AQUACOUNTER® Karl Fischer Volumetric & Coulometric Titration Instruments
Karl Fischer Titrators are hardly new to North America, having been sold here for the last 20 years. Manufactured in Japan by the Hiranuma Company, Karl Fischer volumetric titrators, coulometric titrators and titration instruments represent the highest standards of performance and quality by which all other titrators are measured. Hiranuma manufactured its first potentiometric titrator in 1965 and continues to offer innovative coulometric and volumetric titrator products for testing moisture on the production line, acceptance testing of raw materials, or developing new products in the R&D lab. Hiranuma's AQV-2100S, the AQ-2100S Coulometric Titrator , and the AQV-2100C Combination Volumetric-Coulometric Titrator all display real-time curves for monitoring the progress of any titration. Easily visualize your results while they are occurring on a large, easy-to-view, backlit liquid crystal display. Store up to 50 results, including data points as well as titration curves in the instrument's memory. No more lost data! Simply retrieve and print out data anytime they are required.
The AQV-2100C Volumetric-Coulometric Titrator has two channels available for both coulometric titrations and volumetric titrations. For those who need single channel instruments now, but may need two channels in the future, the AQV-2100S and the AQ-2100S Karl Fischer titrators are capable of expanding to accommodate your future needs with a factory-installed conversion kit. Similarly, the AQV-2100S, which is a single channel volumetric titrator, can be easily converted to either a dual channel volumetric, or combination volumetric-coulometric titrator. Other combinations are possible; please inquire with your needs.
JM Science's new AQUACOUNTER Karl Fischer instruments offer state-of-the-art performance, with unprecedented adaptability, simplicity and accuracy. Our new low cost titrators, the AQ-300 and the AQV-300 offer the same specifications as the 2100 series but are available at very special low pricing. All AQUACOUNTER titrators are covered by a comprehensive warranty and come with demo Karl Fischer reagent kits formulated to work beautifully with our line of titrators or any others.
Volumetric Karl Fischer Titrator
AQV-2100S
- Multi-channel Capability
- Large Back Lit LCD Display
- Real Time Titration and Background Curves
- GLP/ISO Compatibility
- Automatic Control of Evaporator
- Storage for 50 Results
This dependable workhorse has an extremely wide measuring range... From ppm to 100%, its automatic background compensation function allows accurate volumetric measurements of trace moisture levels. The unit has a 10ml single buret, a single stirrer, and a single volumetric cell. The AQV-2000S can also be converted to either a two channel volumetric titrator or a two channel volumetric-coulometric titrator. The volumetric conversion allows the use of two different strength titrants for maximum analytical flexibility.

AQS-2010 VOLUMETRIC
Automated Evaporation KF Titration System AQS-2010 (Automated Evaporator/Sample Changer EV-2010)
For medium to heavy workloads
Up to 10 samples can be mounted on the turntable at the same time. Up to 99 samples can be run by simply removing the finished sample and adding a new one.
Extremely compact design
A compact upright design for both the heating block and the KF titrator saves your valuable bench space.
Wide temperature range and programmable temperature control
The heating temperature can be set up to 30° C and programmed up to 3 steps.
This feature makes it easier to find the optimum temperature for each individual sample, or allows you to differentiate surface water from bound water.
Integrated Air Pump
Compact, integrated air pump (Optional) eliminates the need for nitrogen carrier gas.
Incorporate both coulometric and volumetric titrator
The EV-2010 automated evaporator/sample changer can be connected with both the AQ-2100 coulometric titrator and the AQV-2100 volumetric titrator, which makes the AQS-2010 a complete automated evaporation KF titration system. For the best accuracy for determining trace level of water, AQ-2100 coulometric titrator is recommended.
