Adobe (tm) PDF file AB-5/AB-5R Portable Radiation Monitors

AB-5 Portable Radiation MonitorThe AB-5 series of portable radiation monitors are Pylon's most popular model of monitors. This monitor series uses proven photomultiplier tube (PMT) technology to detect photons generated by scintillation type detectors. The monitors are portable and easy to use in a wide variety of applications. A wide variety of detectors and accessories are available for the AB-5 series of monitors.

The AB-5R is an AB-5 that is incorporated in a more rugged chassis. Due to the wide range of detectors designed for these monitors, the monitors are sold without a detector. This allows the User to choose the required detector for their application.



Adobe (tm) PDF file AB-4/AB-4A Portable Radiation Monitors

AB-4 Portable Radiation MonitorThe AB-4 series of portable radiation monitors are another popular model of monitors. This monitor series also uses proven photomultiplier tube (PMT) technology to detect photons generated by the supplied Lucas type passive scintillation cell detector. The monitors are also portable and easy to use. They are specifically designed to passively detect and measure radon.

The AB-4A is an AB-4 complete with a factory installed internal printer and temperature, relative humidity, and barometric pressure sensor module. The factory installed internal printer and temperature, relative humidity, and barometric pressure sensor module are also each sold separately.



Adobe (tm) PDF file WLx Working Level Monitor

WLx Working Level Monitor
The WLx is a popular radon and thoron working level measurement monitor. This monitor used proven, integrated solid state detector technology to detect alpha particles from radon and thoron progeny decay. The built in multi-channel analyzer circuitry and firmware allows the monitor to calculate radon, thoron, and their progeny in working levels (WL). The WLx is portable and easy to use.





Adobe (tm) PDF file CRM-1 Active Radiation Monitor

CRM-1 Active Radiation Monitor
The CRM-1 is a popular industrial radon monitor that is used to actively monitor radon in process gases. The CRM-1 also uses proven photomultiplier tube (PMT) technology to detect photons generated by the supplied Lucas type active scintillation cell detector. This monitor incorporates a lockable chassis that is designed for inclement weather conditions. It is designed to be mounted on a surface such as a wall. It is easy to use.








Adobe (tm) PDF file CRM-2 Passive Radiation Monitor

CRM-2 Passive Radiation Monitor
The CRM-2 is a popular industrial radon monitor that is used to passively monitor radon over an area. The CRM-2 also uses proven photomultiplier tube (PMT) technology to detect photons generated by the supplied Lucas type passive scintillation cell detector. This monitor also incorporates a lockable chassis that is designed for inclement weather conditions. It is also designed to be mounted on a surface such as a wall. It is also easy to use.
