9-in-1 Multifunction Air Quality Monitor
The more you know, the less you have to guess.
The MT419 is Gold-Pick's flagship 9-in-1 air quality monitor, measuring CO₂, temperature, humidity, light level, TVOC, barometric pressure, PM2.5, PM10 and HCHO/O₃ to meet smart buildings' need for complete insight into the indoor environment.
Its high-precision sensing module displays and transmits multiple indicators in real time, helping property managers and design teams identify pollution sources, optimize ventilation strategies, and save energy and cut carbon. It supports system integration, remote monitoring and data analysis, and can connect to BAS, energy management systems or cloud platforms. Ideal for office buildings, shopping malls, schools and healthcare facilities.

9 Integrated Sensors Measure a Wide Range of Conditions
* Only the MT419 series includes ozone (O₃) and formaldehyde (HCHO) sensors
CO₂CO₂ concentration, to judge whether ventilation is sufficient
PM2.5 / PM10Particulate matter, an indicator of air pollution and smoke
TVOCVolatile organic compounds
HCHO / O₃Formaldehyde and ozone (MT419 series)
TemperatureTrack ambient temperature in real time
HumidityToo high or too low affects comfort and health
LightBrightness data to check lighting conditions
Barometric PressureMeasures and records atmospheric pressure
PIR activityPassive infrared detection of human presence and activityHigher Accuracy, Stronger Interference Resistance
- Improved Insulation Design Temperature and humidity sensors are isolated from the operating chip to prevent errors and achieve higher accuracy.
- Superior Interference-Resistant Sensors The HCHO sensor provides more stable readings and is especially resistant to alcohol interference.
Optional 4.2-inch E-ink display
The larger the E-Ink display, the more information it shows; the MT408/MT419 present real-time environmental data in multiple display styles.
MT408 / MT419
With E-ink display · More interactive information on screen
MT408L / MT419L
No E-ink display · Longer battery life
Multiple display styles · Switchable light/dark mode
