The Vaisala CARBOCAP® carbon dioxide (CO2) sensor, released in 1997, employs innovative technology. It features a silicon-based variable filter using Fabry-Perot interference (FPI) in a single-source dual-wavelength comparison infrared non-dispersive method. Boasting high reliability and stability, this sensor has been providing accurate CO2 measurements across a wide range of fields and applications, from building automation and safety to life sciences and environmental research, for over 15 years.

The Vaisala CARBOCAP(R) GMP343 CO2 probe is a robust and highly accurate probe-type measuring instrument. It is primarily used for ecological measurement applications, including soil CO2 respiration, atmospheric CO2 monitoring, plant greenhouses, and OEM products. The GMP343 has no moving parts and incorporates a single light source dual-wavelength method for CO2 measurement.

The Vaisala CARBOCAP(R) GMP231 CO2 probe is designed for incubator manufacturers, providing accurate and reliable CO2 measurement and durability for high-temperature sterilization up to +180°C. The GMP231 CO2 probe utilizes Vaisala's patented CARBOCAP(R) technology and a new type of infrared (IR) light source.

The Vaisala CARBOCAP® GMP251 CO2 probe is an intelligent probe for high concentration CO2 measurement. The GMP251 is ideal for demanding applications that require stable and accurate CO2 concentration measurements, such as life science incubators, cold rooms, and the transport of fruits and vegetables, where excellent stability, reliability, and accuracy are essential. The operating temperature range is -40 to +60°C, and the measurement range is 0 to 20% CO2. The GMP251 CO2 probe belongs to the Indigo product series and can be connected to the Indigo 200 series transmitter for extended functionalities such as display and relay. It can also be used for spot checks when connected to the GM70 handheld CO2 meter. The GMP251 is the successor to the following discontinued models: GMM221, GMT221. Spare parts and accessories for the GMP221 CO2 probe are still available.

The Vaisala CARBOCAP(R) GM70 handheld CO2 meter measures the volumetric concentration of CO2 in ppm or percentage. It is an easy-to-use measuring instrument for spot checks in laboratories, greenhouses, mushroom farms, and for CO2 alarm applications in the bottling process of drinking water. Additionally, it can be used as a checking tool for fixed CO2 meters in general HVAC systems and various industrial applications. The optional GM70 pump is used for suction sampling in hard-to-reach places such as incubators and chambers.

The wall-mounted Vaisala GMW90 CO2 humidity and temperature transmitter is ideal for green building projects. This product measures CO2 and temperature, and humidity measurement is also available as an option. A traceable calibration certificate is included with this instrument. The traceability of the sensor can be easily maintained through an intelligent measurement module that can be replaced on-site. This product can be harmonized with the building's interior design using an optional decorative cover.

When monitoring both indoor air quality (IAQ) and occupancy density, measuring CO2 with a single sensor is the most economical method. If ventilation is inadequate, CO2 levels will rise, leading to drowsiness and decreased productivity. Indoor air quality can be improved based on occupancy density levels. Minimizing uncontrolled ventilation contributes to energy savings. To perform high-precision and stable measurements in general HVAC systems, the wall-mounted Vaisala GMW80 series CO2 humidity and temperature transmitters offer top-class stability and reliability among commercially available products, providing this performance over a product lifespan of 15 years. This product is designed for standard demand-controlled ventilation systems. The GMW80 series is ideal for facilities that operate 24/7.

In the first half, we will explain the importance of selecting CO₂ measuring instruments used in agriculture from the perspective of TCO, the characteristics of various CO₂ measuring technologies, and the technical background that demonstrates the excellent long-term stability of Vaisala's CO₂ meters. In the second half, we will introduce applications of CO₂ meters utilized in agriculture. Additionally, we will specifically discuss the following topics: - Potential risks that may arise when measuring CO₂ - Useful advice for ensuring reliable CO₂ measurement practices, among others.

With Vaisala Insight software, you can quickly access the settings and data of the Indigo product series measurement probes and other compatible Vaisala devices. The probes can be removed from the process and connected to a PC via USB cable for configuration and field calibration, allowing for simultaneous connection of up to 6 devices. It is available in English and Japanese versions and is compatible with 64-bit versions of Windows 7, Windows 8.1, and Windows 10.

The Vaisala CARBOCAP GMP252 CO2 probe is an intelligent probe for measuring CO2 at ppm levels. The GMP252 measures CO2 in applications such as agriculture, CO2 refrigerants, greenhouses, and demand-controlled HVAC systems. It is suitable for stable and accurate ppm level measurements of CO2 in harsh, high-humidity environments. The operating temperature range is -40 to +60°C, and the measurement range is 0 to 10,000 ppm CO2, with the capability to measure up to 30,000 ppm CO2 depending on accuracy. The GMP252 can also be installed within the Vaisala DTR250 radiation shield for dynamic outdoor CO2 measurements. The GMP252 CO2 probe belongs to the Indigo product series and can be connected to the Indigo500 series transmitter or Indigo200 series transmitter for expanded functionality such as display and relays. It can also be used with the free Vaisala Insight software. It can be connected to the GM70 handheld CO2 meter for use as a spot check.
