Originating in the late 18th century, the transient hot wire technique boasts a history of over 300 years. Currently, mature transient hot wire technology achieves an uncertainty of less than 1% in thermal conductivity measurements of liquids, gases, and solids, emerging as a crucial high precision method for such measurements.
XIATECH boasts profound technical accumulation and extensive R&D experience in the field of transient hot wire thermal conductivity meters. After over a decade of continuous research, the company has successfully transformed multiple scientific research achievements into a series of high precision, high stability hot wire thermal conductivity meters, with numerous national invention patents. Its product lineup forms a comprehensive matrix, including general-purpose, fluid-specific, portable, and single-sample measurement models, featuring fast testing speed, minimal sample consumption, and wide applicability. These products can meet the thermal conductivity testing needs of various substances in forms such as liquids, gases, solids, powders, and pastes, with a test temperature range of -160 ℃ to 650 ℃ and a test pressure range from negative pressure to high pressure. Customization is also available to meet specific user requirements.
Validated through long-term experiments, this series of devices achieves an accuracy of within 0.5% for standard samples in liquid thermal conductivity testing, enabling the detection of minute differences in liquid thermal conductivity. For solid thermal conductivity testing of standard samples, the accuracy is within 1%. These performance metrics fully meet the demands of research institutions and enterprise quality control departments for high-precision, high-reliability thermal conductivity measurement solutions, and the devices have gained extensive application and high recognition across multiple industries and fields both domestically and internationally. The hot wire thermal conductivity meters can accommodate thermal conductivity testing needs across different material forms, temperature ranges, and pressure conditions, achieving full-scenario coverage from basic research to industrial quality inspection, thus providing users with flexible and diverse equipment options.
