The SF101 fully automatic coulometric trace moisture analyzer utilizes the Karl Fischer coulometric method (coulometry) to determine the water content in samples. As such, this instrument is also referred to as a Karl Fischer moisture analyzer or a coulometric moisture analyzer. It features a high-resolution 7-inch large-screen color LCD display with a Chinese interface, Chinese character display, and touch screen control, making human-machine interaction more intuitive and operation simpler. Compared to similar instruments, it significantly enhances testing sensitivity. This instrument can store 256 historical test records, providing greater convenience for your experiments. With its technological innovation, ease of operation, rapid testing, reliable results, and stable performance, it is widely used for moisture determination in liquids, gases, and solids (for aldehyde and ketone samples, dedicated reagents for aldehydes and ketones must be selected) such as petroleum, chemicals, insulating oil in oil-filled electrical equipment, pharmaceuticals, pesticides, fertilizers, mineral raw materials, lithium battery electrolyte, plastic raw materials, oils for refrigeration equipment, refrigerants, etc. It is an ideal choice in the field of trace moisture determination.
