Portable megohmmeter 620VL

4-wirefor the aeronautical industry

The AMPTEC 620VL Igniter Tester is designed for testing resistance measurements on explosive devices that also have a diode in series. With 4 ½ digit resolution and multiple ranges up to 2.0 MΩ, the 620VL provides safe and clear resistance measurements each and every time. The 620VL is also a user-friendly product, as it has a built-in RS232C Interface and an Optically Isolated Power capability. Compatible with our OP-519 Rack Mount Tray, this product has been in use for the U.S. Navy Vertical Launch Assembly and approved by many U.S. Government Munitions Safety Boards. The Amptec 620VL Failsafe Ohmmeter is used for testing squibs, explosive bridge wire, flares, and similar components. This product was specifically designed in the event the meter should fall or break, it remains “inert” or safe for ultra-safe testing. The 620VL comes standard with an RS232C interface and runs on 4 rechargeable NICAD batteries.
