Overhoff TA 脉冲X射线电离室测量仪

APPLICATION: 应用

Whenever a fast, sensitive ion chamber instrument is needed, the TBM-IC-PULSE-X is the latest in a series. These portable ion chambers are now smaller and lighter.

Based on stable, essentially drift-free electrometer technology.

TBM-IC-PULSE-X是系列里最新版，快速灵敏，这些便携式电离室小巧轻量。

基于稳定的基本上无漂移的静电计技术。

Especially useful in Non-DestructiveTesting or other Industrial or Medical applications where
pulsed x-rays are used.

尤其适用于使用脉冲X-rays无损检测或其它工业，医疗行业应用

PULSED X-RAY RESPONSE:

脉冲X-Ray响应

TBM-IC-PULSE-X is the ONLY radiology imaging portable ion chamber that will detect nanosecond pulsed x-rays.  It will accurately measure the integrated Total Dose from pulsed x-ray machines over a wide range of pulse widths and repetition rates.

TBM-IC-PULSE-X是唯一的用于辐射学影像测量纳秒脉冲x-ray的便携式电离室。此仪器精确测量宽量程脉冲宽度和重复率条件下的脉冲X光机总剂量

This monitor also measures low energies and short pulses that other survey meters ignore to the detriment of worker health.

此监测仪也测量其它测量仪忽略的但对工人健康有影响的低能和短脉冲
