I was hesitant initially figuring the chlorine may eat the internals but it was listed in many places as designed for chemical dosing usage for aquariums and with a price of only 21 at my local aquarium shop I thought Id give it a shot.

Make enough marks to be roughly the length of your index finger. Wiring Lets start with the resistivity sensor. A hydrometer is an instrument used for measuring the relative density of liquids based on the concept of buoyancy.

Mold a ball of modeling clay around one end of the straw. So get some distilled water for this. Supplies and Solutions for Every Industry.

It was basically telling me that 1288 mscm equals 824e3 or a TDS of 8240PPM So how does this make any sense. The LEDs are turned on if the sensor readings go out of the predefined limits. Make sure that the clay prevents water from leaking into the straw.
