SGP Series – Smart Gamma Probes: Bluetooth – USB – Ethernet – RS-485

SGP Series – Smart Gamma Probes including:

  • Smart Bluetooth Gamma Probes

  • Smart Gamma probes with USB, RS-485 or Ethernet connection

Detection of X and Gamma-rays.

Equivalent dose rate H*10 measurement.

The SGP device is a Geiger-Müller based Smart Gamma Probe providing the ambient dose rate. This device is designed for area monitoring such as Homeland Security, radioprotection and CBRNe risks. Its fully integrated electronic modules and wide spectrum of available connectivity, make its integration practical to system already in place. Its options make it usable as an autonomous device.

The Bluetooth Personal Radiation Monitoring Solution is a small, light simple to operate Personal Radiation Monitor (PRM). It displays on an Android® Smartphone/Tablet or on a PC both the radiation level and the cumulative dose that can also be saved.In that configuration, SGP Smart Probes are controlled from IMS Gamma Detector Android app which provides the following functionalities:

–  Digital display of H*(10) ambient dose equivalent rate measurement

–  Alarm trigger con”guration and audible alarm activation

–  Display alarm status

–  Measurements recording parameter settings

–  Data recording limited only by the control device’s storage capacity

Bluetooth connected SGP Smart Probes can also be controlled through the SGP Series Application if installed on a PC-like device with Bluetooth capabilities.

  • USB: SGP can be supplied as USB for communication.
  • RS485 and Modbus: SGP can be supplied as RS485 for communication.
    It allows easy use in local or wide area networks.
    And also as Modbus to cluster probes, connecting probes between them to insure a unique communication connection for multiple-probes reading.
  • Ethernet (PoE): SGP can be supplied as Ethernet (PoE) for communication.
    It allows easy use in local or wide area networks.
    Additional functionalities include Power over Ethernet (PoE) which raises powering sensors constraints.

SGP Software or non-proprietary protocol for easy use or interfacing.

SGP can be connected to any desktop, laptop or tablet PC running Windows and Android for readout.
Non-proprietary communication protocol to interface the SGP probe to any system already in place.


The SGP Series smart software user-friendly interface provides:

  • SGP probe control
  • Probe parameters settings
  • Digital and graphic real-time display of ambient equivalent H*(10) Gamma or X-ray dose-rate
  • Alarm level setting for triggering audible & visible signal
  • Data processing (start/stop/save)


Specific holders are available to easily maintain the SGP probe during operations.

  • Specific magnetic flange to securely maintain the Smart Gamma-ray Probe on your equipment for fixed monitoring operations.
  • Mechanical arm support to hold and to accurately position the SGP probe.

Also on demand and according to your need we can easily and promptly provide especially designed and robust holders solutions.
