The CT007-T uses solid state technology which offers the ability to withstand air pressure changes without rupturing. The CT007-T can be used as a stand alone detector or in conjunction with the GammaGuard app, available on the Google Play Store and iOS App Store. It wirelessly connects to smartphones via Bluetooth for enhanced functionality.
