详细内容
主要特点: 1、报警阈值可调 2、具有测个人剂量与辐射剂量率两种功能 3、数据存贮量大,具有1500小时的数据存贮能力。 4、阈值报警连续可调,具有累积剂量、剂量率、阻塞、超时等阈值报警功能 5、自动记录各种数据、断电或更换电池数据不丢失 6、可显示、累积剂量、剂量率、工作时间、剂量率发生时刻及大小、累积剂量阈值、剂量率阈值等参数 7、灵敏度高,对环境本底也有响应 8、体积小、操作简单 9、抗电磁干扰能力强 技术指标: (1) 探测器:GM计数管(经补偿) (2)显示:4位LCD可显示累积剂量、剂量率、阈值、剂量率及发生时刻、时钟等 (3)测量范围: 剂量当量率:Hp(10)0.1 μSv/h-99.99 mSv/h 累积剂量当量:Hp(10)0.0 μSv-9999 mSv (4)固有误差:<10%(2 mSv/h左右) (5)剂量当量率响应:≤±20%(测量范围内) (6)能量响应:≤±30% 50keV- 1.3MeV (7)测量时间:3600秒—1秒 自动切换 (8)内存:64K 内存可存贮大约一周的数据,不带通信接口 (9)报警功能:大于设定的累积剂量或剂量率阈值时有声光报警,并有符号显示阻塞报警,当计数管阻塞时,连续报警不停,并有符号显示报警声音强度在30cm处约80dB (10)欠压指示:电池电压<1.3±0.05V,仪器显示电池欠压符号 (11)电源功耗:AAA型1.5V碱性电池一节(5号电池)环境本底下连续使用720小时 (12)温度特性:≤±10% -10℃—+50℃ (13)湿度特性:≤±10% 0—95%RH(+35℃) (14)外形尺寸:55(宽)×75(长)×20(厚)(mm) (21)重量:<98克 The battery operated monitor LH-III measuresχ、γ photon radiation personal dose by an internal high sensitive GM tube detector. As a survey meter, it automatically measures and records the radiation dose by means of per-set address coding and historical dose accumulation time. Dose alarm threshold and accumulated dose alarm threshold can be set by users to decrease the occupational dose intake by means of alarm, at any time, if any threshold had been exceeded. The radiation monitor is a rugged small size light weight instrument which is suitable for applications of routine survey and emergency response in the nuclear facilities, radiation scientific research institutes and environmental supervision agencies. Technical performance: l Energy range:28keV~1.3 MeV l Dose rate measurement range:0.1μSv~10 mSv l Accumulated dose measurement range:0~10 Sv l Measurement accuracy: ≤±10% (137CS, 1mSv/h) l Alarm sound intensity: > 80 dB(distance 50cm) l Dynamic display of measurement uncertainty l button activated LCD illumination l Infrared data transmission l Overall dimension:80×140×37 mm l LCD display size: 35×54 mm l Environment temperature: -10℃~+50℃ l Environment humidity: ≤95%(+40℃) l Battery duty life: >700h (by one AA size alkaline batteries) l Weight: approx.98g |
