Because of these problems, we developed the Pygmy MagHead. The sensing components of the Pymy MagHead are made with solid-state technology, with no mechanical parts to maintain, wear out, or break, and no reed switches to break.
No more whisker hair adjustments
Clean, all digital signal, perfect for the AquaCalc
Made of sturdy brass, not plastic!
Uses a Hall effect digital switch, no micro reed switches to wear out.
Direct meter to AquaCalc cable eliminates poor conductivity problems due to brackish water or shorted wading rods.
Once installed in your current meter, the Pygmy MagHead is ready to plug into your AquaCalc. It can also be adapted to work with the USGS’ Current Meter Digitizer.
The Pygmy MagHead comes complete with all of the necessary hardware to field retrofit your Pygmy current meter. In less than the time it takes to tear down a meter for cleaning, you can have the Pygmy MagHead installed.
The Pygmy Magnetic Head has been reviewed by the Hydrological Intrumentation Facility (HIF) of the United States Geological Survey (USGS). HIF carries the Pygmy Magnetic Head in stock for sale to federal agencies including the USGS. It can also be ordered directly from JBS.
