Use of CO2 as a refrigerant has been on the rise due to its low cost, heat transfer properties, energy efficiency and low environmental impact. CO2 can be difficult to detect due to its colorless, odorless properties and exposure to high concentrations poses a serious health risk. Installing transmitters as close to potential leak detection points as possible is key to ensuring the safety of facility personnel. Emerson offers an accurate and durable sensor for retailers.
