5-in-1 Air Quality Integrated Detection Digital HD Display Air Analyzer CO2 HCHO TVOC CO AQI Monitor For Living Room Baby Room

5 in 1 Digital Air Monitor co2 Detector for TVOC HCHO PM2.5 PM10 Quality Analyzer Concentration meter,Outdoor and Indoor HLW-100 43% off

Operation method:

CALIBRATION Long press 3 seconds sensor catlibration to restore factory settings “Users need to

operate cautiously” (limited to formaldehyde TVOC  sensor calibration)

Temperature unit ℃/℉ switch.

ON-OFF Switch Chief Press 3 seconds to turn on or off

Tips: (120 seconds preheating is required for the formaldehyde TVOC sensor after booting)0001-0120 preheating timing.

SPECIAL TIPS:Formaldehyde TVOC needs good air ventilation for about 30 minutesbefore the instrument can be used normally. PM2.5PM10 can be detected immediately afte starting.

OPERATION AND PRECAUTIONS：

Check whether the instrument is in good conditionbefore use.

After startup, the instrumentation data can be stable before it can be tested and used.

Formaldehyde TvoC  detection needs 120 seconds pre-heating and timing after booting.  

Indoor testing needs to close doors and windows, formaldehyde TVOC testing time takes about 60 minutes, cabinets, drawers and other small space about 3-15 minutes.

For long-term monitoring, the real-time data is unstable.  

Do not place the detector in the environment of high concentration of dust and high concentration of polluted gas for a long time.

Pay attention to fire/waterproof/dust/fall/sun-proof/moisture proof/mildew-proof and prevent severe shaking.

Children with electronic instruments or mental retardation should not move.

For long-term use, please place it in a safe area and store it properly, away from inflammable and explosive products.

Reference data for air quality assessment:

Feature:

1. Upgrade the indoor air quality monitor with built-in DART electrochemical sensor, which can accurately detect carbon dioxide (CO2), formaldehyde (HCHO), volatile organic compounds (TVOC) and particulate matter (PM2.5/PM10). 

2. This new model can provide real-time data and average value. It is suggested that you focus on the average value of each gas after testing, because the real-time data is unstable due to long-term monitoring.

3. Everyone needs to know the air quality of the place where you live. This air display has a LCD digital color screen, which is large and easy to read.

4. This air monitor is easy to operate, and only needs to press the function button. The whole page design makes it easy for everyone to read real-time readings, which is easy to carry. 

5. It can help us to detect the air quality of home, kitchen, bedroom, office, school, car, hotel, travel, camping, party, etc. especially babies, children and pregnant women.

6. HLW-100 air quality detector is a multifunctional intelligent household air quality monitoring equipment, which is not a professional testing instrument. The measured data can only be used as a reference for the change of domestic air environment. Meet the test range standard, CE standard and ROHS standard.

Instruction and tips:

1. Check whether the instrument is in good condition before use.

2. After starting up, the instrument can be tested and used only after the data is stable.

3. Formaldehyde TvoC detection needs 120 seconds of preheating and timing after startup, and PM2.5 PM10 detects data in real time.

4. The doors and windows of indoor testing need to be closed. The detection time of formaldehyde TVOC is about 60 minutes, and the small spaces such as cabinets and drawers are about 3-15 minutes.

5. Long-term monitoring, real-time data is unstable, please take the average value of monitoring data as the standard.

6. Do not place the detector in an environment with high dust and high concentration of polluted gas for a long time.

7. Pay attention to fire/water/dust/fall/sun/moisture/mildew to prevent violent shaking.

8. Children with electronic instruments or mental retardation should avoid touching it.

9. For long-term use, please keep it in a safe area and keep it away from inflammable and explosive materials.
