Testo 0636 9775 Offers

Use the robust humidity/temperature probe with the compatible Testo 440 multifunction measuring instrument (sold separately) to measure relative humidity and air temperature. Absolute humidity, wet bulb temperature and dew point are calculated at the same time. Store individual readings directly in the measuring instrument by pressing the button on the probe. The clearly structured measurement menu for long-term measurement enables the measuring instrument to be operated intuitively. Reading trends are reliably recorded thanks to the convenient input of measurement time and measuring cycle. The robust humidity/temperature probe was specifically designed for use in sophisticated production and treatment processes. The screwable PTFE sintered filter is highly resistant to aggressive media and is water-repellent, and reliably protects the humidity and temperature sensor. The probe can be used in dusty atmospheres, at high air velocity and under mechanical stress: for example, for measurements in industrial exhaust air (during drying processes), in bulk materials and in climatic test cabinets.

• Intuitive: clearly structured measurement menu for long-term measurement and parallel determination of the relative humidity and air temperature in indoor areas
• Precise: calculation of wet bulb temperature, dew point and absolute humidity
• Convenient: Universal connection handle can be easily combined with other probe heads
• Intelligent calibration concept. Only the probe tip needs to be sent for calibration.
