• Provides an easy to navigate User Interface that allows the user to get all the information they need quickly.
• GammaGuard has 4 views each with with unique purposes.
• Simple view includes information on the detector, a visual gauge and current dose rate.
• Details view includes extra details to give the user more insightful information such as: Counts received in the past second, Current Count/Dose Rate, Total Count/Dose, Total Time, and Overall Count/Dose Rate.
• Interpret view includes Current Count/Dose rate, Total Count/Dose, as well as a warning message depending on the current mode
• Graph view includes a graph that plots the Count/Dose Rate values over time. The user can select values to see the GPS coordinates where that reading was taken, the time at which it was taken, and the Count/Dose Rate. While a value is selected the user can open the gps coordinates in the native maps app to view where the reading was from.
• The graph view has 3 graphs: Latest, Overall History, and Selected Interval.
• Latest will plot the last 1200 points,
• Overall History will split all the readings into 50 intervals and plot the minimum and maximum points within that interval.
• Selected Interval allows you to view up to 1200 points centered around a point from the history graph.
• Gamma Mode will show Dose and allow the user to use the Interpret view to receive a message, warning the user how long they can receive the current dose rate before they reach the Routine Dose Limit and the Emergency Dose Limit. It also shows the user the percentage of each limit that they have reached.
• Contamination Mode will show Counts and allow the user to use the Interpret view to receive a message, warning the user whether the area exceeds the Hot Zone Level(Only available on contamination capable detectors).
• Takes advantage of one consistent User Interface across all CT007 series detectors, so that there is only one system to learn.
• Many customizable settings allowing the user to tailor the experience to exactly what they want including: Units, Warning Alarm and Beeping(both for iOS device and detector), Data logging, and many more options.
• Alerts the user to elevated radiation levels.
• Changes navigation bar from green, to yellow, to red, to indicate low, elevated, and high levels of radiation.
