Three Core Principles Must Be Followed When Using Lab Companion High-Low Temperature Rapid Temperature Change Chamber

I. Core Principle 1: Familiarize Yourself with Sample Performance to Avoid Test Risks

    Before conducting tests with the Lab Companion High-Low Temperature Rapid Temperature Change Chamber, the primary task is to fully familiarize yourself with the basic performance of the samples. This is the fundamental prerequisite for ensuring test safety and avoiding sample damage and equipment failures. The Lab Companion High-Low Temperature Rapid Temperature Change Chamber is compatible with various types of samples, but different samples have significant differences in heat resistance, cold resistance, and heat generation characteristics. It is necessary to clarify key parameters of the samples in advance, such as material, size, heat generation power, and test tolerance range, to eliminate various risks caused by mismatches between sample characteristics and equipment operating parameters.

    For example, when testing heat-generating samples such as new energy batteries, it is necessary to clarify their maximum heat generation power, ensure that the sample volume does not exceed 10% of the effective space of the equipment, and turn on the equipment's overheating protection function in advance to prevent overheating hazards. When testing fragile composite material samples, it is necessary to rely on the advantage of adjustable temperature change rate of the Lab Companion equipment, reasonably set the temperature change rate to 0.1~5℃/min, avoid sample cracking and damage caused by sudden temperature changes, and ensure the smooth progress of the test.

II. Core Principle 2: Clarify Test Conditions and Standardize Parameter Settings

     Clarifying test conditions and standardizing equipment parameter settings are the core keys to ensuring the accuracy and reliability of test data. The Lab Companion High-Low Temperature Rapid Temperature Change Chamber is equipped with an industrial-grade PLC control system and a 7-inch color touch screen, which can realize fully intelligent parameter control. However, during operation, it is necessary to strictly follow the test standards and sample requirements to avoid the impact of improper parameter settings on the accuracy of test results.

First, it is necessary to clarify core parameters such as temperature range, temperature change rate, and heat preservation time in accordance with relevant test standards (such as GB/T2423, GJB150, etc.). For example, military product testing requires a wide temperature range of -70℃~150℃, and electronic component testing can adopt a temperature change rate of 5℃/min.

Second, it is necessary to accurately set safety parameters, including over-temperature protection threshold, overload protection current, water shortage alarm threshold, etc., to ensure that the equipment always operates within a safe and controllable range.

Finally, it is necessary to reasonably edit the preset test program according to the test process. The Lab Companion equipment can store 100 programs, each supporting 30 segments of temperature change curves, to avoid test interruption caused by program confusion and improve test efficiency.

III. Core Principle 3: Master Equipment Technology and Standardize Operation Procedures

    Proficiency in the technical characteristics and operation procedures of the Lab Companion High-Low Temperature Rapid Temperature Change Chamber is the key to improving test efficiency and extending equipment service life. Operators need to be familiar with the equipment's structure, core functions, and operation specifications in advance to eliminate equipment failures or safety hazards caused by incorrect operations.

    Before starting the machine, it is necessary to comprehensively check whether various indicators such as equipment power supply, refrigerant, refrigerating oil, and water level are normal, and confirm that the sample placement complies with the specifications (100~150mm away from the box wall) to avoid affecting the temperature uniformity inside the box. After starting the machine, first start the equipment's preheating or precooling program, and put the sample into the box only after the temperature inside the box reaches the set initial temperature to prevent the sample from being damaged by sudden cold and heat. During the test, it is necessary to observe the equipment operation status and sample changes in real time, and it is strictly prohibited to open the box door at will. If it is necessary to open it, it is necessary to first pause the heating and humidification functions, and then operate after the temperature inside the box tends to room temperature. After the test, first close the test program, take out the sample after the equipment naturally returns to room temperature, then turn off the equipment power supply, clean up the debris inside the box, and complete the equipment operation record for subsequent traceability and maintenance.

IV. Common Operation Mistakes and Avoidance Methods

Combined with the actual application scenarios of the Lab Companion High-Low Temperature Rapid Temperature Change Chamber, most equipment failures and test errors are caused by operation mistakes, which need to be focused on avoiding and standardized correction:

Mistake 1: Ignoring the heat generation characteristics of the sample and blindly setting operating parameters, leading to equipment overload and sample damage. Avoidance method: Detect the heat generation power of the sample in advance, reasonably match the equipment volume and temperature change rate, and ensure that the parameters are compatible with the sample characteristics.

Mistake 2: Opening the box door at will during the test, leading to drastic fluctuations in the temperature inside the box and affecting test accuracy. Avoidance method: Strictly follow the operation procedures, do not open the box door unless necessary, and if it is necessary to open it, first pause the relevant functions and operate after the temperature stabilizes.

Mistake 3: Directly turning off the equipment power supply after the test without completing the temperature recovery and cleaning process, damaging equipment components. Avoidance method: Strictly follow the process of "closing the program → natural temperature recovery → taking out the sample → cleaning the equipment → turning off the power supply" to do a good job in subsequent equipment maintenance.

    In addition, Lab Companion can provide professional operation training services to help operators quickly master equipment use skills, fully avoid various operation mistakes, and ensure that the test work is carried out efficiently, safely and orderly.
