Testo High-Precision Humidity/Temperature Probe (Digital, Wired)
The Testo 0636 9772 High-Precision Digital Humidity/Temperature Probe (Wired) delivers exceptional accuracy and stability for precise humidity and air temperature measurement in cleanrooms, laboratories, pharmaceutical environments, and HVAC systems.
Built with Testo’s renowned long-term stable humidity sensor, the probe provides outstanding accuracy of ±(0.6% RH + 0.7% of mv) across the range of 0 to 90% RH, with full traceability to international humidity standards such as ILAC, PTB, and NIST. It also automatically calculates dew point, wet bulb temperature, and absolute humidity, making it ideal for comprehensive climate monitoring.
The wired connection ensures uninterrupted data transmission and reliable readings in environments where Bluetooth use is restricted. The intuitive measurement menus on the compatible Testo measuring instrument (e.g. Testo 400, 440, or 480) allow easy long-term monitoring and analysis, with options for setting measurement intervals and trend visualization.
A button on the handle allows direct interaction with the instrument—store readings, start or stop measurement series, and monitor changing conditions seamlessly.
Thanks to the intelligent calibration concept, you only need to send the probe head for calibration, not the entire measuring instrument—eliminating downtime and ensuring a zero-error display. The universal handle system supports interchangeable probe heads, providing flexibility for various Testo applications.
