Reply To: Continous HAB monitoring

If you only have one C-FLUOR sensor, then you only need one pair of resistors, since there’s only one analog signal from the sensor.  There ARE two ground wires, which is why I asked how many sensors you were using with this one screw terminal board.  In order to connect two Turner analog sensors to a Mayfly Logger, it’s good to use 2 separate screw terminal boards, since each sensor needs 2 ground terminals.
