Connect and Forget

Small enough to fit in a belt pouch or a pocket, the CT007 requires no interaction with its user. It works directly with your SmartPhone via Bluetooth - allowing you to monitor the gamma radiation levels wherever you are, without bulky, heavy or complicated equipment.

Two Operating Modes

In Power Save mode, the CT007 connects to the phone, via Bluetooth, when it encounters elevated radiation levels. If radiation levels are normal, the CT007 will check in with the phone at regular intervals to communicate its battery status and will then drop the Bluetooth connection, to save power.

In Survey Meter mode, the CT007 is continually connected to the phone and the phone displays the current radiation levels. Survey meter mode is used to locate the source of radiation, once elevated radiation levels are detected.

The video to the right demonstrates these two modes. If you can't see the video, please try again from your home computer. (Some institutions are blocking content hosted on Google.)

The CT007 is compatible with most phones running a standard Android operating system (anything called "Nexus") 2.3 or above. Unfortunately, some manufacturers use proprietary UI overlays. These can cause compatibility issues. The CT007 was compatible with all Motorola Android phones tested. It was compatible with all Samsung "Nexus" phones, as well as all Samsung phones running Android 4.1 and higher. LG phones seem to work, as long as the proprietary LG "On-Screen Phone" app is disabled. This is not an issue with the Nexus 4, since it does not have the proprietary app, and the CT007 works perfectly with the Nexus 4. The CT007 should not be used with HTC phones.

It's Easy!

Unlike other devices, the CT007 requires no new interface and thus has almost no learning curve. Simply turn it on, connect to it with your phone's bluetooth using our App and choose your operating mode.

The App allows you to customize your personal warning level to suit your needs and environment, switch operating modes, alerts you with the vibration function of your phone and a distinctive warning message and displays your current exposure data.

The display is easily switched between traditional units (mrem and mrem/h) and SI units (uSv and uSv/h).

Additionally, a stand-alone version of the CT007 is available. Consisting of the same functionality as the original when in proximity to the smartphone app, this new unit will also work on it's own - with a built in screen, buzzer and button for operation.

Institutional Deployment and Expert Guidance

Since the CT007 uses a smartphone as its user interface, it has access to the phone's communication capabilities. These can be used to upload the radiation data to a central database. This, in turn, facilitates expert monitoring and coordinated response. This functionality requires a different app.
