FNIRSI SFD-02 is an advanced 4-in-1 indoor air quality meter that measures formaldehyde (HCHO), TVOC, humidity and air quality index (AQI) in real time. It combines high-precision electrochemical and semiconductor sensors, active ventilation, a clear 2.4-inch HD touch screen, smart alerts and analytical functions. It is a complete tool to protect your health at home, in the office, in the car and in renovated or rented apartments.

Laboratory-grade accuracy in a home monitor

At the heart of the device is a highly sensitive electrochemical sensor specially designed for selective detection of formaldehyde. Advanced interference filtering ensures accurate and stable measurements even at very low concentrations, so you can be sure that you are responding to a real threat, not random fluctuations.

Constant TVOC monitoring – detects hidden sources of pollution

The FNIRSI SFD-02 also monitors TVOC – volatile organic compounds emitted by furniture, paints, adhesives, detergents and new finishing materials. This allows you to quickly identify problematic objects or rooms and effectively improve air quality.

Stable measurements due to forced air flow

The integrated active air intake system eliminates the influence of external drafts and uneven air flow. The result? A constant air supply to the sensors and more accurate readings, regardless of where the device is placed.

Clear 2.4-inch HD touch screen – everything is clear at a glance

The large tempered glass touch screen clearly displays: HCHO concentration, TVOC, humidity, air quality index, risk assessment, date, time and battery charge status. Operation is intuitive and convenient even for children and seniors.

Real-time risk assessment – you know when to react

Thanks to the powerful FNIRSI SFD-02 processor, the device instantly interprets the data and presents it in the form of an understandable air quality rating (excellent / good / weak / average / strong). You don’t need to analyze the numbers – the device itself shows you whether the air is safe.

Automatic audible alarm – safety you can hear

When the formaldehyde or TVOC levels exceed safe values, the monitor automatically activates an audible alarm. This ensures that you don’t miss the danger, even if you’re not looking at the screen.

Different household members, different needs – individual safety thresholds

The device offers special settings for children, pregnant women and the elderly, taking into account their greater sensitivity to pollution. This is a real benefit for families who want to take care of the most vulnerable members of their household.

Measurement history showing more than one reading

FNIRSI SFD-02 records historical data and presents it in the form of easy-to-read curve graphs, allowing you to monitor trends and evaluate the effectiveness of ventilation or air purification.

Smart “smiling guard” – visual warning in sleep mode

In sleep mode, the screen displays changing facial expressions – the worse the air quality, the “sadder” the face, and in case of high concentrations, audible warnings are activated. This is a simple but very clear warning signal.

Formaldehyde removal calculator – plan your actions without guessing

The integrated formaldehyde reduction calculator helps you estimate the time and cost of pollutant removal, taking into account the size of the room, HCHO concentration and the selected method (ventilation, activated carbon, photocatalysis). It is a practical tool for making real decisions.

Mobility and convenience – 1000 mAh battery and charging station

The integrated 1000 mAh lithium battery and wireless charging station ensure long operation and convenient charging. You can easily move the monitor from one room to another, take it with you in the car, or use it when receiving an apartment after renovation.
