Best Temtop Indoor Air Quality Meters in 2026

[7-IN-1 Multifunctional]: This professional air quality monitor measures CO2, PM2.5, PM10, particle numbers, HCHO, temperature and humidity.

[Advanced Built-in Sensor]: Equipped with Temtop Laser PM2.5 sensor, SenseAir NDIR CO2 sensor, Dart electrochemical HCHO sensor and Sensirion temperature and humidity sensor.

[Audio Alarm]: The monitor will automatically alert through the built-in buzzer (MUTE function available) and the indicator light when the air pollution levels get too high.

The economical 5-in-1 air quality detector use highly accurate and professional sensors to measure PM2.5, PM10, particle, HCHO and AQI.

By using our latest 3rd generation Temtop laser particle sensor and optimised PSO algorithm, it makes particle measurements become more accurate and stable and enhanced its sensor life up to 20,000 hours.

The pre-factory calibrated electrochemical sensor enhanced its accuracy and capturing formaldehyde molecules more precisely.

ALL-IN-ONE RELIABLE AIR QUALITY MONITOR. The most advanced monitor measuring particulate matter (PM2.5 and PM10), formaldehyde (HCHO), VOC (airborne chemicals), humidity, temperature, and AQI. Tested by AQMD, R2 up to 0.999.

DATA EXPORT AND HISTOGRAM. The histogram function can reflect the changes on PM2.5 directly for the latest 12 hours, helping you to keep track of the air. Export data to gain full visibility and analysis into 7 key indoor air factors. Memory allows at least 3 months of continuous data recording.

PRE-CALIBRATED SENSORS. The pre-calibrated Dart electrochemical sensors will accurately capture formaldehyde molecules accompanied by the detection function covering a wide range of organic pollutants.

UPGRADED SENSOR: Adopting Temtop second-generation PM2.5 particle laser sensor, directly transform the PM2.5 & PM10 concentration into visual data and colorful health level indicators, providing an effective safeguard for you and your family.

PROFESSIONAL SENSOR: Advanced industrial-grade sensor offers more than 20,000 hours lifespan. Combined with the unique particle swarm optimization algorithm, it makes particle measurement more accurate and stable.

DATA GRAPH: Large storage capacity to store and display the data of the past 12 hours, check the air status via the histogram and track the trend of air quality for the specific time period.

PORTABLE DUST MONITOR. Adopts the Mie-scattering principle to detect detect the concentration of 5 different particles, including PM1, PM 2.5, PM4, PM10 and TSP.

CLEAR DISPLAY AND DATA INTEGRATION. Large display for viewing particle data, you can choose a specific channel as the main view. Built-in 2,000,000 sets of data storage capacity and can be directly exported to your U disk.

RELIABLE RESULTS. Adopts 2.83L/min (1 CFM) pump suction laser particle sensor module, a more stable flow rate brings a more accurate measurement of particulate matters.
