1. Why CO2 is to be applied in a greenhouse? There are two reasons:
First, greenhouse CO2 in the greenhouse cultivation shed, there is information that: greenhouse day CO2 concentration changes before sunrise is about 500 ~ 600PPM; after sunrise, plant photosynthesis to absorb a large number of CO2 greenhouse CO2 concentration can drop below 100PPM.
The second is that in winter, the greenhouse film is put down and plays a role in insulation, so that a closed facility is formed, the CO2 concentration will decrease, and at the same time, the conditions for adding CO2 will be created. The added CO2 gas fertilizer is not easy to run off, and the CO2 Concentration is easy to control.
II. The main role of CO2 gas fertilizer application According to the increasing application of CO2 gas fertilizer in crops such as strawberry, watermelon, eggplant, cucumber, tomato, ground pu and pumpkin, there are five main functions: First, to increase the photosynthetic efficiency of plants. The second is to increase the internal and external quality of agricultural products and increase the benefits; the third is to increase the yield, especially the early yield of fruits and melons; the fourth is to raise the morning market time; and the fifth is to enhance the resistance of the plants and improve the products. Storage resistance. In the non-in vitro proliferation of plants, the photosynthetic efficiency of leaves is particularly important. Increasing CO2 concentration can significantly increase photosynthesis, synthesize more organic matter, and transport it to the incision to promote the activation of incision cells and the formation of roots.
Therefore, the application of carbon dioxide detectors in vegetable greenhouses is very extensive.
The characteristics of agricultural CO2 detectors are designed specifically for agricultural facilities, such as greenhouses, food and vegetable storage rooms, and real-time monitoring of CO2 concentration, temperature and humidity values ​​through preset programs.
Wall mounting, LCD display.
CO2 sensor, external temperature and humidity sensor, sensor probe can be separated from the body.
Infrared (NDIR) CO2 sensor, 15 year service life, CO2 range can be selected: 0～2000ppm/0～20000ppm/0～50000ppm
Unique ABCLogic self-calibration feature ensures CO2 sensor lifetime up to 15 years Temperature Setting range: 5 ~ 45 °C Humidity Setting range: 5 ~ 95% RH Provides three dry contact output control CO2 equipment, heating equipment, humidification or dehumidification equipment .
Unique photo-sensing device automatically controls CO2 generation in day-night mode. The device allows end-users to limit day-night CO2 concentration through photoreceptor elements.
RS-485 communication interface connects PC (optional), 15KV anti-static protection.
A variety of models, high precision, low price, high cost performance.
