PH/EC Testers. What Do You Use?

What brand is it fos?

Tri-Meter is the brand. For me it is fool proof, something I need when I get high.

Here is one site that sales it, I got mine a local grow store.
Tri-Meter Continuous Monitor PPM/pH/Temp

PC....I think it means automatic temperature conversion....or something like that.

The flashing lights you love so much; the easiest calibration system ever; reliability only Bluelab products can provide; the longest lasting replaceable probe on the market; auto-on and off just like the Bluelab EC Truncheon; Automatic Temperature Compensation; a scale of 2.0 pH through 10.9 pH and it's available worldwide.

I just use a pHTestr Ultrabasic

I have an inexpensive Control Wizard for both PPM and PH (two pens). As far as I know they've never done me wrong.

I should have knocked on wood. My PPM meter started sucking. When I add nutes the ppm goes down. I got a little nute burn last feeding and now I know why. I thought it was kind of acting weird when I was mixing that batch, and come to think of it, when I was calibrating it about 3 weeks ago. I changed batteries then too.

I'm leaning toward the truncheon, which is just a style of meter according to the guy in the hydro store. As far as I can tell Bluelab makes the best of these, or at least the most popular. Maybe even their combo meter. It has a lot of things I like about it, especially the 5 year guarantee.

Those individual meters are huge though. I'm thinking they are for pools and not small reservoirs. The lights are cool though.

Milwaukee SM802.... Got it because I got an awesome deal on it... plus had heard good things about it, anyone have one?

[Opie Yutts]

does the truncheon read ppm AND ec? And do you know what the conversion is on them? I asked my hydro guy about liquid tds testers and he said they don't make them so a second tester would be the way to go. I'm sick and tired of getting caught short here. :wtf:

Truncheon is a model of Bluelab products. Their multimeter does everything, but otherwise it's separate ph and ppm meter, both with nice, shiny, flashing lights, both about 2 feet long or something. You ought to check out the videos on their site I linked.

Oaktons.... use Oaktons unless you want to fork out the big bucks.

Hanna makes nice products when you buy their more expensive pieces ($2-300 per individual tester). Their less expensive testers are fragile and need constant recalibration. Don't buy their combination units either because they break more frequently and are typically less accurate than separate meters. Hanna also is a pain in the ass when it comes to warrantying-out their items.

Oaktons are cheap (considering what you get) and they last forever. I use the ultrabasics and when I check the calibration on them every month, my pH meter is seldom off by more than .1 and the TDS changes by only about 20 ppm.

Whatever you decide on, buy a tester with a replaceable electrode... it will save you money down the road.
