• Lab Two-Chamber Thermal Shock Chamber

  Nov 03, 2025

  The two-chamber thermal shock chamber is a highly reliable environmental testing device specifically designed for evaluating the ability of products to withstand extreme temperature changes. It simulates harsh temperature shock conditions to rapidly expose the possible failures of materials, electronic components, automotive parts and aerospace equipment during rapid thermal expansion and contraction, such as cracking, performance degradation and connection faults. It is a key tool for improving product quality and reliability. The core design concept of this device lies in efficiency and harshness. It has two independently controlled test chambers inside: a high-temperature chamber and a low-temperature chamber, which are respectively maintained at the set extreme temperatures continuously. The sample to be tested is placed in an automatic mechanical basket. During the test, the basket will be rapidly switched between the high-temperature zone and the low-temperature zone under the program control, instantly exposing the sample to a huge temperature difference environment, thus achieving the true "thermal shock" effect. Compared with another mainstream three-chamber (static) impact chamber, the significant advantage of the two-chamber type lies in its extremely fast temperature conversion speed and short temperature recovery time, ensuring the strictness and consistency of the test conditions. It is highly suitable for testing samples with sturdy structures that can withstand mechanical movement, and the testing efficiency is extremely high. Its working principle determines that during the testing process, the temperature fluctuation of the high and low temperature chamber is small, it can quickly return to the set point, and is not significantly affected by the sample load. This equipment is widely used in fields such as semiconductors, integrated circuits, national defense science and technology, automotive electronics, and new material research and development, for conducting reliability tests as required by various international standards. Its main technical parameters include a wide temperature range (high temperatures up to +150°C to +200°C, low temperatures down to -40°C to -65°C or even lower), precise temperature control accuracy, and customizable sample area sizes. The Lab two-chamber thermal shock chamber, with its irreplaceable rapid temperature change capability, has become the ultimate touchstone for testing the adaptability and durability of products in extreme temperature environments, providing a strong guarantee for the precision manufacturing and reliability verification of modern industry.

• Dragon Heat Flow Meter Temperature Control Test

  Oct 29, 2025

  Temperature control tests are usually conducted under two conditions: no-load (without sample placement) and load (with standard samples or actual samples being tested placed). The basic testing steps are as follows:   1. Preparatory work: Ensure that the heat flow meter has been fully preheated and is in a stable state. Prepare high-precision temperature sensors that have undergone metrological calibration (such as multiple platinum resistance PT100), and their accuracy should be much higher than the claimed indicators of the heat flow meter to be measured. 2. Temperature uniformity test: Multiple calibrated temperature sensors are arranged at different positions within the working area of the heat flow meter's heating plate (such as the center, four corners, edges, etc.). Set one or more typical test temperature points (such as -20°C, 25°C, 80°C). After the system reaches thermal stability, simultaneously record the temperature values of all sensors. Calculate the maximum, minimum and standard deviation of these readings to evaluate the uniformity. 3. Temperature control stability and accuracy test: Fix a calibrated temperature sensor at the center of the heating plate (or closely attach it to the built-in sensor of the instrument). Set the target temperature and start the temperature control. Record the entire process from the start to reaching the target temperature (for analyzing response speed and overshoot). After reaching the target temperature, continuously record for at least 1-2 hours (or as per standard requirements), with a sampling frequency high enough (such as once per second), and analyze the recorded data. 4. Load test: Place standard reference materials with known thermal physical properties or typical samples to be tested between the hot plates. Repeat step 3 and observe the changes in temperature control performance under load conditions. Load will directly affect the thermal inertia of the system, thereby influencing the response speed and stability.   When you are choosing or using a heat flow meter, be sure to carefully review the specific parameters regarding temperature control performance in its technical specification sheet and understand under what conditions (no-load/load) these parameters were measured. Lab will provide clear and verifiable temperature control test data and reports.

• The Applicability of Temperature Test Chambers to the Testing of Household Environmental Products

  Oct 18, 2025

  A variety of products used in home environments (more common test objects) such as televisions, air conditioners, refrigerators, washing machines, smart speakers, routers, etc., as well as environmental protection products used to improve the home environment: such as air purifiers, fresh air systems, water purifiers, humidifiers/dehumidifiers, etc. No matter which category it is, as long as it needs to work stably for a long time in a home environment, it must undergo strict environmental reliability tests. The high and low temperature test chamber is precisely the core equipment for accomplishing this task.   The home environment is not always warm and pleasant, and products will face various harsh challenges in actual use. This mainly includes regional climate differences, ranging from the severe cold in Northeast China (below -30°C) to the scorching heat in Hainan (up to over 60°C in the car or on the balcony). High-temperature scenarios such as kitchens close to stoves, balconies exposed to direct sunlight, and stuffy attics, etc. Or low-temperature scenarios: warehouses/balconies without heating in northern winters, or near the freezer of refrigerators. The high and low temperature test chamber, by simulating these conditions, "accelerates" the aging of products in the laboratory and exposes problems in advance.   The actual test cases mainly cover the following aspects: 1. The smart TV was continuously operated at a high temperature of 55°C for 8 hours to test its heat dissipation design and prevent screen flickering and system freezing caused by overheating of the mainboard. 2. For products with lithium batteries (such as cordless vacuum cleaners and power tools), conduct charge and discharge cycles at -10°C to assess the battery performance and safety at low temperatures and prevent over-discharge or fire risks. 3. The air purifier (with both types of "environmental product" attributes) undergoes dozens of temperature cycles between -20°C and 45°C to ensure that its plastic air ducts, motor fixing frames and other structures will not crack or produce abnormal noises due to repeated thermal expansion and contraction. 4. Smart door lock: High-temperature and high-humidity test (such as 40°C, 93%RH) to prevent internal circuits from getting damp and short-circuited, which could lead to fingerprint recognition failure or the motor being unable to drive the lock tongue.   High and low temperature test chambers are not only applicable but also indispensable for the testing of household environmental products. By precisely controlling temperature conditions, it can ensure user safety and prevent the risk of fire or electric shock caused by overheating or short circuits. Ensure that the product can work stably in different climates and home environments to reduce after-sales malfunctions. And it can predict the service life of the product through accelerated testing. Therefore, both traditional home appliance giants and emerging smart home companies will take high and low temperature testing as a standard step in their product development and quality control processes.
