Use of formaldehyde complete equipment to test the process of formaldehyde

1, telephone consultation (reservation)

Customers call the formaldehyde set equipment hotline for consultation. The professional customer service receives the customer consultation, answers the customer's indoor environmental problems, introduces the harm and how to detect the indoor air pollution. According to the specific situation described by the customer, the customer needs the number of detection points, the testing items, Sampling time and testing fee standard, and finally need to check the time and place of customer appointment for on-site inspection, and report the relevant precautions before testing. (in accordance with the relevant state regulations, the independent space for detection space less than 50 should be set as a detection sampling point, and the 50~100 should be set to 2-3 points, and at least 3 points are set at above 100. Ordinary ordinary family customers are calculated according to one room and one point.

2. Home inspection sampling for technicians

The time of the technician to notify the customer one day in advance, and to confirm the location of the inspection, the formalin equipment manufacturer informs the customer about the time to close the door and window before the sample is sampled.

Technical personnel carry professional atmospheric sampling instruments to collect air samples as scheduled (according to national standards, collect 10L gas, flow control at 0.5, acquisition time of 20 minutes)

According to the situation of the test site, analyze the main pollution sources for customers, provide professional answers, and inform some daily environmental protection knowledge.

To send the collected air samples to the laboratory (Note: we do not use the less formal Liuhe formaldehyde detector, the detection data can not be obtained, please pay attention to the distinction).

3. Laboratory analysis of data

After the sample was sent to the laboratory, the professional technicians used large laboratory instruments to analyze the samples, measured all the data, and calculated the specific values of the pollutants. (Note: in general, formaldehyde is measured by spectrophotometer, and benzene and TVOC are analyzed by gas chromatograph after thermal analysis. Be careful not to be fooled by equipment that can read benzene and TVOC directly on the market.

4. Compile the inspection report, sign and seal the seal

The data will be audited by the chief engineer and the test report should be compiled. The report will take effect after the joint signature of the inspectors and auditors and the special report of the test report.

5, delivery report

The staff will telephone the customer to check the data and send the detailed inspection report to the customer by express delivery, e-mail or door-to-door delivery. (Note: electronic report non detection special chapter)
