　　 Instrument Introduction

　　The V-310S Karl Fischer coulometric moisture analyzer features a 5.7-inch capacitive high-definition color touchscreen, offering effortless, smartphone‑like operation. Its intuitive, straightforward interface and navigational controls minimize the learning curve, enabling rapid proficiency. With its proprietary circuitry and software design, it delivers exceptional performance, including high accuracy, fast electrolysis, short equilibration times, precise blank subtraction, and reliable, trustworthy analytical results.

　　It is primarily used for the analysis of various chemical products, advanced materials, pharmaceuticals, and petroleum products. It delivers exceptional accuracy and excellent reproducibility, particularly for samples with low moisture content—for example, in lithium‑ion battery electrolytes, it can detect moisture levels below 10 ppm while maintaining outstanding repeatability.

　　Unaffected by environmental factors, with automatic drift monitoring.

　　The system automatically detects environmental drift and precisely compensates for it, ensuring that moisture measurement results are unaffected by environmental conditions or stirring speed.

　　The connected KF oven can also automatically detect and compensate for moisture in the carrier gas, further reducing the requirements for the carrier gas and lowering users’ operating costs.

　　Multiple endpoint determination methods, compatible with a wide range of reagents.

　　It features multiple endpoint‑detection modes, including relative drift; relative drift plus time; measured potential plus relative drift; and measured potential plus time. These options enable users to select the most appropriate method based on environmental conditions and sample characteristics.

　　It employs a dynamic drift‑based algorithm to determine the endpoint, ensuring robust performance unaffected by environmental conditions; it can be used with confidence even in high‑temperature, high‑humidity environments.

　　The endpoint potential can be set, making it suitable for Karl Fischer reagents from various manufacturers and models.

　　The system comes with multiple built-in methods, and the result units are customizable.

　　The system comes preloaded with five methods and eight built-in formulas, making it suitable for a wide range of samples, including solids, liquids, and gases.

　　Measurement results are calculated automatically, including percentages, ppm, mg, and more; experimental records compliant with GLP are generated, documenting measurement time, moisture content, percentage, system time, operator, and other relevant details.

　　Carefully selected industrial-grade imported components ensure the instrument’s reliability.

　　All internal components are sourced from leading international manufacturers and meet industrial‑grade standards, ensuring the instrument’s stability and reliability.

　　Capacitive touchscreen makes navigating the menu even more convenient.

　　The instrument features a capacitive touchscreen, which differs from traditional resistive touchscreens by offering more responsive touch and simpler operation.

　　A navigation‑style menu makes function options easy to spot, ensuring quick and intuitive instrument operation.

　　The displayed content is more comprehensive and intuitive.

　　It simultaneously displays water content, measurement time, PPM, percentage content, electrolytic current, potential, and system time, making the experimental process clear at a glance and enabling timely identification of any issues.

　　The electrolytic current is continuously adjustable, and the test results can be corrected.

　　Electrolysis current: 0–500 mA, continuously adjustable; maximum current can reach 500 mA, with a maximum electrolysis rate of 2.8 mg/min.

　　The test results can be automatically calibrated by entering the correction coefficients based on the calibration data.
