The MSpec scans suspect material and quickly analyzes to determine what nuclide isotope is present and then calorizes the result as Medical, Industrial, Natural Occurring Radioactive Material (NORM), or Special Nuclear Material (SNM).User FriendlyThe MSpec has two modes a user may choose from: Manual or Automatic. Automatic is the quickest and easiest to use mode. Set in Automatic the MSpec will search for and detect radioactive material. Once in range the instrument will automatically begin isotopic identification and display the results. Manual mode gives the user greater control including the ability for longer scan times which increases the accuracy of results. This is especially important if there are multiple isotopes present in the same sample.RadView SoftwareR adComm’s exclusive RadView software interfaces with a user’s PC and enables a user to see detailed results of recorded scans in a Histogram format. Each result can be edited with comments, saved as a PDF and archived for future reference or email compatibility.LAURUS Systems, Inc. - Ph: 410-465-5558 - Fax: 410-465-5257 - LAURUS Systems, Inc. - Ph: 410-465-5558 - Fax: 410-465-5257 - RadView PC Software Program for Data ManagementMECHANICAL∙ Rugged Case: 4.75” x 2.5” x 1.22” (12 cm x 6.4cm x 3.1cm) ∙ Display Window : 1.56” x 1.81” (3.96cm x 4.6cm) ∙ Weight : 0.44lbs (200g)∙ Five Push Button Actuation Mini USB Connector for Internal Battery Charging∙ Operating Temperature Range: 14ºF to +113ºF (-10°C to +45ºC) ∙ Thru-hole for Audio Alarm∙Shock resistance – 1 meter drop test ELECTRICAL∙ Micro-Controller Based Architecture ∙ 1.56” x 1.81” (3.96cm x 4.6cm) LCD with Backlight∙ Backlight Auto-Off (180 seconds) with Push Button Auto-On ∙ Audio Alarm with Vibration∙ Stable Low Noise H.V.
