Too young to be part of the "Black Light" and florescent paints era RF.
What a free spirited time those were. Lol

Yes PW a necessity not to skimp on.
I didn't quite understand the "continuous use" option between the Guardian and the Combo.

Plus I won't purchase these type items. From a third party supplier again.

i havbe used cheap ebay ph/ppmmeters, for last 10 yrs., and they do need recalibrated more ofter than a guardian or expensive hanna, they are just as accurate. I bought the top of the line hanna pen, about 10 yrs. ago and it shit the bed within 6 months. The one I use now cost under $20 and I've used it now for like 2 yrs., and I just proved it to a friend , it reads exact and when it goes, I'll buy another under for $20 ph/ppm meter. Another thing i have found, is they last longer when stored dry.:surf:
 
I will reply to this...not for the sake of an argument.
I have used numerous very reliable portable hand held meters for more than a couple of years. Worked good.
Not reliable enough NOW for my applications.
Always had to have a back up with them.
I have purchased 7 different $14-20 pens in the last 6 months for a backup.
Went through 4 TDS and 3 pH pens and the hassle to return crap. Before I had a reliable backup.

This is what I'm using now. Untill my new unit gets here.
As good quality measuring devices are. The back-up TDS meter failed to function. But, it was fine on test after purchase. Stored properly untill needed. $28 for what???

Continuous operations with Micro dosing monitoring ability.
Self test built in.
Accurate at any temperature, humidity, and electrical disturbances.
2 years unconditional guarantee on the unit.
6 months on the probe.
Tech support +

Not going to get this on eBay for $20.
A difference between a Rowboat and an Oceanliner.

I/We really do appreciate your input.

A LOT of growers can get by with those inexpensive pens.
 
I need one unit that tells me all the essentials at a glance, knowing water lvl, ph and ppm will tell me exactly what the plant is doing or its not doing.
 
I can only imagine. Sounds like a cool place to relax and smoke lit up by neon posters.
