ppm measurer tester help?

I guess It would be better than nothing, but I wouldn't count on it lasting a very long time. IMO you get what you pay for. I bought a $70.00 milwakee over a $40.00 off brand and I expect it to last a while longer. The guy I got it from said that he would expect about 1 year from the 40.00 pen but had heard of a guy who was still using one after 2 years. Hope that helps.

for a beginner a cheap model will do fine. once you harvest a couple of rounds, then you can afford somthing nice.
make sure & get calibration solution too. i calibrate my meters 1x per month, but a cheapy might need more.
it might only last you 6 months but @ $15 a pop you could go through 5 of them b4 paying the same amount for a proper meter.
PH is more important than ppm so you should get a ph meter 1st if you dont have one already.

oga lets say equally important lol.I can always control my soil PH with liming my soil but I cant get rid of 350-400PPM of mainly calcium without an R/O filter.Too much calcium locks out magnesium and phosphorous to say the least,and leaves a nasty film on your dogbowl lol.They are both important but PH is actually much easier/cheaper to control
See if you can't at least get a proper EC meter. PPM is ECx500 or, ECx640 or, ECx650 or, ECx700 or, ECx768 or, EC times some number so stupid I can't remember it anymore ... are we confused yet?
EC is EC. Period. PPM is pure fiction that no one agrees on and changes everywhere you go.

its a 3 in 1 that does EC, PPM and CF
shipping from Hong Kong to Denmark was 4-5 working days
thats faster than most danish shops
havent tried it yet though as im running soil atm but planning to do hydro later

so i have a ppm reader and some clibration solution wtf how do i claibrate my meter using solution?
There should be a tiny screw, mine is under the top cap. Turn the meter on, put it in the calibration solution, swish it around and wait for the reading to stabilize. Then you turn the screw untill the readout is the same as your solution(mine is 1382ppm at .5 conversion).
