Overview

The formaldehyde VOC testing chamber is suitable for industries such as scientific research, quality inspection, furniture, home furnishings, electricians, electronics, automobiles, materials, chemicals, and home appliances.

Product Details

Product Name:Formaldehyde VOC testing chamber(Formaldehyde emission detection release box)

Formaldehyde VOC testing chamberApplicable industries: scientific research, quality inspection, furniture, home furnishings, electricians, electronics, automobiles, materials, chemicals, household appliances.

Product use: Suitable for measuring formaldehyde emissions from various indoor decorative materials such as artificial boards and composite wooden floors, constant temperature and humidity balance treatment of wood or artificial boards, and detection of volatile harmful gases in other building materials. Scientific and reasonable design and manufacturing, easy to use, are products of production enterprises, research institutions, technical supervision departments, colleges and universities, and other units.

operating procedure

1. Preparation work

Environmental Requirements

Ensure that the test chamber is placed in a well ventilated environment without strong electromagnetic interference.

It is recommended to control the room temperature at 20-30 ℃ and the humidity at ≤ 70% RH.

Equipment inspection

Check whether the power supply, gas circuit (such as connecting external gas), and sealing of the test box are normal.

Confirm that the internal sensors (temperature and humidity, VOC sensors) have been calibrated and are within their validity period.

Sample preparation

Cut or install samples according to testing standards (such as GB/T 18883, ISO 16000, etc.) to avoid contamination.

If testing materials (such as furniture, boards), pre-treatment (such as edge sealing, aging) should be carried out according to standard requirements.

2. Device startup and parameter settings

power on

Turn on the power, start the control panel, and preheat the equipment to a stable state (usually takes more than 30 minutes).

Parameter Settings

Set the following parameters according to the testing standards:

Temperature: Commonly set at 23 ℃ or 28 ℃ (as required by GB/T 18883 for 23 ℃).

Humidity: usually set at 50% RH.

Air exchange rate: such as 1.0 times/hour (adjusted according to standards).

Testing time: generally ranging from 24 hours to 28 days, depending on the testing purpose.

Background value calibration

Run the test chamber without load to detect the background formaldehyde/VOC concentration and ensure that the background value is below the testing limit.

3. Sample placement

Place the sample evenly inside the test chamber to avoid obstructing the airflow channel.

Maintain a minimum distance of 10cm between the sample and the box wall to ensure even air circulation.

Record the sample number, location, and placement time.

4. Start testing

Close the box door, start the testing program, and the equipment will automatically control temperature, humidity, and air exchange.

Real time monitoring of data (such as temperature, humidity, VOC concentration), and immediate suspension of inspection upon discovery of abnormalities.

5. Data collection and analysis

Regularly collect gas samples using built-in sensors or external sampling devices (such as Tenax tubes, DNPH sampling tubes).

Analyze the concentration of formaldehyde/VOC using a gas chromatograph (GC-MS/HPLC) and calculate the release rate.

Export data and generate a report, comparing standard limits (such as indoor air quality standards).

6. Test completed

Turn off the device power, open the box door for ventilation until the residual gas dissipates.

Clean the inner walls of the box and sample rack to avoid cross contamination.

Maintenance and Care

1. Daily maintenance

clean

After each test, clean the residue inside the box and use a dust-free cloth dipped in neutral cleaning agent to wipe the inner wall.

Regularly clean or replace the air filter (it is recommended to check it once a month).

Sensor maintenance

Formaldehyde/VOC sensors should be calibrated every 3-6 months, or according to the manufacturer's recommended cycle.

Avoid the sensor from coming into contact with high concentration gases or corrosive substances.

leak test

Regularly check whether the door seal is aging and replace it if necessary to ensure airtightness.

2. Regular maintenance

System calibration

Every year, professional technicians perform overall calibration on the temperature and humidity control system and gas flow meter.

consumable replacement

Replace consumables such as activated carbon filters and desiccants (the cycle depends on the frequency of use).

Software Update

Upgrade device control software to ensure compatibility with the latest testing standards.

3. Long term discontinuation

Disconnect the power supply, evacuate the internal gas, and keep the box door slightly open to prevent mold growth.

Seal key components (such as sensors) against moisture.

Precautions

safety protection

Wear protective gloves and masks during operation to avoid direct contact with harmful gases.

When testing high concentration samples, it is necessary to connect an external exhaust system.

environmental interference

Avoid using volatile substances such as solvents and perfume near the test chamber.

Fault handling

common problem:

Temperature and humidity out of control: Check if the sensor, humidifier/dehumidification module are functioning properly.

Data abnormality: recalibrate the sensor or check for blockage in the sampling pipeline.

The device cannot start: Check for power, fuse, or control system faults.

Complex faults require contacting the manufacturer's technical support.

frequently asked questions

Q1: Poor repeatability of test results?

Possible reasons: uneven sample, temperature and humidity fluctuations, sensor drift.

Solution: Standardize the sample preparation process and recalibrate the sensor.

Q2: Is the background value too high?

Possible reasons: box contamination or filter failure.

Solution: Clean the box and replace the filter, run it without load until the background value meets the standard.

Q3: How to extend the lifespan of equipment?

Regular maintenance, avoiding overload operation, and maintaining a clean and dry environment.

By standardizing operations and regular maintenance, the accuracy of formaldehyde/VOC testing chamber data can be ensured and the service life of the equipment can be extended.
