		MINIHYD Karl Fischer Titrator

Fast and Easy Karl Fischer Moisture Meter Product | Small | MINIHYD

MINIHYD KF moisture meters have been specifically designed for the determination of water content in oils. Combining coulometry with the Karl Fischer method, MINIHYD KF titrators determine the water content of samples by measuring the amount of electrolysis current necessary to produce the required iodine – this is an absolute technique which does not require the calibration of reagents. MINIHYD KF titrators have been developed in response to many requests from customers in routine laboratories, off-shore platforms and in the field. The built-in battery and optional carry case provide the versatility required by the laboratory and also the ease of use and portability required by the field engineer.

The MINIHYD KF offers many advantages over competition. Easy to use – simple to program so that only a single button needs to be pressed, everything else is automatic. Complete with a built-in high speed printer, everything in a single footprint and small space requirement. Results can also be downloaded via the Results Manager software package onto a PC spreadsheet.

Small, Fast and Accurate
MINIHYD offers a state-of-the-art solution for titration testing: The small size, the built-in-battery and the car-adapter allow for field application in addition to general laboratory use. Its advanced software makes it an outstanding performer for routine quality control and more detailed research applications. MINIHYD works with the patented ACE (Automatically Compensated Errors) control system, which guarantees bias-free results.

Results Manager
This is a windows application that allows you to view and print sets of results created by the MINIHYD KF Moisture Meter. It can download results directly from the titrator through a serial port connection, or open result files previously saved to disk. The Results Manager Software is supplied as a standard item with the MINIHYD KF.

Coulometric Reagents
Cou-Lo Formula reagents offer optimum performance with MINIHYD KF titrators. Our packaging concept has been based on advice from the HSE (Health & Safety Executive) to enable non laboratory personnel to work more safely. Cou-Lo Formula reagents are safer to use and safer to store. Each MINIHYD unit is shipped with a batch of four packets of Cou-lo Formula reagents to save you time and money.

Wide Range of Applications
Though primarily used for assessing the water content in petroleum and petrochemical products, the MINIHYD is able to measure the water content in virtually any liquid substance. Therefore the areas of application include industries such as:
* Petrochemical (oils, gasolines, solvents, fluids …)
* Power (electricity)
* Chemicals
* Gases
* Automotive
* Aviation
* Pharmaceuticals & Toiletries / Cosmetics
* Contract Laboratories
* Universities

Principle

Product | Medium | MINIHYD Principle 1
Karl Fischer titration is simply a means to measure water content of samples. Modern instruments, such as the MINIHYD, use the coulometric principle, whereby the water present in the sample is coulometrically titrated to a predefined end point at which there is a minute excess of free iodine present. Stoichiometrically, 1 mole of water will react with 1 mole of iodine, so that 1 milligram of water is equivalent to 10.71 coulombs of electricity. Combining the coulometric technique with Karl Fischer titration, MINIHYD titrators determine the water content of the sample by measuring the amount of electrolysis current necessary to produce the required iodine. This is an absolute technique which does not require calibration of the reagents.

Product | Medium | MINIHYD Principle 2
Using the latest pulse current technology and the patented “ACE” control system, (Patent No.GB2370641), the MINIHYD automatically selects the appropriate titration speed dependent upon the amount of water present in the sample. The titration speed is reduced as the end point is approached, and when the titration is completed, the instrument prints out and displays the results.
