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.
