Formaldehyde monitor

Introduction to air quality monitors

VOC monitor measures the concentration of Formaldehyde (HCHO) and VOC in the air. VOC is a cluster of a volatile organic compound group of gases. Formaldehyde gas is a part of VOC. This particular monitor is more sensitive to Formaldehyde. However, it can detect other VOC gases as well. Formaldehyde is a naturally-occurring organic compound with the formula CH2O or HCHO. In the form of gas, Formaldehyde is colorless and flammable. It has a characteristic pungent, irritating odor. The monitor measures this gas from 0-5ppm with a resolution of 0.1ppm. The sensor accuracy is within 15% for even low values of concentration. Many times, people are unaware of the ill effects of Formaldehyde pollution.

Technical details Formaldehyde/VOC sensor

• VOC gas measuring range: 0.000 to 5.000 ppm
• Accuracy: ±5%
• Resolution: ≤ 0.1 ppm
• Long term stability: ±0.5 %rH
• Operating temperature: 0°C – 50°C
• Operating humidity: 0 to 100 %rH (relative humidity)
• Following is the relative sensitivity for various different vapors
– LPG / CNC, highly sensitive
– Formaldehyde (HCHO), highly sensitive
– Benzene, Toluene, moderately sensitive
– Gasoline and petroleum products, highly sensitive

FORBIX SEMICON produces 4 varieties of Formaldehyde/VOC monitors:

  1. FBXYF3: handheld rechargeable battery operated
  2. FBXYF3T: lemon green / bluish white display (tabletop)
  3. FBXYF3DL: Formaldehyde/VOC monitor with data logger
  4. FBXYF3TR: Formaldehyde/VOC monitor automatic control transmitter/receiver

Important note:
• Formaldehyde/VOC monitor gives a collective reading of TOTAL volatile organic
compound (TVOC) concentration in the air

• The gases need to reach to the sensor unit to show the concentration accurately

Air Quality Index (AQI) values:

• GOOD: 0.000ppm < display value < 0.050ppm (breathing air quality is healthy)
• NORMAL: 0.050ppm < value < 0.080ppm (air purifier is preferable; might cause breathing troubles (like coughing, sneezing if exposed for a prolonged duration)
• POOR: 0.080ppm < value < 1.200ppm (not good for health. Will cause health hazard if continuously exposed under these breathing conditions)
• ALARM: 1.200 < value < 5.000ppm (not fit to breathe even for more than 10-15 minutes. Recommend to turn
off the monitor in such cases)

[Note: No amount of VOC is good for health]

Health effects of inhaling Formaldehyde

Although the short-term health effects of Formaldehyde exposure are well known. Less do people know about their potential long-term health hazards. Moreover, people who are often exposed to mild levels of HCHO for prolonged periods of time. Hence, they have shown adverse health effects.

Henceforth, it becomes extremely essential for people to know Formaldehyde concentration in air. FORBIX SEMICON HCHO monitor unit helps to do so.

Why is Formaldehyde checking so important

Formaldehyde is one of the major constituents of polluted air. Studies show that Formaldehyde pollution is a major cause of long term health hazard. Especially in the modern city and furnished rooms, this is a concern.

With Formaldehyde levels exceeding 0.1 ppm, some individuals may experience adverse effects. Such as respiratory problems, burning sensations in the eyes, nose, and throat. Direct exposure causes coughing, wheezing, nausea, and skin irritation. Studies show that some people are very sensitive to Formaldehyde. Whereas, others have no reaction to the same level of exposure.

Where is Formaldehyde present

Formaldehyde in form of Formalin is popular in hospitals and dispensaries. People use it for air sterilization purpose. Especially to neutralize viruses and bacterias in operation theaters (OT), in hospitals

Formaldehyde finds its presence in household furniture. Cabinets moldings, particle wood, shelving, stair systems, flooring, and many other household furnishings. Especially furniture made up of particle wood has a high concentration of HCHO

In textile industries, Formaldehyde is a major component to bind dyes. Many pigments to stick on to the fabrics because of HCHO component
