Guide To Purchasing A Carbon Dioxide Transmitter

carbon dioxide transmitterAre you worried about Carbon Dioxide levels in your home or in buildings that you maintain? If you have been considering the purchase of a Carbon Dioxide transmitter then today is your lucky day. In this article we are going to talk about why such a transmitter is good to have and advise you in regards to some excellent models that are available so that you can get a sampling of what is out there. Let’s take a moment and talk about Carbon Dioxide transmitters.

Why get a CO2 transmitter?

Colorless, odorless, and dangerous in high concentrations, Carbon Dioxide occurs naturally but is certainly something to monitor. Normally you are going to encounter it in a natural concentration of 400ppm or about .04%. Now, when we breathe in Oxygen we exhale Carbon Dioxide and it mixes with the air. No problem. However, in small, enclosed places where there are a lot of people the effects become much more noticeable, inducing problems with concentration, fatigue, or worse. A CO2 transmitter can detect when concentrations become baleful at the same time that it detects temperature shifts relative to the concentration of Carbon Dioxide. This is the secondary reason why you would want a CO2 transmitter. With those temperature shifts your energy bill is directly impacted, and so investing in a CO2 transmitter is a sensible way to make sure that you aren’t wasting money with environmental control when a building or area is unoccupied. It just makes good sense.

Where would one acquire a Carbon Dioxide transmitter?


We’re glad that you asked. We’ve collected an assortment of different Carbon Dioxide transmitters that you can take a look at and decide if they might be a good fit for you. We’ll list some models here, advise you on their features, and the rest is up to you. Let’s take a look at some popular models.

Dwyer Series CDTcarbon dioxide transmitter

Our first entry is the Dwyer series CDT Carbon Dioxide transmitter. This model  employs a beam of dual length NDIR (Non-directional infrared) sensor to help ensure the accuracy in CO2 detection in both occupied and unoccupied buildings. It further employs digital barometric pressure adjustment so that it can calibrate the sensor while it is actively in use. While it comes with buttons standard for adjustment you can order the series CDT in non-button configurations should you desire. The unit also measures direct unfiltered light intensity so that this does not modify the accuracy of the unit when it comes to CO2 detection. This unit is a great choice for Manufacturing plants and Hospitals which will be occupied 24 hours a day.

Dwyer Series CDTR

carbon dioxide transmitterOur second entry is the Dwyer series CDTR and it’s got a few extra features that make it handy. This unit measures CO2, temperature, and relative humidity. Beyond this, it uses the same beam technology as the CDTR and baromet4ric pressure field adjustment but as this unit can account for relative humidity it is a good fit for a wider range of buildings. Examples of a good use for this Carbon Dioxide transmitter include Schools, office buildings, hospitals, and a number of other building types where demand control ventilation is required.  With this model, a Digital Intelligence Temperature Compensation Algorithm is also employed in order to reduce the potential of errors from self-heating effects that can occur from wall mounting and it also has physical lockout features which may be employed to prevent tampering

Dwyer Series CDWPcarbon dioxide transmitter

Our third entry is the Dwyer series CDWP Carbon Dioxide Transmitter and this model is a bit more specialized, being an ideal fit for agricultural, industrial,animal husbandry, HVAC mechanical rooms, and various other indoor environments.  Note the housing on this model, it is IP54 aluminum, which means

“Capable of withstanding a 168 hour salt spray test.”

that it is designed for much harsher environments (capable of withstanding a 168 hour salt spray test) than the previous two models that we have showcased, while still employing single beam dual wavelength non-directional infrared technology for readings which gives it a high level of accuracy compared to the Automatic Baseline Correction Methods. This unit also features universal outputs that make it useable for the management of any type of building.

Dwyer Series CDTV

carbon dioxide transmitterOur fourth entry not only detects Carbon Dioxide levels but it also detects volatile organic compounds. Where this comes in handy is that one can detect fumes that should be lowered at times when occupancy is low in a building. This unit can save you energy funds by helping to determine when air conditioned air should be lowered. This unit is ideal for hospitals, commercial buildings, and schools and it provides HVAC management in such locations as well as fume management as needed. Ventilation levels are calculated with this unit through ASHRE occupancy based VRP algorithms and it also features the single-beam dual wavelength technology of the other units for extreme accuracy in determining the Carbon Dioxide levels in the location where you have installed it.

Some final words on Carbon Dioxide Transmitters

In this article we have described the benefits of using Carbon Dioxide transmitters in order to ensure that Carbon Dioxide levels are safe in buildings, office spaces, conference rooms, and other locations of your choosing. We have also advised how this is a money saving, lessening the amount of energy wasted  by proactively measuring the Carbon Dioxide and even the volatile organic compounds for fume management. If you are interested in any of these items we hope that you will check out the provided links in order to read more about this technology. It really does make good sense!
