Since I am delving into Hydro for my next grow, I will need a new meter. So before I plop down $120 for the units from Ebay that show PPM, PH, Temp, etc.. I thought I would see if I could get some suggestions from the GC Community about what works best for them Links, Suggestions and Personal Experience please.
Ive had really great luck with both of these: Hanna Instruments HI9813-5N GroChek pH/EC/TDS/C Portable Meter w/ Cal Check Nutradip FH1100046 pH/PPM/Temp meter
Hanna Combo Waterproof pH/EC/TDS/Temp HI-98129 Hanna Combo Waterproof pH/EC/TDS/Temp HI-98129 144... save your money and get this... its worth it... and its not much more than what your willing to spend...
im interested as well but nervous on spending upwards of $100 , how long do they last before the electrode needs to be replaced? Also how do you take care of them (storage solution, calibration solution etc.)?
Storage usually depends on the meter type, but if you have an all in one pH/TDS/Temp pen, it is recommended to fill the cab with a 7.01 pH calibration solution and put the cab on the pen. This soaks the little diode at the end of the pen constantly and assures a neutral pH when going to test. There are many quality pH pens that are around $70-$80... getting into the combos is where the price will rise... and then of course the top of the line products can easily go for $400 or $500.
