Found GREAT DEAL ON COMBO METER! Is it worth it?

Don't take me on it but I could of sworn I remember hearing that Milwaukee made a good meter. For the price I would buy it but I already spent what I could this week on my grow supplies. lol. Ill be book marking that though.

Also ec and ppm are pretty much the same thing. One is used to determine the other. It would have been a better deal if it was ph,temp,and tds.

True but I have an infrared temp measure thing from radioshack I found so as long as my temps stay between 68-78 ill be happy so with this specific meter the sm802 in order to get ppm dont i have to convert using math with ec and tds or something?

I have been using one for about 2 years. Don't totally submerge the probe and you should be good.
It is much better than the cheap ones.

so you can use this to measure ppm even though it says tds and ec? I thought I had to convert? nobody answered me so I ask twice

tds (total dissolved solids) measures out in ppms which is what you are looking for

this may help explain it a little

EC/TDS/PPM What are the differences?

That's a good deal for that price. I have had good luck with Milwaukee meters in the past.

Converting ec using .7 conversion (which most people here go by)

1 ec = 700 PPM
2 ec = 1400 ppm
.5 ec = 350 PPM
