3 way ph/moisture/light meter

Anyone know what unit of measurement these measure in? It is graduated 0-2000 but it just says light on one side and dark on the other. Its a 2 prong model that you stick in the soil, I have found it useless for reading soil ph so I use it as a moisture gauge, and to check amount of light getting to the lower part of the plants. I just don't know what its measuring lumens, lux, foot candle, or whatever

Bump for at least a go fuck yourself from someone.

that meter is worthless.....it gives me the same reading regardless of the condition

me too. once it said my soil was in the 10 for wetness after a week and a half of only a half watering too.

Actually the moisture gauge is the only reliable part of the fucking thing. Mine works great. I wouldnt use it for anything else though. I bought a fucking Blue Labs Truncheon for PH , Its fucking BAD ASS

ya, the pH check is worthless. i bought a new one that just has one probe to be used for the moisture meter.

i seen a electronic soil pH tester at lowe's the other day, but now i'm leery. guess they always take returns.

think i'll just keep worrying about my water/nutrient pH. Things always stay peachy as long as i'm keeping that under wraps.

I still have all that garbage from years ago--None of those things work worth a shit. I picked up a digital HANNA multi plus soil -tester works like a charm. I wonder how many grows those cheap pieces of crap have ruined?

ive had bad experiences using the same ph meter for long periods of time. Just change them every 6 months. Lol
