1. Introduction
The Temtop LKC-1000S 2nd generation Air Quality Monitor is a professional device designed to provide comprehensive insights into your indoor and outdoor air quality. It accurately measures key air factors including particulate matter (PM2.5 and PM10), formaldehyde (HCHO), humidity, temperature, and the Air Quality Index (AQI).
Equipped with pre-calibrated Dart electrochemical sensors and an industrial-grade laser particle sensor with a lifetime of up to 20,000 hours, this monitor ensures accurate and stable measurements. Its user-friendly design features a large TFT screen with a 6-level colorful health indicator for easy readability.

Before first use, fully charge the device using the provided USB charging cable. Connect the cable to the charging port on the device and a compatible USB power source. The battery indicator on the screen will show charging progress.
3.2. Initial Calibration
For accurate readings, it is crucial to perform an initial calibration. Place the monitor outdoors in a fresh air environment for approximately one hour before its first use. This allows the sensors to stabilize and calibrate to baseline outdoor air quality levels, ensuring reliable measurements when used indoors.
4. Operation
4.1. Powering On/Off
- To turn on the device, press and hold the power button (central button with a circle and vertical line) until the screen illuminates.
- To turn off the device, press and hold the power button again until the screen turns off.
4.2. Interpreting Readings
The large TFT screen displays various air quality parameters. The device uses a 6-level colorful health indicator to help you easily understand the air quality at a glance, based on EPA standards.
Figure 6: Air quality health level indicator based on EPA standards.
- PM2.5 / PM10 / Particles: These screens show the concentration of particulate matter and the number of particles per liter. Use the dedicated PM2.5 button to cycle through these displays.
- Formaldehyde (HCHO): The HCHO button displays the concentration of formaldehyde.
- AQI / Temperature / Humidity: The AQI button cycles through the Air Quality Index, current temperature, and humidity levels.
4.3. Important Usage Notes
- Do not cover the vents of the detector.
- Do not let fluff or excessive dust enter the detector, as this may damage the particle sensor.
- Avoid using the detector for a long time in a humid environment or strong irritating odor environment to ensure measurement accuracy.
- Avoid measuring visible particles like heavy smoke or pollen, as this can damage the sensor and lead to inaccurate readings. The device is intended for particles 10 micrometers or smaller.
5. Data Management
The Temtop LKC-1000S 2nd offers a convenient data export function, allowing you to track and analyze air quality trends over time. The device's memory is capable of storing at least 3 months of continuous data recording.
5.1. Data Export
To export data, connect the monitor to your computer using the provided USB cable. The device will appear as a removable storage device, and you can access the stored data files for analysis (e.g., in spreadsheet software).
