1. Hanna Mini Titrators
If you want to upgrade from manual titration to improve your accuracy and consistency, a mini titrator is just what you need. The minis are perfect for those who are looking for something fast, accurate, and simple. There's no guesswork with the mini titrators, because everything for your specific testing is included.
Minis give you fast and focused measurements
Mini titrators are perfect for simple and reliable testing of wine, water, dairy, and fruit juice. Each one is dedicated to a single use and designed to provide fast, accurate measurements with minimal setup.
A dedicated device means simplicity – every mini titrator comes preprogrammed with methods, and also include premixed reagents and an electrode specific to your testing need. These autotitrators also feature intuitive navigation screens which show you accurate measurements with just a few easy steps. 
Get accurate and repeatable results every time
Mini titrators provide accurate measurements with the piston-driven dosing system, which provides precisely controlled reagent dispensing. Based on the electrode's response during the titration, the volume of titrant that is dosed is automatically adjusted to allow for faster, more precise titrations. Each mini uses an official method to automatically perform titrations to either a fixed endpoint (based on the official methods) or to an equivalence endpoint.
Mini titrators provide organization and traceability
Upgrade from handwritten data notes with the logging capabilities of a mini titrator. They can log the data of up to 400 different samples which can then be transferred to a USB drive or computer. These titrators can also track good laboratory practices (GLP), such as recent calibrations and buffers used. These features give you confidence in every measurement.
2. The Hanna HI901C Advanced Automatic Titrator
This advanced autotitrator is perfect for someone who needs accurate results in a high throughput environment. This reliable and easy-to-use device excels when dedicated to a single use. (It does, however, provide the flexibility of doing much more.)
Compared to mini titrators, the HI901C autotitrator features greater precision as well as the ability to perform titrations for a variety of methods or samples. When used as a dedicated workstation, automatic titration results are available at the push of a button.
More versatile than mini titrators, but just as easy
Unlike the mini titrators, the HI901C is capable of performing acid, base, redox, and selective ion titrations all in one device. To accommodate your sample variety, this model can store up to 100 customizable methods of analysis. When dedicated to a single use, hardware needs to be changed less often and maintenance is simplified.
Improved precision with advanced dosing algorithms
Being accurate while performing manual titrations can be difficult; the precise dosing pump in the HI901C makes it easy. It's capable of dosing extremely small volumes of reagent to achieve a very narrow endpoint. With it’s unmatched 40,000 step piston driven pump, there's no other autotitrator like it.
This device also features a more advanced dosing algorithm than the mini titrators; the dosing algorithm allows for more timely and accurate titration results. It provides larger doses at the beginning of a titration and smaller, more precise doses near the endpoint. The algorithm can also be customized to suit your specific titration needs!
3. The Hanna HI902C High Performance Automatic Titrator
Our high performance autotitrator has the same features as the advanced version, plus more. The HI902C also boasts precision reagent dosing, linked analysis methods, multiple equivalence point testing, and automation.
Complex samples are now easier
Do more with automation
The HI902C allows for automation to accommodate a busy schedule. Let the titrator do the work for you with a connected autosampler that allows for consecutive testing of up to 18 samples. Automation frees up your time to do what’s most important, like analyzing your data!
System expansions
Who doesn’t love options? The HI902C autotitrator has the option for expansion to help you achieve greater productivity. It can be enhanced at any time with extra burettes, stirrers, and input boards to fit your growing needs.
4. The Hanna HI931 Automatic Potentiometric Titrator
This leading automatic titrator brings the ease-of-use of the HI901C to you in an updated and compact instrument designed to be the answer to your dedicated titration needs.
Maximize Your Workspace
Like the HI901C, the HI931 is able to perform multiple titrations including acid/base, redox, ion selective electrode titrations, and photometric titrations. All of this capability comes in a smaller package, at a 50% smaller footprint compared to the HI901C, you can save space on your lab bench while maintaining high precision and accuracy in your measurements.
Easy To Use
Virtual keys on the HI931 allow you to easily navigate between screens and menus without getting lost. The keys are responsive and work quickly to get you where you need to be. If you need more information, you can always select the dedicated HELP key.
Durable Design
New and improved, the body of the HI931 is made out a durable, heat-resistant, and stain resistant material called Cycoloy®. The display, buttons, and inner electrical parts of the titrator are fully sealed. This prevents damage from spill, and makes cleanup easy.
Flexible Electrode Holder and Adjustable Arm
The electrode holder is able to hold up to 3 electrodes, 4 tubes, and 1 temperature probe - all at the same time. This sounds like it would be bulky and hard to maneuver to submerge the probes in your sample, but it is not! The holder is angled, and you can remove the stirrer and use a stir plate to handle small volume samples with ease. The arm for the holder has a simple press-to-release button design to adjust the electrode holder height. If you need even more room, you can reverse the electrode holder.
5. The Hanna HI932 Advanced Automatic Potentiometric Titrator
Our sate-of-the-art HI932 brings the titration capabilities of the HI902C to the next level in a 50% smaller instrument. The HI932 still handles multiple analyses and has the 40,000 step pump for the precision you rely on.
Streamline Your Testing
Not only does the HI932 perform tests such as acid/base, redox, ion selective electrode titrations, and photometric titrations, it also can perform linked analyses. A linked analysis, or linked method, allows you to run two titrations back to back in the sample sample.
Automatic Reagent Addition
An option on the HI932 is to have a peristaltic pump. The pump can be programmed to dispense a specified (programmed) amount of reagent by volume into your sample. This helps remove extra handling of reagents and chemicals, as well as introducing consistent dosing and accuracy to your tests.
Built-In Spill Handling
Like the HI931, the HI932 has a Cycoloy® body that is sealed. You do not have to worry about small spills as the electronics are sealed, and there is an external gutter to guide liquids away from the important connectors and electronics.
GLP Management
Good Labratory Practice (GLP) information is digitally recorded with each sample. You can program in sample identification, the company, and operator name. The date, time, electrode ID codes, and calibration information can all be included in reports as well.
6. The Hanna HI921 Autosampler for Automatic Potentiometric Titrator
Expanding your sample handling capabilities is easy with the HI921 Autosampler. The autosampler is designed to be used with the HI902C Automatic Titration System, and they interface together directly. Either a 16 or 18 beaker tray allows you to set up your samples, select your method, press start, and let it run.
Chemically Resistant Pumps
Up to three peristaltic pumps can be connected to the HI921. These pumps can be used for reagent addition, sample leveling, or waste removal. All components of the pumps are chemically resistant. Talk to a Hanna technical representative before ordering to fill us in on what your sample matrix is. We can help to guarantee pump life longevity through chemical compatibility.
Optical IR Beaker Detection
An optical infrared (IR) beam is used to detect the presence and absence of each beaker. You can program the HI921 to handle a missing beaker how you deem fit; you can skip the missing beaker, pause the sequence, or stop the titration sequence.
A Titrator for Every Need
Automatic titrators are available in many varieties. They range from the most versatile, high throughput level to simple, single-use models. All Hanna titration systems provide an easy way to increase throughput, accuracy, and traceability in any field. It's only a matter of finding the one that is right for you.
