After independent market research, the School of Aerospace Science and Technology at Tsinghua University finally signed an agreement with our company for the A-2 transient planar heat source method thermal constant analyzer. This instrument will mainly be used for measuring the thermal conductivity of liquid samples.
Our company's thermal constant analyzer measures the temperature rise of the probe using a non electric bridge method, which has significant advantages in measuring liquid samples. Because when using a bridge circuit for probe temperature rise measurement, it is always necessary to adjust the balance of the bridge by applying a small voltage for about 2 minutes, and the test can only be conducted after the balance is reached. The adjustment process of this bridge balance will definitely have a significant impact on the temperature rise of the sample, and for liquids, it will also cause convection. The temperature rise and convection before this measurement will significantly increase the measurement error!
Thank you to the School of Aerospace Science and Technology at Tsinghua University for their high recognition and trust in our company's products!
