I bought this to run 4 perastaltic pumps to automatically measure my nutrients for me in a hydroponic system. The ratios of my nutrients all have a common denominator of 15 seconds of run time. I just set the total number of loops on each channel based on the ratios needed. No more graduated cylinders required, just push the start button and walk away. I have not figured out how to make the inputs work yet. I can't find a manual for this thing so I kind of have to guess how things work so it lost a star. If you try to look it up this is the ptr4-ind not the ptr4-sp. I don't know why it is so hard for vendors to include a link to the manual in the description. Who knows, maybe someday people that sell electronic devices will realize we live in the information age. The manufacturer could even reference a web address on the part itself. Probably makes too much sense
