Model Description:
"Beam-Rite" CRT Analyzer & Restorer

Model Details

The CR7000 quickly and accurately tests and restores most CRTs. The CR7000 tests analyze the electron gun and provide you with accurate information about the gun's condition. The CR7000 provides six types of cathode restoration plus a G1 shorts removal feature to bring extra life back to most weak or shorted electron guns.


  • Tests For All CRTs, Including: Computer Monitors, Video Displays, Televisions, Projection TVs, Scopes, and special application CRTs The CR7000 now has full dynamic range to test all CRTs - old and new
  • Newly Designed Sockets Allow Easy Connection To Hard To Reach CRTs - New socket design allows the user to test projection TVs and computer monitors faster and easier
  • The Most Accurate And Thorough Tests Of Any CRT Tester - Exclusive sliding "Good/Bad" scale duplicates manufacturer's test for the most accurate test results available - Exclusive "Low Level" and "High Level" tracking tests locate color tracking pr
  • The Easiest To Use CRT Tester On The Market - Simply connect one of the six supplied adapters to test virtually all new CRTs without setting and resetting cumbersome setup switches - Tests all three guns of color CRTs, with simultaneous display of
  • The Safest and Most Effective Restoration Techniques Available - Progressive Restoration Guarantees The Safest Possible Restoration. - Six levels of "Progressive Restoration" - Self-limiting shorts removal function - Three times the restoration

  • G1 Shorts Test : 20 megohm center scale H-K Shorts: 2 megohm center scale
