Karl Fischer Coulometer



The Karl Fischer Coulometer is a high-precision instrument used to measure trace moisture content in liquids, gases, and solids.

It works on the coulometric titration method, which provides accurate and stable results.

Moreover, the system is ideal for laboratories in the chemical, pharmaceutical, food, and petroleum industries.

As a result, users obtain rapid, reliable, and highly sensitive measurements with very small sample sizes.

In addition, the instrument reduces reagent use and testing time, which improves laboratory efficiency.

Features :

• First, it provides rapid and precise moisture measurement up to 1 ppm.
• In addition, automatic end-point detection ensures high accuracy and repeatability.
• Furthermore, the touch or digital interface makes operation simple and user-friendly.
• A built-in stirrer and titration cell ensure uniform mixing and consistent results.
• Therefore, the system uses low reagent volume and delivers fast titration speed.
• Moreover, the compact and lightweight design saves valuable bench space.
• The instrument is also maintenance-free, which reduces downtime.
• In addition, data storage with USB/RS232 connectivity allows easy record keeping and transfer.
