Features:
- Detection resolution enhancement. The jitter is below 150uv - Modular implementation of parts of parts - Data refresh speeds up 1 times - Support TF Card (32GB) - Open 16 - scale extended serial instruction to facilitate the two development - Upgrade imported 18650 standard steel shell battery, 3350mAh extension 50%

After the AIR MASTE R has detected the pollution exceeding the standard, the system will automatically judge and give it
perhaps
To prompt you to exceed the standard value.
The relative cross interference characteristics of formaldehyde were: CO 1%, H2S no data, H2 0.1%, SO2 12%, NO2 no data, NO no data, CL2 -3%, C2H4 no data, NH3 0%, CO2 0%, methanol ethanol 50%, phenol 7%, water va por 0%.When detecting formaldehyde, please stay away from alcohol, vinegar, and other volatile substances to avoid cross interference. It is recommended to test in the daytime, without cooking.
Environmental Reference Limit:

| PM2.5 | 50ug/m3 | <10ug/m3 |
| PM10 | 50ug/m3 | <10ug/m3 |
| HCHO | 0.1mg/m3 | 0.0mg/m3 |
| VOCs | 0.6mg/m3 | <0.2mg/m3 |
| CO2 | 1000ppm | <450ppm |
| Tempa?| | 23 degrees Celsius | N/A |
| RHa?| | 40%~60% | N/A |
Use Note:
- Stand upright and put on the table. If you do not use the right hand of the machine, you can hold the left hand with your left hand. Otherwise, it will affect the temperature and the formaldehyde.
- Do not put it on the bed.
- For the first time, you need to open the machine for 60 minutes, and then use it for 5 minutes each time.
- The test of formaldehyde needs to close the door and window in advance for 12 hours to measure the formaldehyde (national standard).
- Battery power is the Yellow scintillating LED below the screen flicker 4 full power, no battery version, often show full power.
- Do not blow excessive pollution into the sensor, easy to cause electrochemical pollution overload, the sensor will be very difficult to restore 0 points.
- (this situation requires manual correction of 0 points)
- Dust, dust weather (Sha Li) and other non haze weather will interfere with the laser detector. The PM value that may be measured at this time will be reduced.
- The version of the lithium battery does not short circuit the electrode on both sides of the battery. Please do not put it in an environment of high heat and full of conductors.
- Away from the silicon va por, shampoo etc..
The first time to start the machine, because there are some peculiar smell in the machine package, it will affect the numerical value of the boot. It needs to start for 1 hours, the smell of the probe will be distributed, and then do the test.Do not receive the machine immediately after the probe 0. It is very important to fully open the machine for preheating.
