Nutrient Salts Meter
 

i would like to know any information you might have on using a Nutrient Salts Meter, i have bought one of these and have been told that they are vital for optimum results. i am told to keep the CF level on 8 but it seem to read almost 8 with no added solution. i have read the instructions carefully and cant see what i am doing wrong, my ph reading stays pretty accurate. Please send me any information u think i might need. thank you. Amanda vamskd00@iinet.net.au

The electrical conductivity is another method of determining the salinity of your solution. Conductivity measurements are best conducted at 25 degrees C and any difference from this must be compensated for. If their is question about temperature compensation' simply take a reading, change the temperature of the water by 5 or 10 degrees and measure again. It should give the same salinity. Some units give readings in milliSiemens (MS) and require a salinity conversion table. Others read directly in salinity. Regular calibration with a standard solution is recommended.
