testo 905-T2 – Surface probe

testo 905-t2 surface thermometer

Order-Nr.  0560 9056

The Testo 905-T2 is a professional-grade surface thermometer (also called a surface probe) designed for reliable temperature measurement on both smooth and uneven surfaces. With its sprung thermocouple head, it adapts perfectly even when measuring on pipes, valves or irregular surfaces.

Whether you’re in HVAC service, refrigeration, industrial maintenance or pipework quality control, this digital surface thermometer meets high demands for accuracy, speed and durability.

Key Features of the Testo 905-T2 Surface Probe

The Testo 905-T2 surface probe offers fast, reliable, and precise surface temperature measurement, making it ideal for HVAC, industrial, and maintenance applications.

• Dual-range Type K thermocouple sensor for surface temperature measurement.

• Measuring range: −50 °C to +350 °C (short-term up to +500 °C) — excellent for demanding surface tasks.

• Accuracy: ±(1 °C + 1 % of reading) typical in range (−50 to +350 °C).

• Resolution: 0.1 °C for precise measurement results.

• Sprung thermocouple “cross-band” probe provides fast measurement on uneven surfaces.

• Rotatable display for easy readability from different angles—ideal for field work and difficult-to-access surfaces.

• Designed for quick response time (~5 seconds to t₉₉) and intuitive use.

testo 905 t2 Application

Use the Testo 905-T2 surface probe for:

• Measuring surface temperature on hot/cold pipes, flanges and valves.

• HVAC system checks and maintenance where surface sensors are needed.

• Refrigeration and plumbing installations with uneven or curved surfaces.

• Industrial service and diagnostics where reliable surface thermometry is critical.

Because it’s built for both smooth and rough surfaces, it outperforms many other sensors when you need measurement on challenging geometries.
