Testo CO₂ Probe (Digital, Wired including Temperature and Humidity Sensor)

The Testo 0632 1552 Digital CO₂ Probe delivers accurate and reliable indoor air quality (IAQ) measurements in environments such as offices, laboratories, production floors, and storage areas. Designed for use with compatible Testo multifunction measuring instruments (e.g. Testo 400, 440, or 480), it measures CO₂ concentration, humidity, and air temperature with precision, and automatically calculates dew point, wet bulb temperature, and absolute humidity.

This wired version ensures stable and interference-free data transfer, ideal for fixed monitoring points or environments where wireless connections are restricted. With an integrated absolute pressure sensor, it automatically compensates for air density to ensure high-accuracy CO₂ measurements.

The intuitive long-term measurement menu enables easy data logging, allowing users to monitor environmental trends and evaluate changes in air quality over time. Individual readings can also be stored directly on the measuring instrument via the convenient handle button.

Built on Testo’s intelligent calibration concept, the probe head can be recalibrated independently—ensuring maximum uptime and zero measurement drift without taking the instrument out of service.

Testo Wired CO₂ Probe - Key Features

  • Accurately measures CO₂ concentration, temperature, and humidity
  • Calculates dew point, wet bulb, and absolute humidity automatically
  • Wired connection for robust and reliable data transmission
  • Integrated absolute pressure compensation for precision results
  • Compatible with Testo multifunction instruments (Testo 400 / 440 / 480)
  • Intelligent calibration concept – recalibrate probe head only
  • Ergonomic handle with button for easy data logging
  • Stable long-term Testo humidity sensor traceable to ILAC, PTB, and NIST
  • Ideal for IAQ assessments, workplace studies, and environmental testing
