Carbon Dioxide (CO2) Sensors

These CO₂ measurement sensors are highly versatile and precise, designed for %-level and ppm-level measurements in diverse applications, including life science incubators, agriculture, refrigeration, and environmental monitoring. With advanced technology and robust construction, they ensure exceptional stability, reliability, and ease of use, even in harsh and humid environments. Sensors feature analog (V, mA) and digital outputs (RS485, Modbus, Vaisala Industrial Protocol) for seamless integration and compatibility with Vaisala Indigo transmitters (Indigo500, Indigo300, and Indigo200 series) for extended functionalities.

Application Features:

• %-level: 0 … 20% CO₂, ideal for life science incubators, cold storage facilities, and demanding industrial processes.
• ppm-level: 0 … 10,000 ppm CO₂ (expandable up to 30,000 ppm with reduced accuracy), suitable for agriculture, greenhouses, HVAC systems, and plant growth chambers.
• Built with second-generation CARBOCAP® technology for superior long-term stability and precise CO₂ measurement.
• Functions in temperatures from -40 … +60 °C with integrated compensation for temperature, pressure, background gases, oxygen, and humidity.
• Heated sensor heads prevent condensation for reliable performance in challenging environments.
• IP65-rated housing resists dust and most cleaning agents (e.g., H₂O₂ and alcohol-based solutions). The smooth surface design ensures ease of maintenance.
• Compatible with Insight PC software for enhanced usability and the Indigo80 handheld indicator for spot-checking.
