放射性检测仪All models feature internal GM （Geiger-Mueller） detector for greater handling ease, anti-saturation circuitry ａnd red ｃount light. Audible beeper can be switched on or off. Built-in battery check, long battery life. Carrying case is included. 所有型号的特点（盖革缪勒）GM内部大的处理缓解探测器，抗饱和电路和红细胞的光。听到蜂鸣器可以开启或关闭。内置电池检测，电池寿命长。携带情况包括
Monitor 4—Meter detects alpha, beta, gamma, ａnd x-rays utilizing an uncompensated halogen-quenched GM tube with a 1.5–2.0mg/cm2 mica end window. Analog meter reads 0–0.5, 0–5, 0–50mR/hr. or 0–50,000cpm, in three settable 监控者检测α，β，γ，和利用无卤素GM管与1.5–2.0mg/cm2云母窗X射线。模拟仪表读取0–0.5，0–5，0–50mr /小时。0–50000cpm，可设定范围在三。听到蜂鸣器可以关闭ranges. Audible beeper can be turned off.
Monitor 4EC—The Monitor 4EC is the Monitor 4 with an energy compensated GM detector. 监视器监视器是监控4ec 4ec 4的能量补偿通用探测器
Typical efficiencies using 2[pi] geometry are:
Smallest detectable level of 125I is approx. 0.02µCi. Recommended detection levels for 125I is 0.5mCi ａnd up. Gamma sensitivity is 25cps/mR/hr. 125I小可检测水平约为0.02µ词。125I推荐的检测水平和静脉。γ灵敏度25cps /先生/小时。
MC1K—Detects gamma ａnd x-rays in four ranges up to 1000mR/hr. The energy compensated GM detector measures down to 30keV. Normal background is approximately 4cpm.mc1k检测γ和X射线在四范围可达1000mr /小时。能量补偿通用探测器测量了它。正常的背景是大约4cpm | Efficiency | 49% [source Sr-90 （0.0201 µCi）], 33% [source Tc-99 （0.043 µCi）], 21% [source C-14 （0.130 µCi）] | | Energy | 0.200–0.544 MeV [source Sr-90 （0.0201 µCi）], 0.085–0.295 MeV [source Tc-99 （0.043 µCi）], 0.049–0.151 MeV [source C-14 （0.130 µCi）] | | cpm | 22,000 [source Sr-90 （0.0201 µCi）], 14,000 [source Tc-99 （0.043 µCi）], 17,000 [source C-14 （0.130 µCi）] | | Description | Supplier No. | VWR Catalog Number | Unit | | MC1K | MC1K | 55408-576 | Each | | Monitor 4 | MONITOR 4 | 55408-531 | Each | | Monitor 4EC | MONITOR 4EC | 55408-553 | Each |
