Mark IV Automatic Coded Wire Tag Injector


The Mark IV Automatic Tag Injector (MKIV) was developed to handle millions of cycles of tag injections. The tags, which come in continuous wire form on a spool, are automatically cut off, magnetized and injected through a hollow needle. The operator then verifies that the specimen contains a tag by dropping the specimen through a Quality Control Device (QCD) where it flows through a tag detection tunnel. If a QCD is not available, the magnetic tag can be verified by using any of the detectors NMT makes for that purpose.

the MKIV Injector is about 18 pounds (8.2 kg) in weight, 10 inches (25.4 cm) wide, 10 inches (25.4 cm) high and 12 inches (30.5 cm) deep
  • the Power Supply, Tool Kit, Touch Switch and 3 non-custom Head Molds are supplied with the unit; a hard transit case and other accessories are available through NMT
  • The MKIV Injector is constructed of the highest quality materials; it is easily programmed from the keyboard and can mark 600-800 fish per hour
  • the MKIV Injector can inject half length (0.5 mm), standard length (1.1 mm), one and a half length (1.65 mm) or double length (2.2 mm) tags
  • the MKIV Injector can be used with either a Head Mold to position the specimen or a needle support tube for freehand tagging
  • the MKIV Injector operates on 12-28 volts DC (about 50 watts)--the Power Supply converts 120 volts AC to the appropriate DC voltage; international customers should request a custom Power Supply
  • the MKIV Injector carries NMT's standard warranty and can be purchased or rented
