Overview

The Testo 0635 1571 Hot Wire Probe with Bluetooth offers a comprehensive solution for HVAC professionals. This digital probe accurately measures air velocity, volume flow, air temperature, and humidity, making it ideal for diagnostics in ventilation ducts.

Designed for convenience, it transmits readings wirelessly via Bluetooth to your compatible measuring instrument. Its intuitive operation and robust design ensure reliable performance in various HVAC applications, improving efficiency and accuracy on every job.

Why It Matters

Accurate air flow and environmental data are crucial for optimizing HVAC system performance and ensuring indoor air quality. This hot wire probe provides precise measurements, enabling technicians to quickly identify issues, verify system parameters, and maintain comfortable, efficient environments with minimal effort.

What's Included

• Hot wire probe head with temperature and humidity sensor
• Handle adapter
• Bluetooth handle
• 4 x AA batteries
• Telescope (extendable to 1.0 m)
• Calibration protocol

Features & Benefits

• Wireless Convenience: Bluetooth connectivity transmits readings up to 20m to your measuring instrument.
• Multi-Parameter Measurement: Simultaneously determines air velocity, volume flow, air temperature, and humidity.
• Extendable Telescope: Integrated telescope extends to 1.0 m with high-contrast scaling for easy depth reading; optionally extendable to 2.0 m.
• Intuitive Operation: Clearly structured measurement menu for volume flow with precise calculation and display of min/max values.
• Integrated Sensor Protection: Rotatable protective cap shields the air velocity sensor from mechanical stress.
• Intelligent Calibration: Only the probe head needs calibration, allowing the measuring instrument to remain in continuous use.
• High Accuracy: Precise measurement results from 0 to +30 m/s with automatic absolute pressure compensation.

Applications

• Accurate measurement of air velocity, temperature, and humidity in ventilation ducts.
• Volume flow determination in HVAC systems.
• Commissioning and maintenance of large ventilation systems (with optional extension).

Tradie Pro Tip: Leverage the intelligent calibration concept. By only needing to send the probe head for calibration, your main measuring instrument stays operational, minimizing downtime and keeping you on the job.
