This device uses the oscillation of high frequency ultrasound to transform the electrical oscillation into mechanical oscillation, using a ceramic disc of 12 membranes, and you can add up to 3 discs more of 12 membranes to get more power.

So Ocean Mist turns water into steam, eliminates static electricity and freshens the air.It is suitable for humidifying large crops or greenhouses.Keep in mind that in dry areas or excess heat greenhouses, there is a low relative humidity. Also you must know that growing plants should be between 60 and 75% relative humidity, at flowering under 60% and cuttings over 80% relative humidity.

Powerful humidifier able to generate 7 liters of fog per hour thanks to a powerful system of ceramic ultrasonic plates with nickel and titanium alloy.

It has an external potentiometer that controls a fan integrated into the humidifier's own structure. This fan drives the moisture so that it reaches all points of the greenhouse and distributes evenly. It has a network outlet for direct connection to a tap or water supply. There is an NH50 filter so that the water becomes as clean as possible inside the humidifier, although it would be appropriate to use osmosis water to increase the life of ceramic discs.

They should be replaced when you notice that the generated humidity level is different than usual.

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.

• Datalogging Indoor Air Quality Monitor- 800049
• Records up to 32,000 data points that can be downloaded to your computer using the USB cable included. 
• Dimensions: 4½" × 4¼" × 1" (108 × 115 × 25 mm)

 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.

Technical specs:

• Super large LCD simultaneously display of CO2 level, Temp., relative humidity, Date and Time.
• Six (6) smiley icons indicate indoor air quality levels (350/450/700/1000/2500/5000ppm), easy to understand CO2 concentration.
• Stable NDIR sensor for CO2 detection
• Hi alarm threshold is selectable, easy to reset default setting by pressing one button. Automatic Baseline Calibration (ABC)
• Audible warning for high CO2 concentration
• Visable LED meter status.

The Can-Lite carbon filter is the latest addition to the Can-Filters Carbon filter range.

Recently released after years of testing and research, the Can-Lite has been developed with ease of installation, durability and effectiveness in mind. The Can-lite is manufactured using a similar process to Can-Filter 'Classic  but instead using a highly perforated, light aluminum casing and a special grade of virgin CKV-4 carbon. This allows the filters to be lighter and handle larger air flow rates without any odor breakthrough.

How the Dimlux Maxi Controller & CO2 Sensor Work:

• 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!
• 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!
