Operation method and precautions of high temperature expansion instrument

Jul 14, 2025 0

The high temperature expansion meter is a professional instrument used to detect the expansion properties of solid inorganic materials, metals and non-metallic materials under high temperature environment. It has important application value in materials science and engineering research. In order to ensure the accuracy of the test results and the long-term stable operation of the equipment, the correct operation method and precautions are particularly critical. This article will introduce the operation method and precautions of the high temperature expansion meter in detail.

ONE. Operation method of high temperature expansion meter


1. Equipment inspection and preparation


Confirm that the power cord of the equipment is connected normally, the power socket is not loose, and the equipment can be powered on normally. Ensure that the sensor is not damaged and connected firmly. Open the sample compartment and check whether the interior is clean, whether there are foreign objects or residues, and ensure that the sample compartment is in a clean state. Prepare the sample to be tested and ensure that the sample surface is clean and free of impurities. The size and shape of the sample should meet the test requirements.


2. Sample installation

Open the sample compartment of the high temperature expansion meter and ensure that the sample compartment is in an operable state. Place the sample to be tested on the sample table. The sample should be in good contact with the sensor to ensure that the measured data is accurate. Use a fixture to fix the sample to ensure that the sample does not move during the test. The fixture should be easy to operate and firm to ensure the stability of the test.


3. Set the test parameters


According to the material properties of the sample and the test requirements, set the appropriate heating rate. According to the purpose of the experiment, set the temperature required for the test. The set temperature should be within the working range of the equipment to avoid over-temperature operation. According to the experimental requirements, set the appropriate insulation time. According to the needs, set other test parameters, such as cooling rate, data acquisition frequency, etc.


4. Start the test and data recording


Press the start button, the equipment starts to heat and measure according to the set parameters. During the test, monitor the operating status of the equipment in real time to ensure that the equipment is working properly. Pay attention to temperature changes and data recording to avoid abnormal situations. During the test, the equipment will automatically record temperature and expansion data to ensure that the data recording system works normally and avoid data loss

TWO. Precautions for the operation of high-temperature expansion instrument


1. Safe operation: The high-temperature expansion instrument will generate high temperature during operation. Operators should wear appropriate protective equipment, such as high-temperature resistant gloves, goggles, etc., to avoid burns and other accidental injuries.


2. Environmental requirements: Ensure that the high temperature expansion instrument is used in a dry, ventilated and good environment, and avoid operating in a humid or highly corrosive gas environment to prevent equipment damage and inaccurate test results.


3. Regular maintenance: The high temperature expansion instrument needs regular maintenance and care. Including cleaning the sample compartment, checking the sensor, calibrating the equipment, etc.


4. Standard operation: Strictly operate in accordance with the equipment manual and operating procedures, and avoid unauthorized changes to the equipment settings or operating steps.

The operation method and precautions of the high temperature expansion instrument have been introduced to you. Through the correct operation method and precautions, the accuracy of the test results and the long-term stable operation of the equipment can be ensured. I hope this article can provide a useful reference for the majority of users.
