Air Quality Monitors

Indoor Air Quality Monitors

Air quality monitors has become an essential device in modern homes and offices. The air quality monitors, measures the pollution level of the air that we breathe. It quantifies the measured value of pollution in human understandable figures. In case of measurements are alarming or high, necessary action needed to clean or purify the air. FORBIX SEMICON produce a wide variety of air quality monitors.  Nowadays, air pollution is everywhere.  In your house, office, factory, hospital, dispensary schools, colleges or even public places.  A clean and healthy breathing air is mandatory to maintain disease free human body. The air quality monitors have elegant looking bright LCD screen. The measurement values are visible in dark or illuminated room.

Air quality monitors

  • Dust monitoring system PM2.5
  • Carbon dioxide (CO2) meter
  • Combined dust PM2.5 + CO2 + temperature + humidity
  • Formaldehyde meter(HCHO)
  • VOC monitoring
  • LPG alarm and sirens

Dust monitor (for PM2.5)

The dust monitoring device measures the particulate matter for up to 2.5 microns (μm). This unit is suitable for homes and offices to check the presence of PM2.5 particles suspended in the air. The readings are in μg/m3 unit. For clean rooms the range should be below 50-60 μg/m³. If the readings show more than 100-150 for longer durations, then it is time to use and air purifier. The dust monitoring device can measure up to a level of 1400μg/m³. Beyond 1000μg/m³ the monitors should turned off.

The dust monitoring device comes in two colors of display, viz. lemon green and bluish white.  The unit operates on a optical sensor matter scattering principle. Air flows through the vents on the left side through convection. IR light projected on the flowing air scatters. The amount of scattering is proportional to the suspended particles. An averaging value of the scattering shows the air pollution level.

Carbon dioxide (CO2) meter

Carbon dioxide is one of the major source of invisible pollutants in closed rooms. Whether it is house or conference rooms in offices.  Carbon dioxide is a odorless and colorless gas. People should not inhale CO2 for long duration. Doing so can cause breathing troubles, nausea and short breathness. If a room occupied for more than 20 minutes, the CO2 level in the room increases. With everyday pollutants and vehicles increasing modern cities the readings are even worse. Inhibiting, CO2 increase is a major concern for countries all across the world. The CO2 meter also used for plantation and agro industries. Where the Carbon dioxide level needs to be under control. Food industries need continuous CO2 monitoring and alarm.  CO2 measures from 200 – 10,000 ppm.  The meter also measures temperature (in °C) and humidity (in %rH)


Dust (PM2.5) and carbon dioxide (CO2) combined meter

A combination of dust and carbon dioxide meter serves as a dual monitoring device. Besides, it also shows temperature and humidity values. Both PM2.5 and CO2 are the major source of indoor pollutants. Quantification of level is visible on the LCD display as GOOD, NORMAL, POOR and ALARM. The monitoring system used by factories, offices, hospitals, and even residential people. CO2 measures from 200 to 10,000 ppm. PM2.5 from 20 to 1400μg/m³. Temperature from 0 to +50 °C. And humidity from 0-100%rH.

Formaldehyde meter

Formaldehyde is a major source of pollutants in AC ducts, and clean rooms. Moreover, residual quantities of Formaldehyde (after disinfection) inhaled causes problems on long term. Formaldehyde. chemical formula (HCHO) is a pungent smelling gas. Once inhaled it causes irritation in eyes and respiratory system. This chemical used in particle wood for furnitures etc. The meter shows readings from 0.001 to 5.000 ppm. Therefore, this meter meter can detect even minute traces of the gas suspended in the atmosphere.

VOC monitoring device

VOC monitor, as the name suggests, measures VOC gases in the atmosphere. Volatile organic compounds (VOC), as the name suggest is a combination of various gases. Moreover, a total VOC (TVOC) count is a collective measurement of the volatile gases. Compounds like Benzene, Toluene, Xylene, LPG, petroleum products etc. constitute VOCs. At homes and offices, VOCs found in paints, dye chemicals, AC ducts. Some compounds in liquid form have a pungent smell while others have a pleasant odour. But a common factor among all these compounds is that, they are volatile in nature. Hence, it mixes with the atmosphere very easily and rapidly.

VOCs if inhaled for longer duration of time, cause irritation in eyes. It also causes respiratory disorder if exposed for many hours to humans. Therefore, VOC monitoring device helps in detecting even small traces of VOC in the air we breathe. Hence, after checking the readings, (if high), it is possible to take corrective action.
