The FA944  comes fully assembled and tested in our factory.
Just like the “FK944”, this works on the principle that the resistance of water reduces in accordance with the percentage of salt and other contaminants.  The 8 LEDS display the relative conductivity of the water or stream.  For example the green LEDs suggest a lower level of contamination than the red LEDs.

This kit was designed as a school project, and as such ids ideal for class discussion about the environment or testing for salt levels in streams and lakes whilst on school field trips.
