The MYCO2 is a high performance infra-red gas sensor, designed for monitoring environmental CO2 in protected crops and demand controlled ventilation.
MYCO2 is a robust, low cost CO2 monitor, housed in an IP65 rated enclosure against the ingress of water and particulates. The monitor operates on a diffusion/convection principle and therefore no sampling pump is required.
This monitor can easily be wall-mounted.
For many years, Edinburgh Sensors has manufactured infra-red, dual wavelength sensors with a single optical path and without any moving parts. As a result, the sensor is highly gas specific, and insensitive to other gases and water vapour.
This ensures long term stability and accuracy over extended periods, removing the need for frequent re-calibration.
The MYCO2 sensor can be customised to suit specific applications, placing the design control in the hands of the system designer. The user selectable functions include linear analogue output options, alarm function software and automatic temperature correction.
The MYCO2 sensors are aspirated by a combination of diffusion and convection within the sensor head. This gas sampling method is silent, reliable and provides a fast response time. Convection is used to circulate gas between the sensor head and the diffusion cell with gas exchange occurring, by diffusion, at the surface of the diffusion membrane. Since the gas in the cell circulates within a closed system, all optics are protected from the ingress of dust. No additional pumping or filtering of the gas is necessary.

From fermentation through to distribution, Carbon Dioxide is one of the most common hazards to health in breweries, cellars and drinks outlets.
It is also the fourth most abundant gas in atmosphere; Long term exposure to only 0.5% volume represents a toxic health hazard.
Concentration greater than 15% volume can lead to death.
CellarSafe has been specifically designed
to warn personnel of these hazards and features both long life sensors and remote warning panels (whcih can for example be installed behind a bar as well as at the entrance to the cellar).

Novel infrared measuring system for CO2
With an infrared sensor (IR sensor) specifically for carbon dioxide.
The infrared measuring system detects the carbon dioxide content of the ambient air fast and precisely. It contains a novel infrared measuring system functioning basically like a conventional two-beam photometer.
However, since material and construction of the sample cell are novel, and the measured signals are evaluated and processed according to a new digital algorithm, the infrared measuring system is light-weight, compact, in normal applications maintenance-free and long-term stable but nevertheless affordable.
The infrared measuring system detects the absolute carbon dioxide content of the ambient air (partial pressure), monitors itself constantly and signals malfunctions of its hard and software. The whole measuring range is linear.

The GMT220 transmitter series is designed for a wide range of industrial carbon dioxide applications including greenhouses, fruit storages, safety alerts and demand-controlled ventilation in mushroom farms, livestock husbandry and parking garages.
The GMT220 transmitters measure carbon dioxide in harsh and humid environments. The housing is dust and waterproof to IP65/NEMA4. The materials have been chosen for extended corrosion resistance.
The GMT220 transmitters are easy to use and install. The transmitters have a modular structure which includes a separate mounting plate for easy installation.
Interchangeable probes facilitate field maintenance. The probes can simply be replaced with newly calibrated ones, or with separate probes that are only used as a reference for calibration checking. This minimizes downtime and eliminates the need for expensive calibration equipment.

Besides pH and dissolved oxygen measurements, reliable monitoring and control of the CO2 partial pressure is important for successful fermentation. The oxidation of carbohydrates to CO2 water results from aerobic respiration. METTLER TOLEDO's new CO2 measuring system is specially designed for in-situ measurement into a bioreactor and therefore "registrates" exactly the same partial pressure as the cell.
METTLER TOLEDO offers a wide range of different measurement systems for very specific requirements in different industries consisting of sensors, housings, transmitters, services and fulfills all high quality requirements.

The LED based CO2 NDIR sensor is a fast response, low power NDIR CO2 sensor. It uses patented Indium Antimonide technology to produce a solid state source/detector pair. This gives a fast response to changes in gas concentration, and high immunity to ambient light/heat sources.
Carbon Dioxide (CO2) is measured by recording changes in the transmission of mid IR wavelengths around the carbon dioxide absorption peak at 4.26um.
The C20 is fully solid state, using an advanced mid IR LED and photodiode pair.
This eliminates the need for heated filaments entirely.
This sensor produces a temperature compensated, linearised output via a serial line, and is extremely simple to integrate into microcontroller based instruments.

The Alphasense patented carbon dioxide sensor is a world first in CO2 monitoring:
Requires no power
Operates at room temperature
One sensor measures from 500ppm to 95% CO2
Small size
Low cost
Simple interfacing
Using the potentiometric measuring principle with our patented silver halide solid state electrolyte, this sensor does not have the high power requirement or high price tag of NDIR technology. This sensor is ideal where low cost and low power are critical for CO2 measurement.
This sensor is the result of seven years of research and development, and this work continues. While not as accurate as NDIR, and not suitable for IAQ measurements, this sensor is ideal for safety alarms, combustion gas monitoring and high CO2 process monitoring.
