Testo Hot Wire Probe (Digital, Wired) – Including Temperature and Humidity Sensor
Testo Hot Wire Probe (Digital, Wired) – Including Temperature and Humidity Sensor
The Testo Digital Hot Wire Probe is a professional wired sensor module engineered for comprehensive air diagnostics across commercial ventilation ducts and industrial air handling systems. Operating with a built-in multi-parameter framework, this high-precision intelligent tool captures velocity up to thirty metres per second alongside parallel temperature, relative humidity, and absolute pressure measurements. It features automated atmospheric density compensation, a convenient handle control button, an extendable integrated one-metre scaling telescope, and a rugged rotatable protective tip shell to safeguard the delicate inner diagnostic sensors from airflow debris.

KEY FEATURES
- Digital multi-parameter probe for air velocity, volume flow, temperature, and humidity
- Automatic pressure compensation ensures accurate velocity and flow readings
- Measurement range up to 30 m/s – suitable for high and low velocity ducts
- Integrated sensors for temperature and humidity with high long-term stability
- Ergonomic handle with button for direct measurement control
- Telescope extends to 1.0 m (optionally extendable to 2.0 m) for deep ducts
- Rotatable protective cap safeguards the air velocity sensor
- Digital calibration for zero-error results – only probe head needs calibration
- Compatible with Testo 400, 440, and 480 multifunction measuring instruments
The Testo 0635 1572 Digital Hot Wire Probe delivers maximum process data resolution within demanding HVAC, engineering, and laboratory airflow environments. Built around an intelligent calibration design, this rugged wired probe processes environmental measurements internally to eliminate data transfer uncertainty and display error-free results. The integrated sensor array eliminates the need for managing separate probes by feeding air velocity, thermal conditions, and moisture matrices back to your master instrument simultaneously. By enabling targeted calibration adjustments solely on the detached probe head, your multi-function handheld meter can remain continuously deployed in active field rotations.
ADDITIONAL FEATURES
- Convenient handle button stores reading logs or triggers timed and multi-point averaging directly
- Rotatable protective mechanical shield prevents dust contamination during transport and downtime
- Clear, high-contrast metric scale printing on the extension telescope ensures precise insertion depth control
- Wide psychrometric sensing windows track high-accuracy relative humidity thresholds down to 5% RH safely
- Long 1.4-metre connection cable provides excellent physical freedom during deep duct testing procedures
- Heavy-duty housing blend finished in signature Testo black and orange for quick jobsite visibility
APPLICATIONS
- Perfectly optimized for air velocity, volume flow, temperature, absolute pressure, and relative humidity checking inside ventilation ducts, air outlets, laboratory safety cabinets, and commercial HVAC networks.
