Carbon Dioxide is critical to plant growth and development. Photosynthesis requires Carbon Dioxide (CO2) concentrations in ambient air ranges from 300-500 parts per million (ppm). If you are growing Fruit or Vegetables in a greenhouse or indoors, the CO2 levels will reduce as the plants use up CO2 during photosynthesis. Increasing the CO2 levels in this environment is essential for good results. Additionally, there are benefits to raising the CO2 level higher than the global average, up to 1500 ppm. With CO2 maintained at this level, yields can be increased by as much as 30%.
It is important to both monitor the CO2 levels to make sure the plants get the optimum amount as well as ensuring that levels do not exceed the COSHH EH40 work place exposure Limits for worker safety.
Weatherall can offer fixed systems for CO2 from 1 to 96 channels for monitoring CO2 in the boiler rooms and GX-3R Pro personal gas monitors for CO2 for EH40 compliance for worker protection.
Fixed and Portable CO2 Solutions
Plant rooms are often situated underground. This is by design to save space or by virtue of being built into existing basements or chambers. Underground Plant Rooms often contain an array of machinery such as Pumps, Boilers, Sprinkler Systems or Generators.

View StoryCatalytic combustion sensors are the standard method for detecting combustible gases including Hydrogen, however in order to operate a minimum of about 10% Oxygen needs to be present. IR sensors are a good solution to this problem for measuring most combustible gases in an inert environment where O2 levels are below 10% volume but IR sensors cannot detect Hydrogen.
Riken Keiki offers several solutions around this problem.
