HI 9828: "Instead of walking around with several different meters, I only need to carry one!"

~MR. F. BRABANDER~

"The 84100 is very small and in a laboratory this is very important, because the space is always limited."

~GONZALO CELAYETA~

"HANNA meters are the best for wine producers, because they are portable and give very quick results."

HI 9828: "The logging feature is flexible and fast. I can’t stress how important fast and accurate logging is when performing multiple readings in a short time period. Downloading of multiple readings into a spreadsheet is fluid and allows quick transfer of our field efforts."

~Rick Laurenzi~

I personally just love the HI98129, I went thru a few competitors meters until I found that one. Just a bit of user end feedback for ya.

I received the 84100 unit from the Complete Winemaker last week, and spent the weekend titrating! Great fun, very easy to use.Again, great machine!

~Ed Wright
Fleur Sauvage Vineyards~

The Hanna titrator is working great. Running SO2s has never been easier. I have already trained Jesse (who has no lab or winery experience) to use it and I am confident in the results.

~Bill Parker
Winemaker
White Oak Vineyards & Winery~

Thanks to Dave, Chris and all the folks at Hanna for helping me set up our new SO2 titrator. Everyone was so helpful and prompt in their response. Cowhorn is a small vineyard in the southern part of Oregon and we really appreciate how the folks at Hanna helped keep our wines moving in the right direction. Thanks again,

~Bill Steele
Cowhorn Vineyard & Garden~

I have found the Hanna 84100 Free SO2 Titrator to provide very reliable results with dessert wines having residual sugar concentrations as high as 24%. The instrument is robust and easy to use, it provides consistent results even after prolonged periods between use.

Dear Mr. Minsk: Our company purchased the Hanna Instruments model 98703 portable Turbidity Meter in April 2008. Since then, it has seen varied and rugged use in the heavy construction industry. It has worked flawlessly in that time. We are very satisfied with the performance of this fine instrument, and believe it has been an excellent choice in turbidity metering. Sincerely,

~Jay Harvester

This facility has utilized every conceivable application of the PCA 310 as we did with the PCA 300 and will continue to do with the PCA 320.Utilizing this series of analyzers has enhanced our process control and we anticipate being able to eliminate compliance exceedances.We have been able to reduce consumption of chlorine and minimize impact to the receiving waters. Better for our bottom line and better for the environment.

~Roy Stanton, Washington Water Service Company~

The system has been working great and has proven to be a critical component to our success this past year!

~Maidson Turnblad, Moore Farms~

I actually use the HI 991003N for pH and temperature checks when I do my part-time job - we build and maintain fish ponds. You have to have a very steady pH and temperature or otherwise all the fish die, so we always rely on the best equipment, which is usually a solid Hanna tester. My favorite part about the HI 991003N is that I can keep it in my pocket all day while I work, climbing in and out of places, doing landscaping work, and it doesn't get de-activated or lose its calibration or anything like that. No matter when I need it, whether I just slipped and fell in a pond, or tripped over a bush and banged into a tree, the Hanna tester just keeps on working, and working well. It only has two buttons, which is brilliant because there's nowhere to damage the machine and it is simple to use. Very nice piece of work.

~Jack Lloyd - San Francisco, CA~

The HI 99121 has been invaluable to us in our business. In growing containerized tree seedlings we rely on quality peat moss as a primary foundation building block for growing our crop.

~Kelly Tower - Eugene, OR~

I use a 9813-0....Have had it for at least two years and it has worked flawlessly. The wand is great for applications that require multiple reservoirs within a short distance and the instant reading make it also ideal for multiple reservoir applications. Calibration is a breeze and I find the want can stay calibrated for extended periods of time so long as the probe is maintained. I will use no other pH/EC meter except the 9813-0.

~Joe Malczewski - San Diego, CA~

In 2009 Salt Lake County undertook a massive data collection campaign to eliminate data gaps identified in our Water Quality Stewardship Plan. We needed a portable multiparameter sampling probe capable of capturing as much data as possible in a single unit with the added difficulty of being rugged enough to capture data in the most extreme environments. We chose the Hanna HI 98280 to be the workhorse behind this project. We enthusiastically endorse the HI 98280 and anxiously await the release of the new model!

~Bob Thompson - Salt Lake City, UT~

I use both the pH checker and the waterproof TDS HI 98312. They are simple to use and provide the accurate results I need.

~D. Goff - Racine, WI~

I'm the Printing Manager at a corrugated box factory in Fremont, Ohio. I use the Hanna portable HI 9125N pH meter daily to check pH of our flexographic printing ink. The Hanna meter is made for industrial use and is capable of withstanding the dust and rough environment in our corrugated box factory. The battery life is exceptional, the display is impressive and easy to use. By simply dipping the probe into the ink, you'll get an instant reading of your ink's pH. I have 4 meters and it's real simple to calibrate them so they are always accurate. I use the #7 and #10 buffer for a good ink range. We keep our ink at 9.0 for good run-ability and trapping of colors. With using the Hanna meter's, we do not have any problems with our ink.

~R. Darr ~

We very much appreciate the great support provided by Mike Bogolawaski in developing methods for and setting up our new Hanna HI 902C Autotitrator. Our laboratory’s work providing chemical testing for a major aircraft industry service facility here in Tulsa has been made easier and more cost effective with Hanna and Mike. Mike’s methods setup work , done prior to his arrival on our site, reduced the effort needed to get up and running to a few small tweaks.

The training provided for our staff was first rate, with many insights and tips gleaned from Mike’s extensive field experience with the system. Mike is focused, patient and personable.

We appreciate the inclusion of this high level of support in our purchase price, and are looking into the purchase of additional units.

~Greg George, Metals Chemistry Supervisor - Sherry Laboratories~

Thank you for producing an excellent pool water testing meter, the HI 98121. I had been looking for a pH/ORP combination for my inground concrete/plaster swimming pool. I have been using the meter for more than a year now and my water has been clearer and algae free. I maintain a pH of 7.2-7.4 and 700-850mv. Here in Anaheim, CA the pool is open all year and the water is a perfect azure blue. With a DE filter and a Hayward Pool Vac, I add Leslie's acid and chlorine. But the key is your pH/ORP meter. Thank you again for an excellent instrument.

~Christopher Taylor~

I've used many different brands of PH and TDS meters and Hanna meters are by far the best. I use them for special applications such as checking the ph of a mixture of water + neem oil + hemp soap for a foliar insecticidal spray (don't want to burn those leaves!) I also use them to check the PH of organic compost teas and anaerobic fermented plant extracts. The Hanna meter is the only brand that I have used that can take an accurate PH reading of soapy water with neem oil, dark brown sludgy compost tea, or some nose piercing anaerobic fermented plant extracts. I also use them to PH test my kombucha and jun. The hanna hand-held ph meters will give readings where other meters give errors.
