GMP252 CO₂ Probe

User 's Manual Selection table

The GMP252 CO₂ probe is an intelligent, independent ppm level probe. This probe can be used to measure CO₂ in agriculture, refrigeration, greenhouse and harsh HVAC applications as well as for plant growth chamber manufacturers.It is suitable for harsh and humid environments requiring stable and accurate measurement of ppm CO₂. Operating temperature range is -40 to +60°C, measuring range is 0 to 10,000 ppm CO₂, and can even be used to measure CO₂ up to 30,000 ppm, but with slightly reduced accuracy.The GMP252 can also be placed inside the Visala radiation-shield DTR250 for dynamic measurement of outdoor CO₂ levels.

Features:

• Ø Measuring range 0... 10000 ppm CO₂
• Ø Can be used to measure even up to 30 000 ppm of carbon dioxide, but with reduced accuracy
• Ø Intelligent stand-alone probe with analog (V, mA) and digital output (RS485 using the Vaxala protocol or Modbus)
• Ø Using Vaisala second generation CARBOCAP® technology, stable performance
• Ø Wide operating temperature range: -40... + 60 ° C
• Ø IP65 enclosure protection grade
• Ø Full temperature and pressure compensation
• Ø Integrated temperature measurement for CO₂ compensation
• Ø Compensation for background gas, O₂ and humidity
• Ø The sensor probe is heated to prevent condensation

Easy to use and clean: The GMP252 is an intelligent all-in-one probe that can be easily and quickly installed. The probe is resistant to dust and most chemicals, such as hydrogen peroxide and alcohol based cleaners. The probe surface is smooth and easy to clean.

Reliable and accurate: With a wide operating temperature range, the GMP252 is suitable for a large number of applications. The probe provides accurate and stable CO2 measurements under different conditions.
