alarm and the volume adjustable)
(7) For high-noise working environment for industrial flaw detection, radiation processing, and strong radiation field can also be matching two external high-power-specific sound and light alarm device, a floor placed on the radiation, and the other placed in the control room, synchronization with the host alarm, to prevent them from being mistaken radiation more effective.
