How do you read a CO2 meter?
How do you read a CO2 meter?
For most products, the CO2 level is measured as a percentage of a volume of air either as a % or as parts-per-million (ppm)….Counting a Million Gas Molecules
- 1,000,000/1,000,000 = 100%
- 100,000/1,000,000 = 10%
- 10,000/1,000,000 = 1% or 10,000ppm.
- 1,000/1,000,000 = 0.1% or 1,000ppm.
- 400/1,000,000 = 0.04 or 400ppm.
How does a CO2 meter work?
NDIR CO2 sensors monitor and detect for the presence of carbon dioxide based on the absorption of infrared light at a specific wavelength. An NDIR sensor comprises an infrared source, a light tube, a bandpass filter, and a detector. The electronics then measure the absorption of the characteristic wavelength of light.
What should my CO2 level be?
Test results. The normal range for CO2 is 23 to 29 mEq/L (milliequivalent units per liter of blood). The blood test often measures blood pH along with CO2 levels to further determine the cause of your symptoms. Blood pH is a measurement of acidity or alkalinity.
Are CO2 meters accurate?
The TIM10 CO2 meter has an accuracy of ±50ppm and ±5%, so at a reading of 846ppm, the actual amount of CO2 could be between 796-896ppm (50ppm > 5% of 846ppm). Since the 2 sensors accuracy ratings overlap between 796ppm and 808ppm, you can say they are both correct within their rated accuracy.
What is an unsafe CO2 level?
The American Conference of Governmental Industrial Hygienists (ACGIH) recommends an 8- hour TWA Threshold Limit Value (TLV) of 5,000 ppm and a Ceiling exposure limit (not to be exceeded) of 30,000 ppm for a 10-minute period. A value of 40,000 is considered immediately dangerous to life and health (IDLH value).
What is the purpose of the Tim10 CO2 monitor?
Product description. The TIM10 CO2 Monitor lets you quickly, accurately, and inexpensively test CO2 levels around your home. Move it from room to room to test CO2 levels in your house. It can reveal if your home’s heating, ventilation, and air conditioning system is operating properly. High CO2 levels indicate inadequate or closed return air ducts.
How does the Tim10 work?
The TIM10 Desktop CO2, Temp, & Humidity Monitor continuously shows carbon dioxide, temperature, and relative humidity levels so you can monitor the quality of air in your home, office or indoor greenhouse. Just plug it in – the TIM10 turns on instantly, is self-calibrating, and is designed to last for years.
What is the range of the CO2 and temperature measurements?
Specifications CO2 Range: 0 – 10,000 ppm CO2 Accuracy: ± 70ppm ±3% reading value Temperature Range: +14 to +140F (-10 to +60C) Temperature Accuracy: ±0.9 F (±0.6 C) Humidity Range: 20-99% non-condensing (CO2 cannot be read under 20% RH) Humidity Accuracy: ±5% RH Display: Clock, Calendar, Alarm, Temperature, Humidity and CO2
