The advanced Geiger counter from SebScan, MS1 is not only a Geiger counter, it also has a builtin FM radio which allows you to listen to your favorite music and news updates while sheltering. The MS1 informs you about dangerous situations both visual and audible by spoken messages in your native language supported with an alarm. The MS1 from SebScan is also able to detect carbon monoxide, smoke and other gasses while the builtin weather station gives you an indication of the expected weather.

The MS1 is designed with the prepper in mind. It works on both AC and DC voltage and can work on external batteries (including mobile phone power banks and cordless powertool batteries up to 36V). The builtin voltmeter gives you a visual indication of the applied voltage while the over-voltage protection protects the unit from applying too much voltage. The unit has a short circuit protection, automatic and resettable fuse and even works with battery wires connected in reverse. This makes the unit very user friendly and allows one to power the unit from a multitude of power sources.

The MS1 is equipped with Bluetooth and comes with it's own Android app (IOS app coming soon) that allows you to use any old phone with Android 4+ as a data server and alarm system. The app creates a database on your phone for the MS1 to store the information on. The alarm feature allows for automated email and SMS alerts to friends and family, informing them about dangerous situations such as radioactivity, carbon monoxide and smoke, all customizable by you.

Housed in a bamboo and aluminum design, the MS1 provides an ecstatic look that may resemble a classic FM radio. This truly is an amazing device that you can rely on in times of need!
