Summary of Contents for EG AIR EGVOC-100
- Page 1 Multifunctional Air Detector User Manual Be sure to carefully read this user manual regarding use and keep it for future reference.
- Page 2 I. Introduction This product is a multifunctional air detector that detects Formaldehyde (HCHO), Total Volatile Organic Compounds (TVOC), and Particulate Matter <2.5 micron-sized particles (PM2.5) with clock and air quality record chart. As a professional and scientific air detection device, it combines advanced sensor technology with a built-in fan to allow real-time monitoring of formaldehyde (HCHO), total volatile organic compounds (TVOC), and PM2.5 on its digital LCD display.
- Page 4 Why measure TVOC and Formaldehyde? TVOCs are carbon-containing compounds produced by synthetic processes, materials, and organisms. Formaldehyde has suspected links to nasal cancer and lung cancer and emitted from many household materials. Most known carcinogens are synthetic organic compounds as they can interact with DNA to cause mutations/cancer.
- Page 5 If item is newly purchased or has not been used for long periods, it may accumulate gases from packaging that can affect detection results. In this case, place the device before use in fresh well- ventilated air for at least 20 minutes, leaving it unused during this period.
- Page 6 2. Allow device to fully start up by allowing TVOC counter to count to 0. 3. Place device in a CLEAN OUTDOOR AIR environment for 5+ minutes where there is no formaldehyde or TVOC. Putting the device outside for at least 5 minutes allows full circulation of outside air into the device. Putting the device outside longer may be even better.
- Page 7 8. Push the right > button twice to select "Back" and exit to the main screen. You will see that device has set the HCHO and TVOC readings as 0.000 mg/m You can confirm device has been calibrated after exiting to the main screen and seeing device reads 0.000 mg/m for HCHO and TVOC.
- Page 8 Why are there significant differences in HCHO and TVOC readings at different times? There can be large variations in formaldehyde (HCHO) and TVOC readings within a house on different days and in different rooms. The total volatile organic compound (TVOC) readings can vary by magnitude of 10 or more on different days.
- Page 9 Why is the TVOC reading 9.999 mg/m Make sure there are no fragrances, body odors, perfumes, smoke, aromas, detergent or cooking smells near the device as these all are benign sources of total volatile organic compounds (TVOCs). They will lead to higher TVOC concentrations and an elevated or 9.999 mg/m reading as the device is sensitive and the human nose is often exposed to TVOC concentrations far greater than 10 mg/m .
- Page 10 AIR LEVEL QUALITY AND GRADE When formaldehyde (HCHO) concentration is less than 0.080 mg/m and PM2.5 is less than 55, LCD screen displays Level as Fresh in green and air quality is fresh. When formaldehyde (HCHO) concentration is between 0.080 to 0.300 mg/m or PM2.5 is between 55 to 250 mcg/m , LCD...
- Page 11 Board recommends an “action level” of 0.1228 mg/m (0.1 ppm) and a “target level” of 0.0614 mg/m (0.05 ppm) or lower for homes. PM2.5 Level Interpretation According to the EPA, here are levels of PM2.5 or dust particulate matter measuring micrometers less considered...
- Page 12 when determining air quality grade. This is because hazard levels with TVOC are specific to the actual organic compound(s) in the air; some synthetic organic compounds are hazardous whereas many natural organic compounds are harmless. U.S. Green Building Council’s recommended healthy building level is 0.500 mg/m .
- Page 13 Many harmful or carcinogenic compounds are synthetic organic compounds that are easily inhaled into the body as they are “volatile” or easily evaporated at room temperature. Can you inform me how to convert mg/m to ppm for formaldehyde? For formaldehyde, At 760 mmHg and 20 °C, 1 ppm = 1.249 mg/m3 and 1 mg/m 0.801 ppm;...

TYPES OF INTERFACE (MENU) With the default Overall Interface, the time, battery level, air quality level, formaldehyde (HCHO) concentration, Total Volatile Organic Compound (TVOC), and PM2.5/10 concentrations are displayed. To access the Menu Interface, press the center button labelled Pressing the center button again allows downward selection within the menu in RED.
- Page 15 • System Setting You can set [OFF time] for time period before self-shutoff, [Version] for interface style, [Factory Settings] to reset device, and [Time Setting] to set the time and date. • Alarm Settings Default alarm threshold when alarm sounds is 0.10 mg/m .
- Page 16 or right button to (-) alarm threshold. Alarm will ring when HCHO level is exceeded. To turn off alarm entirely, press center button within Alarm Interface to highlight ON/OFF selection Blue. Press left button to turn alarm ON/Open and right button turn alarm OFF/Close. Press center button to exit to Menu Interface and “Back”...
- Page 17 • When LCD screen displays "Lowest power, please charge", device will turn off automatically after 3 seconds. Continuous air quality monitoring can be achieved by charging device with micro USB cable while monitoring and setting [OFF time] for time period of 2 days found under System Settings within Menu interface.

Questions and answers
can you download data from this system
does the EG Style Air Quality Monitor w/ PM2.5, TVOC, HCHO, Temp/Humid (B078ZS8RVL) have the capacity to download data. It indicates it can hold data over a 24 hour period
EGVOC- Is there possible that you help check the type of sensor for PM2.5 measurement? If it is laser, what type of laser? It is related to whether there is any license needed to use the equipment in SG.
The EG AIR EGVOC-100 uses a Laser Detection Sensor for PM2.5 measurement. The specific type of laser is not mentioned.
