Description
This wired high-precision humidity/temperature probe (0636 9772) is engineered for demanding environments. It accurately measures relative humidity and air temperature, with simultaneous calculation of wet bulb temperature, dew point, and absolute humidity when paired with a compatible Testo multifunction instrument.
Its robust design ensures reliable performance in critical processes within cleanrooms, laboratories, and the pharmaceutical, industrial, and food sectors. It's also ideal for monitoring conditions in storage, refrigerated, and work rooms, as well as air conditioning/ventilation ducts.
Precision in humidity and temperature measurement is crucial for maintaining environmental quality, product integrity, and operational efficiency. This probe provides trustworthy results, traceable to international standards like ILAC, PTB, and NIST, ensuring compliance and confidence in your data.
What's Included
- High-precision humidity/temperature probe head
- Cable handle (1.4 m length)
- Calibration protocol
Features & Benefits
- Intuitive measurement menu for long-term recording and parallel determination of RH and air temperature.
- High accuracy: ±(0.6% RH + 0.7% of m.v.) for 0 to 90% RH, traceable to international standards.
- Calculates wet bulb temperature, dew point, and absolute humidity automatically.
- Equipped with a long-term stable humidity sensor for proven Testo quality and reliable results.
- Button on probe allows direct storage of individual readings in the measuring instrument.
- Intelligent calibration concept: Only the probe head needs calibration, keeping the instrument in continuous use.
- Space-saving: Universal handle concept allows connection to other probe heads for versatile applications.
Applications
- Critical Processes: Guarantee process climate in cleanrooms, ensure quality in industrial processes, calibrate climatic test cabinets.
- Ventilation Ducts: High-precision humidity and air temperature measurements with its 12 mm diameter probe head.
- Storage & Refrigerated Rooms: Accurately monitor relative humidity and air temperature within a wide measuring range.
- Work Rooms: Monitor relative humidity, air temperature, dew point, and wet bulb temperature for occupant comfort.
- Refrigeration Systems & Heat Pumps: Measure RH and air temperature to determine heating and cooling output.
Tradie Pro Tip: Avoid using this probe in condensing atmospheres. For continuous applications in high-humidity ranges (e.g., > 80% RH at ≤ 30 °C for > 12 hours), it's best to consult Testo Service to ensure optimal performance and longevity.
