The DPM 7001 is a mobile liquid scintillation counter equipped with two photomultipliers, giving it a high counting efficiency and low background noise. It is specially designed for the counting of tritium and carbone-14.
The DPM 7001 is totally innovative in the range of small liquid scintillation counters, as it is the only one equipped with two photomultipliers.
Due to its small size and its light weight (16kg), it can be transported easily on monitoring sites for quick measurements.
It also offers the user many functionalities: Setting of counting window, connection with computer or with thermal printer, spectra, data report in excel format.
The sample is mixed with scintillation liquid and inserted into the counting chamber, equipped with two photomultipliers (PMs).
The two PMs are placed opposite and operate in dual coincidence. Each desintegration is then counted only when it is detected by both PMs in the same coin- cidence time.
DPM 7001 PC control software
The DPM7001 PC control software allows to control and operate the counter from a PC via serial RS 232 communication.
The method manager allows to load a user-defined protocol previously stored for a specific radio-isotope.
Once the measurement parameters are defined or loaded from the method manager, the user can define the sample name and also add a comment.
The software also allows to save measurements done, and to read measurements previoulsy stored. Data can be exported in Excel for- mat file for further data processing.

The software also allows to edit a spectrum after measurement.
