The TROLL ® Shield antifouling guard is designed to reduce fouling of the
conductivity cell on Aqua TROLL ® 100 and 200 instruments. Reduced fouling on
the sensor improves measurement accuracy and extends the length of instrument
deployments. For optimum performance, replace the coil every 6 months.
