LB 134 Universal Monitor II

The LB 134 Universal Monitor II can be used to measure radioactive alpha and beta-gamma contaminations on surface such as floors, walls, desks, objects, clothing or skin as well as gamma dose rate in ambient dose equivalent H*(10). Therefore a large number of detectors can be attached to the basic unit.

Data communication via RS 485 and USB with F²C protocol including PC programm for remote parameter up- and download, data storage and graphical evaluation. Saving data storage, parameter up- and download and firmware upgrade are possible via USB memory stick.

Details

The LB 134 Universal Monitor II is a portable battery-powered instrument. It is comprised of a display unit with microprocessor electronic and a signal processing electronic.

Through the integration of a Geiger-Müller tube it is possible to measure gamma dose rate without the necessity of connecting an external detector.

Due to its attractive and ergonomic design and its low weight the LB 134 is easy to handle. The instrument´s surface can be easily decontaminated.

A few directly accessible function keys suffice to operate the LB 134. Even under adverse conditions, the measured results can be read easily on the LCD display with background lightning.

The LB 134 Universal Monitor II can be used to measure radioactive alpha and beta-gamma contamination, activity as well as dose and dose rate for gamma and neutron radiation in ambient dose equivalent H*(10). The attached probe, depending on the application, will be identified by the LB 134 and the program firmware will be adjusted automatically.

Data communication via RS 485 and USB with F²C protocol including PC programm for remote parameter up- and download, data storage and graphical evaluation. Saving data storage, parameter up- and download as well as firmware upgrade are possible via USB memory stick.
