Detail |
|
The LB 126 is a portable Dose Rate Monitor which is used in the entire field of radiation protection. A sealed off proportional counter tube, approved in accordance with the new standard H*10, is used as detector. |
|
Three buttons suffice to navigate through the clearly arranged and userfriendly menu prompting. |
|
Up to 1000 measurements can be stored in the data memory and this data can be accessed and printed out via a RS232 and/or a RS485 interface. Serial data communication with the PC, i.e. reading and reset of the data memory, acquisition of the measurement values, reading the parameters and reset of the dose, takes place via F2C Protocol. |
|
Up to 32 devices can be linked via the integrated RS485 interface within a RS485 bus system. |
