Quality Control Device
The Quality Control Device (QCD) operates as an accessory to the MKIV Coded Wire
Tag Injector. After the tag has been implanted by the MKIV injector, the operator drops
the fish into the QCD where it flows through a tag detection tunnel. Tagged and
untagged fish are automatically sorted through separate outlets. Counters record the
quantity of tagged fish. An audible signal alerts the operator when an untagged fish
passes through the device.
- the QCD weighs about 40 pounds (18.1 kg), is 30 inches high (76.2 cm), 9 inches
wide (24.1 cm) and 45 inches deep (1.1 m)
- the QCD is constructed of high quality marine materials
- the QCD operates through a cable connected directly to the MKIV Tag Injector
- the QCD connects to standard hose fittings, with a water flow requirement of 3
gallons (11.4 l) per minute
- the QCD can detect all sizes of NMT's magnetic tags, including half-length
- lightweight components and folding legs make the QCD easy to transport; many of
the plumbing connections use "quick disconnect" fittings
- a hard transit case is available
- the QCD carries NMT's standard warranty and can be purchased or rented
