CO2 Meter Full Range (0-100%)
This is our professional carbon dioxide (CO2) meter that stands out as the top-tier choice and offering a cutting-dual channel NDIR CO2 sensor. Designed to cater to the needs of professional industrial technicians who require CO2 detection capabilities beyond basic ambient readings and require the full volumetric detection 0-100% range of monitoring. It is an ideal solution for CO2 measurements in silos, tanks, storage rooms, fermentation processes, beer production, and various industrial processes. For those interested in a narrower range, we have the same model in 0-10% CO2 and 0-5000ppm CO2.
Note: The FD-90A-CO2 is a diffusive gas meter model, which means it does not have a built-in pump. If you want a forced air pump feature, you can purchase a separate pump option, or purchase the built-in pump CO2 0-100% version.
CO2 Meter (0-100%) Comparison Chart
We present a CO2 meter comparison chart several other models.
What is a CO2 Meter?
A CO2 Meter is a small handheld unit that is able to detect the CO2 molecules in the air and measure their concentration relative to the volume of other gases. A CO2 meter usually costs between $300 to $2000.
A CO2 meter gauges the carbon dioxide levels indoors, in a silo, incubator, closed space, or any environment one decides to place the meter. A CO2 meter incorporates a Non Dispersive Infra Red sensor which selectively tracks the CO2 concentration via gas absorption. These sensors employ and IR lamp source and a thermopile with a carefully tuned thin film bandpass IR filter.
Case Study 1:
CO2 Levels in Insect Control for Grain Storage
An interesting study looks at employing CO2 derived from biogas to control pest infestation in wheat grain storage.
Controlling pests in wheat storage is paramount. Post-harvest losses occur in harvesting, threshing, cleaning, storage, processing, and transportation. Insect infestation can damage food quality, affect human health, and create a breeding ground for microorganisms. Phosphine gas is currently widely used, but pest resistance is increasing due to poor sealing and inefficient use. Carbon dioxide (CO2) as a controlled atmosphere offers a potential alternative to traditional fumigants for pest control.
This study looked at the efficacy of used CO2 as as pest control during wheat storage. The study assessed bio-CO2 (≥98% CO2, ≤2% CH4) from a CBG plant as CO2 source for wheat storage. The study compared bio-CO2 and pure CO2 effects on Rhyzopertha dominica mortality, seed germination, and wheat quality.
It was found that bio-CO2 achieved 100% insect mortality in 1-5 days and pure CO2 in 4-8 days. The R. dominica population multiplied 3.9x in two months and 10.4x in six months in control grains.
What is the recommended frequency for calibrating my handheld CO2 monitor?
Our suggestion is to perform calibration every 6 to 12 months. The frequency of calibration directly influences the precision of your CO2 meter's readings. You have the option to utilize our CO2 gas calibration service or conduct self-calibration using a kit containing the following components:
Calibration Kit
Calibration Gas (CO2)
Calibration Gas Regulator (C10)
How long will the CO2 Monitor Last?
The advantage lies in the impressive longevity of CO2 monitors when compared to other gas sensors like electrochemical cells. CO2 monitors employ NDIR (Non-Dispersive Infrared) sensors, durable electronic components that generally remain operational for 5 to 15 years. Among these components, the infrared source tends to experience gradual degradation over time. Thus, an annual calibration is recommended to maintain precise and dependable performance.
Conclusion
- A CO2 meter measures CO2 concentration to help with insect control for grain.
- A CO2 meter is also known as a carbon dioxide monitor, analyzer, detector, or CO2 analyzer.
- CO2 meters are widely used in diverse labs, including government, private, and academic settings.
- Remember to calibrate your incubator's CO2 meter for precise results.
