The safety instructions for the constant temperature and humidity test chamber are important guidance for ensuring the normal operation of equipment and the safety of operators. The following is a detailed safety instruction for the constant temperature and humidity test chamber:

1、 Installation environment requirements

1. space requirementsA distance of at least 300mm should be maintained between the test chamber and adjacent walls or objects to ensure the convenience of heat dissipation and maintenance.

2. Temperature and HumidityChoose a location with a perennial temperature of 15-35 ℃ and a relative humidity greater than 85% for installation to avoid sudden changes in environmental temperature.

3. horizontal installationAfter confirming the ground level with a spirit level, proceed with installation to ensure the stability and accuracy of the equipment.

4. Ventilation and light avoidanceIt should be installed in a well ventilated area without direct sunlight, away from combustibles, explosives, and high-temperature heat sources.

5. Dust controlTry to install in places with less dust to minimize the impact on the equipment.

2、 Power and grounding requirements

1. rated voltageProvide a power supply within the rated voltage range to prevent equipment failure caused by unstable voltage.

2. grounding protectionThe equipment must be grounded to prevent electric shock accidents caused by leakage.

3. Power connectionConfirm that the power connection is correct and stable, and place the external power cord neatly next to the test hole to avoid wire entanglement.

3、 Operating standards

1. Check the equipmentBefore starting, check whether the appearance of the equipment is damaged and whether the test box door is well sealed.

2. Sample placementPlace the test sample firmly on the sample rack inside the test chamber to avoid affecting air circulation. The placed items should not exceed one-third of the volume of the test chamber to prevent too many items from blocking the air outlet.

3. Parameter SettingsSet parameters such as test temperature, humidity, and time according to the test requirements, and be familiar with the operation panel and controller functions of the equipment.

4. Operation observationDuring the experiment, closely observe the operating status of the equipment, such as whether the temperature and humidity displays are normal, and whether there are any abnormal noises or vibrations in the equipment.

5. Box door operationDuring the experiment, try not to open the door of the test chamber as much as possible to prevent the high temperature and humidity air from causing harm to the human body. If observation or adjustment of the sample is required, the test chamber should be stopped first. After the temperature and humidity have dropped to a safe range, protective measures should be taken before opening the test chamber door for operation.

4、 Maintenance and upkeep

1. Cleaning and maintenanceRegularly clean the inside and outside of the test chamber, wipe with a soft damp cloth, and avoid using corrosive cleaning agents.

2. Component inspectionCheck the operation of the refrigeration system, heating system, humidification system and other components, and repair or replace them promptly if there are any abnormalities.

3. sealing performanceRegularly check the sealing performance of the equipment and replace the sealing strip in a timely manner if it is damaged.

4. Electrical systemRegularly inspect the electrical system of the equipment to ensure that the wires are not damaged and the plugs are not loose.

5、 Safety precautions

1. Do not move without permissionIt is prohibited to dismantle, process, modify or repair the constant temperature and humidity machine without authorization, otherwise there is a risk of abnormal operation, electric shock or fire.

2. Explosion-proof requirementsThis product is non explosion proof and should not be used in environments with flammable or explosive gases.

3. Fire safety requirementsGood ventilation should be maintained around the equipment to avoid use in high temperature, high humidity, flammable, and explosive environments.

4. Electric shock protectionDuring wiring or installation, the power supply cannot be turned on. During instrument operation, the power input terminal cover must be installed on the terminal board to prevent electric shock.

5. Operational SecurityBefore modifying settings, signal output, starting, stopping, and other operations, safety should be fully considered.

6、 Exception handling

1. Abnormal equipmentIf any abnormal situation is found in the equipment, it should be stopped immediately and professional maintenance personnel should be contacted for repair in a timely manner.

2. High temperature alarmWhen operating at high temperatures, avoid high-temperature airflow rushing out of the box, causing burns or triggering fire alarms.

In short, strictly following the safety instructions of the constant temperature and humidity test chamber can ensure the normal operation of the equipment and the safety of the operators. At the same time, operators must undergo training and assessment, familiarize themselves with the operating specifications and safety precautions of the equipment, before they can operate on duty.
