Product Description:

Qualtech Products Industry Karl Fischer Titrator is a precision Automatic Karl Fischer Titration System for the professional measurement of the Moisture Content and the Water Content of samples in accordance with the Volumetric Titration Method and the Volumetric Karl Fischer Method.

This professional Automatic Volumetric Karl Fischer Titrator is engineered to measure the moisture content and the water content of samples within the full range with the Volumetric Karl Fischer Test Method.

The Karl Fischer Test Method is performed with two different Karl Fischer Titration Test Methods each offering advantages which might indicate which Karl Fischer Titration Test Method may be best suited for a specific Water Content Measurement Application:

• Volumetric Karl Fischer Titrator
• Coulometric Karl Fischer Titrator

The Volumetric Karl Fischer Titration Method is usually best suited for samples with an expected Water Content of more than 1%. The Volumetric Karl Fischer Titrator requires a specialized Karl Fischer Reagent to perform the Water Content Analysis which has a specified titer which may change over time and requires frequent verification with a Calibrated Water Standard. The Volumetric Karl Fischer Method is less accurate compared to the Coulometric Karl Fischer Titrator but is suitable for larger sample volumes.

The Coulometric Karl Fischer Titration Method is usually best suited for samples with an expected Water Content across the full range from 0.0% - 100.0% and offers a much higher accuracy compared to the Volumetric Karl Fischer Titrator, hence the Coulometric Karl Fischer Titrator is also suitable for samples with a very low Water Content below 1%. Based on the high accuracy of the Colulometric Karl Fischer Titrator it is often referred to as the 'Absolute Karl Fischer Method'. The Coulometric Karl Fischer Sample Container has two compartments, one compartment is for the Anode, the second compartment is for the Kathode. The Volumetric Karl Fischer Titrator offers a higher accuracy and completes sample tests faster compared to the Volumetric Karl Fischer Titrator. In addition, the Coulometric Karl Fischer Titrator doesn't require an ongoing calibration for the Karl Fischer Reagent and the Solvent doesn't need to be replaced after each sample tests allowing for possibly lower ongoing costs and a more convenient application.

This professional Automatic Volumetric Karl Fischer Titrator offers the newest microchip technology for Volumetric Karl Fischer Titration combined with a closed system for advanced user safety, a large LCD Display with Backlight, a Non-Pollution System & Non-Leakage System, Fully-Automatic Sample Dispensing, Fully-Automatic Sample Discharge, Fully-Automatic Karl Fischer Reagent Dispensing, Automatic Cleaning, Advanced Safety Features, a wide range of integrated Automatic Titration Programs, a large integrated Sample Measurement Data Memory, comfortable Softtouch Buttons, user-friendly programming, user-friendly Menu Navigation, Advanced Real Time Monitoring, high accuracy, high precision, an ergonomic design, reliable performance, longevity and much more.

This precision Volumetric Karl Fischer Titrator is the recommended Moisture Measurement Instrument for research and quality management including chemical laboratories, pharmaceutical laboratories, petrochemical laboratories, food test laboratories, agricultural laboratories, cosmetic laboratories and many more.

This professional Karl Fischer Titrator is designed and engineered in accordance with the Volumetric Karl Fischer Titration Method two professional titration methods to measure the trace amount of water and moisture in samples.

The Karl Fischer Titration includes two Moisture Measurement Test Methods:

• Coulometric Karl Fisher Method
• Volumetric Karl Fisher Method

The main principles of both titration methods are related. The Coulometric Titration System is highly sensitive to moisture. It is ideal to determine the water content of samples as low as 0.1 µg and a moisture content of ≤ 200 µg. The Coulometric Titration Method offers highest precision and highest accuracy and is best suitable for samples with a very low moisture content in the range from 0.0% to 1.0%.

The Volumetric Titration System is less sensitive to moisture and water content compared to the Coulometric Titration System and is best suitable to determine a moisture content of samples with a higher water and moisture content in the range from 1% to 100%.

This Automatic Volumetric Karl Fischer Titrator offers a wide range of practical advantages over other methods of moisture determination including automatic testing, user-friendly sample handling, high precision, high repeatability.

This professional Volumetric Karl Fisher Titrator is designed and engineered in accordance with international test standards including:

• ASTM D4377 (Standard Test Method for Water in Crude Oils by Potentiometric Karl Fischer Titration)
• ASTM D6869 (Standard Test Method for Coulometric and Volumetric Determination of Moisture in Plastics Using the Karl Fischer Reaction (the Reaction of Iodine with Water))
• ASTM E203 (Standard Test Method for Water Using Volumetric Karl Fischer Titration)
• ISO 15512 (Plastics — Determination of water content)
