The HERM LB 500 is an additional product in the detector range of Berthold Technologies for flow through measurements.

The high sensitivity Sodium Iodine Crystal enables, combined with a lead shielding and Twin-Cell-Changer, to detect different Gamma emitting nuclides for the flow through analysis. You can use a GM high dose rate counter tube with lead shielding for the measurement of high activity concentrations, such as PET Radio-pharmacy.

The compatibility of the evaluation electronics to external analysis systems is guaranteed. The user has the option of using the analogue output, the TTL signal or the digital output via a serial connector to a PC.

The system can be used either in a „stand alone mode", or be connected to a PC. The HERM system is equipped with a flash memory and a 24 MHz CPU. This allows immediate data processing and easy upgrading. Two threshold levels can be set in the HERM system which activates solenoid valves, also temporally delayed.

The HERM has an internal oscillator with 4 MHz as a reference for validation (GLP) and function control. This signal is available on all outputs and should be checked from time to time.

Using the Berthold Technologies´ WinTerm software enables recording of data via terminal function or by OLE transfer to EXCEL.
