iMetry - Geiger Counter/Gamma Ray Spectrometry


iMetry system is low cost but extreme sensitive pocketsize moblie gamma ray spectrometry, Photon Counter(MPPC) based hyper sensitive scintillation geiger counter, radiation detector system specialized for I131/Cs134/Cs137 survey, used with all generations of iPads. Its extra ordinal sensitivity, powered by Photon Counter, ease of use, will fully satisfy all needs of casual radiation measurement applications, and is a must have item to survive this age. The most important feature is, iMetry is affordable, portable and ease of use. You can have in your bag, or you can have your own in your bookshelf, and you can prepare. At the the moment required, you can check enviroment spectrum instantly by your self, to decide yourself whether if you need action or not. So, at the moment, one of the only item that you can rely on would be iMetry. iMetry will also helps you to decide when to be back. Let's prepare for the future now. To make it work together, iMetry system requires iMetry: the detector module itsself, special audio cable included, iPad, its special dedicated application: iMetry, and external micro-B USB power supply.

Energy Compensation is supported.[#ECsupport]

Energy compensation support is committed from the beginning to support, without any hardware change. It took very long time, to support energy compensation, and software uodates, to meet with recent iOS version.

By recent software update, energy compensation is supported.
No hardware change is required, so all the customter who have iMetry unit from the first release benefits with this software updates.
Using provided previous calibration sheet, that compensates Cs137 based calibration to meet with background radiation level, the provided previous sheet is adopted simply discounting calibration value from Cs 137 based one to 70% value.
To use previous provided calibration value with new application, please check calibration dose setting to check (100% ,70%) selector to switch to %70.
This interprets inputed dose calibration value is 70% of Cs 137 based calibration value, to meet with previous simple compensation just to meet background value, just discounting 70%.

EC(Energy Compensation) enabled measurement mode, provides more precise dose measurement than ever, without any change of sensor hardware, just with software updates.

iMetry retail price $512 → $298, (Additionally requires $9.99 iMetry software from iTunes store for full features).

iMetry - Spectrometry/Geiger counter main unit

  • Refer to official page for details.
  • When used in combination with an iPad application, iMetry can take radiation dose measurement and basic radiation spectrometry.
  • iMetry is powered through USB.(USB power supply must be prepared separately)
  • When iMetry detects radiation, red LED blinks at according brightness. If you get used to iMetry, you may be able to guess nuclear species with the way of LED blinking, aside from practicality ;-)
  • While usual radiation meters may show unstable values, iMetry, being 10~100 times more sensitive than radiation meters of the same class, and with much longer moving average window (MAX 1 hour), easily converge to stable value by measurement time.

iMetry App

  • Official iPad Apps
    • iMetry Lite(FREE)and iMetry(¥1,000) are available.
    • iMetryLiteIcon.jpg iMetryIcon.jpg
    • FREE version has measurement time limitation(15 minutes)
    • Paid version has spectrum data saving and CSV data export features.
    • iMetry App is not necessarily iMetry main unit exclusive, but officially supports RadAngel, may (with luck) work with other radiation meters or spectrometers with audio output.
