Hanna InstrumentsHI 98129 Waterproof pH/Conductivity/TDS Tester

I got the tds meter in package and it works great. Turns on real quick measures good. Takes a lil bit as far as the tds counting and ph counting. but it is very accurate within .01 accuracy...Very good quality. I was pricing a tds meter and a ph meter waterproof and temp meters. And its to much hassle to fanagle with different meters....At the end of it all, i only save 10 20 bucks...Meaning..THIS thing has it all in 1 shot, Worth the extra few bucks. Waterproof, tds, ph and temperature all in 1...Can't beat it... Good quality, u can just let it float in the water. The manual says to clean the tip of it after using to make the meter last longer. So thats what i do

I bought Hanna Instruments tester in the middle of last year and it has worked flawlessly for about six months. I have used it every single day. On the 7 month I noticed that the meter would not give me accurate reading so I had to calibrate often. I have purchased a second electrode hoping that will fix the problem. It worked for couple of week and then I was having the same issue. I contacted the company they made some suggestions that unfortunately did not work. I ended up sending meter with electrode back for warranty and they send me the brand new meter with new replacement electrode.The service is amazing and I got a new replacement within 2 weeks and the meter works flawlessly again. It is one of the pricier meter but it's definitely worth the cost. Dealing with company that honors its warranty in fast, professional manner is priceless!!!

Best 3 in 1 meter out there at this price. I’ve had a few over the past 15 years and love em.Hanna makes great ph/tds meters but sometimes the probes sit around and dry out on shelves so you have to soak em overnight to restore them. They are scientific equipment so it does require some maintenance (cleaning, calibrating)

The tester worked as intended. It was also easy to use. If you have a need for it then I suggest buying it.

I think this came to me used when it said it was new. The box was a mess.... The product didn't look new. The instructions didn't match up with what the meter was telling me at all. It was as if it was the wrong directions for the meter. Had to return.waste of money. Bought an AC infinity one for half the price and it works like a dream.

PROS - everything I need to monitor is on one 'pen' Very quick readingsCONS - the cap is very tight - making it difficult to remove smoothly I dislike the fact that you don't change reading modes using the MODE but - you use the SET/LOCK button instead(??)I bought this meter to replace an Oakton PH-2 unit that failed after little more than a month. The Hanna meter calculated right away (be aware that you have to buy buffer solutions to calibrate) AFTER I followed the instructions. I am using the meter daily now - mostly for PH testing - I own a Bluelab truncheon that I still prefer for ECC/PPM readings. I like the fact that the Hanna and the Bluelab give me the same readings in wine or beer musts.One caveat - I did a quick PH test of some honeybee feed (syrup) - it took quite a bit of effort to rinse the ph sensor free of the sugars.So far - I give the Hanna combo meter high marks overall.

I use mine multiple times weekly testing fertilizer blends in my irrigarion system. Monitoring your EC is paramount to a successful growing operation.

This has several competitors. But this has the huge advantage of being:1. totally submersible2. very accurate, pH, TDS, temp.3. easy to move4. easy to store5. pH bulbs on all meters break on occasion - everyone uses glass for pH bulbs, but this model has a very easily replaced pH piece w/bulb that can be replaced. So--- huge thing here -- no need to buy another one over and over.6. Sorry - most important, this measures pH in 0.1 increments w/accuracy. Cheaper testers only get to 1.0 increments. They're cheaper, but not nearly as accurate.Buy it - good product.

I use every day I need

Heureusement que l'on trouve des tutos sur YouTube et que le mode d'emplois peu se trouver sur Hanna.fr !

Trés grand fiabilité, trés précis...

Very Good and accurate results

If you’re a grower, this is a necessity.
