Temtop M2000 2nd air quality monitor adopts advanced sensor help you better understand the air quality level of surroundings. This multifunctional air pollution monitor can be applied in home, office, school, car, etc. With Temtop M2000 2nd air quality monitor, you can view the CO2, PM2.5, PM10, Particle Number, HCHO, Temperature and Humidity readings in real time.

Data Exportable:

As an upgrade version of M2000, M2000 2nd air quality monitor has developed a data export function that allows you to download all the data recorded for CO2, PM2.5, PM10, Particle Number, HCHO, Temperature and Humidity via USB cable.

Audible Alarm:

Settable alarm value for PM2.5, CO2, HCHO concentration. The air quality monitor will alert when the readings are out of the limit value you set.

Energy SavingMode:

The device will automatically turn off after 1 hour of no activity, or you can press and hold for 2 seconds to manually turn it off. Note: Auto off function is invalid in Histogram interface.

Zero Calibration:

Removing any trace from the electrochemical formaldehyde sensor, laser particle sensor, and carbon dioxide sensor, to provide the instrument with a baseline reading. Note: PM2.5 unavailable.


Rechargeable battery. Up to 6 hours long running time on a full charge. °C/°F switchable.

Q: Why is the data reading very high/over-range after the detector is turned on?
A: As being packed in ink printed package box over time may interfere with the sensor due to the remaining organic volatile residue inside the package. Therefore, after unpacking, please put the detector in a ventilated place to help accelerate its data recovery.
Q: Why is data reading unstable?
A: As airflow in the environment is changing, the distribution of organic matter concentration may be uneven. Temtop recommends trying again in low airflow areas.
Q: Why is the test result abnormal or below normal?
A:① Please check whether the air inlet or outlet has been covered or fluid is in.
②Gently shake the detector during detection to increase the interaction with surrounding air.
③The sensor may be not recovered. Please place the detector outdoors for ventilation.
Q: Can the calibration be accelerated if the detector is facing the outlet of air conditioner / fan?
A: No. The temperature difference or airflow speed at the air conditioner/fan outlet is relatively high, which may cause condensation or temperature changes on the sensor, affecting its detection performance. Please put the detector outdoors in a cool ventilated place.
Q: Why is the PM2.5 reading constantly changing?
A: As PM2.5 concentration in the environment is changing all the time not only due to environment factors like changes in airflow, humidity, wind direction and etc. but also due to common pollutant sources like smoking, cooking; exhaust emissions from vehicles, smoke from burning coal/chimneys/fumaces and etc. All these may influence the PM2.5 concentrations and give differences in the readings.
Q: Why is the HCHO reading inaccurate or overestimated at some points?
A: As Temtop uses a high-precision electrochemical HCHO sensor, its electrochemical reaction characteristics could also respond to other gases besides formaldehyde. This table lists the most common gases that interfere with relative sensitivities of HCHO sensor:

Interference Gas

Relative Sensitivity (%)

Carbon monoxide (CO)


Hydrogen (H2)


Ethyl alcohol




Sulphur dioxide(SO2)


Ammonia (NH3)
