The Testo 0632 1550 CO₂ Probe Head is a professional-grade air quality sensor designed for precise and reliable measurement of CO₂ concentration, humidity, and air temperature. Compatible with Testo’s universal Bluetooth® or cable handles (available separately), this digital probe head is the perfect tool for monitoring indoor air quality (IAQ) in workplaces, laboratories, classrooms, and production environments.
Equipped with absolute pressure compensation and advanced digital sensors, the CO₂ probe head delivers highly accurate results even under varying environmental conditions. The integrated humidity and temperature sensors automatically calculate wet bulb temperature, dew point, and absolute humidity, providing comprehensive data for evaluating air quality and comfort levels.
With Testo’s intelligent calibration system, only the probe head needs recalibration, keeping your measurement system operational and cost-effective. The compact design and durable build make it ideal for both portable use and long-term monitoring setups.
