CO2 controllers and testers

Large display continually monitors the primary IAQ (Indoor Air Quality) parameters: Air Temperature, RH, CO2.

These Indoor Air Quality (IAQ) monitors have large easy-to-read displays that continually present primary IAQ parameters: Air Temperature, Relative Humidity (RH), CO2 (carbon dioxide). IAQ monitors are ideal for observing indoor air quality in crowded public spaces with potentially high levels of CO2 such as offices, factories, classrooms, hospitals and hotels. These units recall min/max CO2 levels and provides visual alarms for maximum CO2 threshold. Automatic Baseline Calibration (ABC) and maintenance free NDIR (non-dispersive infrared) CO2 sensor ensure long-term accuracy, stability and reliability. Units come with an AC adaptor and will stand on a desk-top or wall mount.

Demand for quality indoor air continues to increase as we are spending more time indoors than ever before. IAQ issues can be complex due to the diversity of indoor environments. Poor air quality may cause tiredness, inability to concentrate, and even illness (i.e., Sick Building Syndrome).

To address problems caused by poor IAQ, national and local governments have developed guidelines for acceptable indoor air quality. Assessing indoor air quality in buildings begins with IAQ investigations using professional grade measuring instruments as the first step in creating a healthier work environment.

 Carbon dioxide (CO2) is a gaseous component of the earth's atmosphere.

The concentration of CO2 in natural ambient air is about 0.04% or 400ppm. With each breath, humans convert oxygen (O2) into carbon диоксиде which is invisible and odorless, an increased CO2-content makes is apparent because humans will notice increased fatigue and reduced concentration. In rooms with high occupancy such as conference rooms and theatres, negative effects become all the more evident.

CO2 Regulator with Flow Meter - Features an accurate, easy-to-adjust CO2 flow meter that supports 0.5 to 15 cubic meters per hour, a preset regulator that needs no adjustment, and a solenoid valve.

Each CO2 regulator also comes with a tank pressure gauge, easy-to-read flow meter and power cord. This regulator also works with any 120V device. After installing the CO2 regulator, simply add the necessary pipes to distribute the CO2 evenly throughout the room. If you are using it without a digital CO2 controller, you will need to use a timer. This regulator comes with a 3-year full warranty.

Includes:

• Range: 0.5 to 15 square meters per hour
• Preset regulator
• Easy to read flow meter
• Solenoid valve
• Power cable
• Tubes sold separately
• Works with 220V and any 120V device

Digital CO₂ Controller is an easy-to-use controller for measuring and maintaining CO₂ levels in your greenhouse or growing room: large digital LCD screen for real-time ppm, day, hour, minute, alarm levels, etc. This screen is divided into zones, which make it much easier and faster to find the readings of the parameters.

Dozer machine

Works with CO2 tablets . Place CO2 tablets in the slots in the machine and set the interval at which the machine releases them into your tank.

T-Micro CO2 Controller 

The T-Micro CO2 Controller is the smallest CO2 controller from the TechGrow range. This device is by far the best in its category, due to the complete digital technique.

You can use the T-Micro CO2 Controller in any room. It automatically turns the CO2 source on and off. The external CO2 sensor with light sensor enables automatic switching between day and night settings.

The T-Micro CO2 Controller is adjustable from 300 to 2000 ppm and performs a measurement every second. Its display shows actual values, including setpoint and hysteresis, and the indicator LED indicates whether CO2 is being dosed or not. Moreover, the T-Micro CO2 Controller has a built-in calibration function, so you can calibrate the CO2 sensor in fresh air.

This CO2 controller comes without a sensor.

Features:

- Plug & Play.

- Can be used in small to very large spaces.

- Built-in calibration function to calibrate the CO2 sensor in fresh air.

- Adjustable from 300 - 2000 ppm.

- Min/Max display for CO2.

- Indicator led indicates when CO2 is dosed.

- Switches the CO2 source (CO2 generator, CO2 cylinder) ON/OFF by means of a 230V relay.

- Memory for setpoint and hysteresis in case of power failure.

- Automatic 110V/230V detection.

- The external sensor has a light sensor that automatically switches between day and night settings.

- Automatic detection of cable failure or poor connection with the sensor(s).

- Sensor connection with standard network cable (UTP). Included is a cable of 5 meters.

- Controller and sensor are available separately.

- Various sensors are available separately.

- Possibility to connect the TechGrow Datalogger (DL-1).

The CO2 Controller regulates temperature, humidity and CO2 content in the room.

CO2 Sensor

The Dimlux CO2 Sensor detects levels of carbon dioxide present in the surrounding atmosphere and feeds the information back to the Dimlux Maxi Controller. The Sensor also powers the (separately available) CO2 Regulator. This system ensures that optimal levels are distributed at all times, minimising wastage and maximising plant growth. The CO2 Sensor will even shut down CO2 distribution automatically during lights-off, thanks to it's built-in light cell.

CO2 supplementation is an absolute must in closed loop environments, where little-to-no fresh air is drawn in from outside. Users of the Opticlimate have been running their climate control systems in conjunction with the Maxi Controller's CO2 distribution system to great effect. The results are, quite simply, staggering!

• This is a money saving combo deal comprising of the Dimlux Maxi Controller and the Dimlux CO2 Sensor:
• Maxi Controller
• The Dimlux Maxi Controller is probably the most comprehensive piece of growroom equipment we’ve ever come across. As well as regulating the switching of your Dimlux lighting systems (removing the need for a contactor / timer), the Maxi Controller also continuously regulates their output levels to ensure that plant temperatures and VPD (vapour pressure deficit) levels are always perfect. It does this using data gathered by external temperature and humidity probes, as well as the revolutionary infra-red Dimlux Plant Temperature Camera . If this wasn’t enough, the Maxi Controller will even take care of CO2 distribution, as well as switching heaters and humidifiers!
