RTM 2200氡气多功能测量仪介绍：

RTM 2200氡气多功能测量仪各项出色性能在执行复杂测量过程中表现的尤为突出。由于它有多个接口可连接多个附加探测器和输出控制系统，因此可以很轻松地建立起一个多功能的测量站点。 RTM 2200氡气多功能测量仪对于数据采集也没有任何限制，同时可以用于控制各种采样装置（如泵、阀门等）。

RTM 2200氡气多功能测量仪通过连接额外的氡测量腔室（可多达4个）如土壤气体测量探头，室内空气传感器等，单个仪器便可同时测量不同房间的室内氡浓度。额外选装的气压和温度传感器可使仪器建立一个建筑和设施中氡动态的监测系统。 另外也可用于地球物理方面的水体和土壤气体监测。仪器还可根据需要选装NaI(Tl)闪烁体γ能谱探测器和可燃气体、一氧化碳等气体探测器，对于矿井、铀工业方面监测也有很大帮助。 我们可以根据用户的需求对仪器的测量部件进行升级和改造。

RTM 2200氡气多功能测量仪腔室，基于高压静电收集原理，采用多个小体积腔室来保证探测灵敏度，腔室内使用的是SARAD自产的高灵敏度深层离子注入型硅半导体探测器，通过α能谱法来识别区分不同氡子体。 这样设计的优势在于：其对与钍射气具有较高的灵敏度，并且可以使用较低的采样流速（对土壤气体采样有明显优势）；特殊的小腔室设计使得仪器对环境湿度不敏感，这使得RTM 2200氡气多功能测量仪完全不需要同类仪器所必需的干燥器；采用的能谱测量法完全排除了长寿命衰变核素210Po的干扰；仪器所采用的硅半导体有效地区分了由α能谱所产生的不同的氡子体。

可靠性是对任何测量仪器的基本要求。因此，RTM 2200氡气多功能测量仪会储存每一笔的α能谱测量数据。通过对每笔测量数据的查看，可对测量的有效可靠性进行确认。

RTM 2200氡气多功能测量仪所有的测量结果都能在大屏幕触摸屏上显示。使用SD卡便可储存收集到的测量数据。如果安装了GPS模组，每次测量数据还会附带有GPS定位信息。 数据传输可通过USB和串行RS-232接口进行，RS-232接口可连接GSM调制解调器，如果需要，串行接口可更换为无线网络适配器（可组建无线局域测量网络）。

RTM 2200 : Radon and thoron measurement system

Even in the basic version, the RTM 2200 represents the perfect radon/thoron monitor for any kind of radon measurement. The outstanding performance of the unit becomes really visible, if complex sampling procedures must be applied. Due to its versatile possibilities for connecting additional sensors and actors, a multi-parameter station can be created without effort. The Radon/Thoron detector RTM 2200 is not limited to the data acquisition but is also able to control equipment which is required for the sampling (e.g. pumps, valves, positioning etc.).

By connection of up to four additional radon chambers (soil gas probe, indoor air sensor) it is possible to measure the radon concentration in different rooms with one radon/thoron monitor. In addition differential pressure and temperature sensors may complete a sampling system to investigate the radon transportation processes in buildings and facilities.

Another application is the geo-physical instrumentation, where water analytics and sampling of soil gases can be integrated. A spectroscopic NaI(Tl) gamma detector and/or gas sensors for carbon monoxide and combustible gases are very helpful for the mining and uranium industry. There is no limit for your ideas.

The radon measurement chamber, based on the principal of high voltage collection, offers a high sensitivity at a small internal volume. This is a big advantage for thoron sensitivity and it allows to use a small pump rate which is often important (soil gas sampling).

The long term contamination by Polonium-210, known from other measurement principals is completely rejected. There is no cross sensitivity to ambient gamma radiation. Due to its special design, the chamber is not sensitive against variations of the ambient humidity. The commonly used drying equipment for instruments using this principal is not required for the RTM 2200.

We use high quality silicon radiation detectors inside the chamber to separate the various radon daughter products by alpha spectroscopy.

Quality assurance is a basic concern of every radiation measurement. Therefore, the radon/thoron monitor RTM 2200 saves a complete alpha spectrum for each data record. The spectrum always allows to check the error free operation of the unit.

All results are presented on a large display with touch buttons. A SD memory card allows collecting of a huge amount of data if necessary. Each record will be stamped by the GPS coordinates, if the GPS option has been chosen. Data transfer is realized by USB port and serial interface (RS-232). The RS-232 allows the connection of broadband mobile modems. Optionally, the serial port can be replaced by an integrated wireless network adapter (Net Monitors).

The instrument comes with a DAkkS compliant calibration certificate. The calibration process fulfills the requirements of the DIN EN ISO/IEC 17025:2018.
