A new flow-through field fluorometer sonde has been designed for use in downhole tracer tests in 2’’ boreholes. The instrument is capable of determining the partial concentration of two dye tracers present simultaneously in the water. In addition, turbidity can be measured if the water is free of tracers. Although the sonde is aimed at boreholed hydrological investigations, it can also be... Plus

    Summary
    A new flow-through field fluorometer sonde has been designed for use in downhole tracer tests in 2’’ boreholes. The instrument is capable of determining the partial concentration of two dye tracers present simultaneously in the water. In addition, turbidity can be measured if the water is free of tracers. Although the sonde is aimed at boreholed hydrological investigations, it can also be used in surface waters.
