Radon Scout PMT :: Radon monitor with Lucas cell
The Radon detector uses a replaceable scintillation chamber (Lucas cell) to convert the radiation into light pulses detected by a photo multiplier tube (PMT).
The Lucas cells can either be filled seperately on site, or operated in flow through mode as a continuous Radon monitor. The built in sampling pump can be manually switched on and of. Three different chamber sizes are available. Sensors for temperature, humidity and barometric pressure are very usefull add-ons.
Accessories
The waterproof case made of impact-proof PELI™ plastic is optionally available equipped with a thermal printer and radio modem. Delivered to you with an integrated security lock, the case is entirely protected against unauthorized access even with slightly opened top during measurements.
For a maximum degree of protection, the case comes without cable or tube feedthroughs. If required, they can be applied on customers special demand for extra charge. The modem as well as the printer can easily be dismounted without tools and used separately.
Thermal Printer — having a record on-site
- High-quality printing unit made in Germany (up to 50 mm scrolls applicable)
- The charger for the printer battery as well as a set of additional paper scrolls can also be housed in the case.
Modem — remotely retrieve data during a long-term field measurement
- Radio modem integrated into the case.
- Both the measuring device as well as the modem are powered by the same power supply integrated into the case.
With Net Monitors it is possible to implement a wireless local network for SARAD instruments, or simple to read out the data without a cable connection. The range of the radio link is several hundred meters in case of a free line of sight. For stationary linking, the range can be extended by directional antennas. A PC adapter, called “coordinator” and at least one instrument adapter (endpoint) are required to create the network. The coordinator is connected to the PC by a USB cable. The instrument adapter can be connected to the serial interface (RS232) of the instruments. The link cable is included in the delivery. To power the instrument adapter, either the internal replaceable batteries or an AC/DC wall adapter can be used. The batteries enable an autonomous operation of several weeks. Many instruments are already equipped with an internal instrument adapter.
As soon as an instrument enters the link range of a coordinator, it will be automatically linked into the network. All SARAD software products contain already the network functionality. The communication takes place in the same way like through a cable connection. The only difference is that before any action which requires the communication with the instrument, a selection table with all linked instrument appears on the screen.
The network uses a similar standard like the WLAN with a maximum link power of 100 mW. The endpoint does not send any information as long it is not in the link range of a coordinator.
The software solutions Radon Vision (from version 6.2.0) and dVISION/dCONFIG (from version 3.3.1) contain a complete solution for TCP/IP based communication with the most of SARAD instruments. The Implementation is very easy and does not require special skills in the IT field.
The IP-Box, in fact, is a robust, tiny (15mm x 111mm x 51mm), pre-configured computer with SSD and Windows operational system. The program Instrument Server is already installed in the auto-start folder of Windows (see also application note AN-008: Internet based monitoring networks for SARAD instruments). It will be opened automatically after turning on the power. The IP-Box is equipped with several USB and serial ports to connect the instruments. The connection to the internet can be realized either by LAN cable or WiFi. The WiFi adapter is integrated in the IP-Box.
