Description
Product Overview
The Testo 0635 1572 Hot Wire Probe is a digital, wired instrument designed for precise environmental measurements in ventilation systems. It accurately determines air velocity, volume flow, air temperature, and humidity, making it an indispensable tool for HVAC technicians.
Engineered for ease of use, this probe connects to a compatible Testo multifunction measuring instrument (sold separately) to provide reliable data crucial for system balancing and performance assessment.
Key Features & Applications
Why This Probe Matters
This hot wire probe ensures intuitive operation through a clearly structured measurement menu for volume flow, allowing parallel determination of key air parameters. It delivers precise results within a measuring range of 0 to +30 m/s and features automatic absolute pressure compensation for enhanced accuracy. Convenience is further boosted by a button on the handle for storing individual readings and a scaled telescope extendable up to 1m, with an option to extend to 2.0m.
What's Included
- Hot wire probe head including temperature and humidity sensor
- Handle adapter and cable handle (cable length 1.4 m)
- Telescope (extendable to 1.0 m)
- Calibration protocol
Features & Benefits
- ✓ Intuitive Measurement: Clearly structured volume flow menu for parallel determination of air velocity, volume flow, air temperature, and humidity.
- ✓ High Precision: Accurate measurement results from 0 to +30 m/s with automatic absolute pressure compensation.
- ✓ User-Friendly Design: Practical button on the handle for storing readings and convenient measurement with an extendable telescope.
- ✓ Intelligent Calibration: Only the probe head requires calibration, keeping your measuring instrument in continuous use.
- ✓ Integrated Sensor Protection: A rotatable protective cap shields the air velocity sensor from mechanical stress when not in use.
- ✓ Universal Handle System: Compatible with various probe heads, reducing equipment and saving space.
Applications
- Reliable measurement of flow velocity, air temperature, and humidity in ventilation ducts.
- Effective for large ventilation systems, especially when fitted with the optional 2.0 m telescope extension.
Tradie Pro Tip: For precise measurements in hard-to-reach ducts, the extendable telescope (up to 1m, 2m with extension) combined with the universal handle design streamlines your toolkit and ensures consistent readings.
