FAQ's of Karl Fischer Titrator KAFI+:

Q: How does the Karl Fischer Titrator KAFI+ determine moisture content?

A: The KAFI+ utilizes the coulometric titration method, which measures the amount of electrical charge required to react with water in the sample. This allows for precise determination of water content from 10 g to 200 mg H2O.

Q: What are the main benefits of using the KAFI+ in a laboratory setting?

A: The KAFI+ offers high sensitivity (0.1 g H2O resolution), automatic endpoint determination, and low drift for reliable results. Its digital LCD display, internal memory for result storage, and rapid analysis improve efficiency and data management.

Q: When should I opt for the KAFI+ over other moisture analyzers?

A: Choose the KAFI+ when you require precise moisture determination in small to moderate sample sizes, need compliance with CE standards, or require automated and accurate results in environments with up to 80% ambient humidity.

Q: Where can the KAFI+ be reliably used?

A: This titrator is ideal for laboratories, research institutes, and quality control departments. Its robust design and materials make it suitable for demanding laboratory environments across India.

Q: What is the process for introducing samples and starting a titration with the KAFI+?

A: Samples are manually introduced using a syringe into the titration vessel. The magnetic stirrer ensures homogeneous mixing, and the device automatically tracks the titration, determining the endpoint and storing results for review.

Q: How does the KAFI+ ensure accuracy and minimize errors during titration?

A: With platinum electrodes, precise current control (up to 400 mA), and automatic endpoint detection, the KAFI+ minimizes operator error and drift, ensuring consistent accuracy within 0.3% over its specified range.

Q: What are the key advantages regarding the KAFI+'s connectivity and data storage?

A: The KAFI+ features RS232 connectivity for seamless integration with PCs and printers. Its internal memory securely stores titration results, facilitating traceability and efficient data management within laboratory workflows.
