For measurement in harsh environments.
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.
High concentration measurement for applications with strict requirements such as life science incubators and cold rooms.
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.
For ppm level measurement in applications such as agriculture, CO₂ refrigerants, greenhouses, and demand-controlled air conditioning.
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.
For CO₂ incubator
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.
