Testo CO₂ Probe (Digital, with Bluetooth® including Temperature and Humidity Sensor)
The Testo 0632 1551 CO₂ Probe with Bluetooth® is a high-precision digital sensor designed for indoor air quality (IAQ) monitoring in offices, schools, production areas, and storage facilities. It simultaneously measures CO₂ concentration, humidity, and air temperature, while automatically calculating dew point, wet bulb temperature, and absolute humidity.
Featuring Bluetooth® wireless connectivity (up to 20 m range), the probe delivers real-time data directly to compatible Testo multifunction instruments such as the Testo 400, 440, or 480. Its integrated absolute pressure sensor ensures precise CO₂ measurements through automatic air density compensation.
The intuitive long-term measurement menu allows detailed trend tracking, enabling you to analyze air quality changes over time. With a simple press of the handle button, you can save individual readings or start/stop measurement series directly from the probe.
Thanks to Testo’s intelligent digital calibration system, the probe head can be recalibrated independently—keeping your measuring instrument continuously in operation. Built for comfort and efficiency, it’s the perfect choice for reliable and wireless indoor air quality diagnostics.
