QA 

 

QA :

1 Q: the test value has been 0, spray

perfume will rise?

A :

Please re-calibrate outdoors. avoid

spices, perfume, paint, cigarettes, air fresheners,

alcohol and other chemical pollutants when

testing, so as not to damage the sensor.

2 Q: Why do I need to calibrate?

A :

Our products work in the form of outdoor

formaldehyde-free air sampling as a benchmark,

and then get indoor air formaldehyde content as

a comparison, so the new machine products for

a long time not used, the detection of

environmental temperature changes need to

change First calibrated and then tested, the

value of this calibration for the subsequent

detection of the accuracy of a great relevance.

Calibration environment must avoid spices,

perfumes, paint, cigarettes, air fresheners,

alcohol and other chemical pollutants, so as not

to damage the sensor.

3.Q: Why PM2.5 readings with the

published value on the site is

not the same?

A :

Because the location and conditions of the test

is difficult to reconcile with the weather station,

the weather station in the city there are several

sampling points, each sampling point measured

data are also very different, the sampling point

of the location is strictly required; height 3 to 30

meters, air circulation, can not be close to the

chimney, furnace and other obvious sources of

pollution. And there are no high-rise buildings,

trees or other obstructions that can impede the

flow of ambient air around the instrument.

 

4 Q: Why is the PM2.5 test value

changing?

A :

PM2.5 data are changing all the times, with the

air, wind, humidity and other environmental

factors change, in the room smoking, cooking

fumes, car exhaust emissions, coal, chimney,

furnace Such as pollution sources will change

the PM2.5 value of this area, resulting in

differences in the detection data.

 

5 Q: Why is the product sounding

when working?

A :

As PM2.5 detection need to collect a lot of

mobile air, in order to ensure accurate detection

of the fan needs strong operation, so a little

sound is normal.

 

6 Q: How much range of detection

of formaldehyde concentration

detector,how many square

meters?

A :

1. The principle is less than 50m3 ,the room

should be set 1 to 3 points;50 ~ 100m3 Set 3 to

5 points;More than100m3 at least 5 points. On

a diagonal or plum blossom evenly distributed.

2.Sampling points should avoid the ventilation,

from the wall distance greater than 0.5m.

3.The height of the sampling point: in principle,

consistent with the human breathing.Relative

height of 0.5m ~ 1.5m between.

 

7 Q: the test value has been 0,

spray perfume will rise?

A :

Please re-calibrate outdoors. Detection of

spices, perfume, paint, cigarettes, air fresheners,

alcohol and other chemical pollutants, so as not

to damage the sensor.

 

8 Q: What is the standard for

formaldehyde (HCHO)?

A : ≤ 0.10mg / m3 ("indoor air quality

standards" GB / T18883-2002)

 

9 Q: What is the standard for total

volatile organic compounds

(TVOC)?

A: ≤ 0.6mg / m3 (GB / T 18883-2002 and

GB 50325-2001 Class II civil construction)

 

10 Q: What is the standard for fine

particulate matter (PM2.5)?
