Tape Sensor testo 0613 4611 NTC temperature probe, tape format, measurement range -50 to 70°C

The testo Tape Sensor 0613 4611 is an NTC temperature probe in a flexible tape format designed for surface and contact temperature measurements. With a measurement range from -50 to 70°C, this tape-style sensor is suitable for monitoring pipes, ducts, flat surfaces and other areas where a slim, conformable probe is required. The tape format enables secure placement by wrapping or adhering the sensor to the measurement point for stable, repeatable readings when paired with compatible meters and data loggers.

Advantages

The flexible tape design offers good contact with irregular or curved surfaces and maintains consistent thermal coupling for accurate readings. The NTC sensing element provides fast response time across the specified temperature range. Its thin profile and adhesive-friendly surface make it easy to attach to pipes, ducts and flat panels without adding bulk. The robust construction supports routine HVAC, refrigeration and laboratory checks where reliable surface temperature data are needed.

How to use

Attach the tape sensor directly to the measurement surface, ensuring full contact along the sensing area. For pipes or curved surfaces, wrap the tape around the circumference and secure it so the sensor remains in stable contact. For flat panels, press the tape firmly onto the surface; use suitable adhesive or tape to maintain placement if prolonged monitoring is required. Connect the sensor to a compatible testo meter or data logger according to the instrument's input specifications and allow the reading to stabilize before recording measurements.

Recommendations

Use the tape sensor on clean, dry surfaces to ensure good thermal contact. Avoid placing the sensor where direct radiant heat or airflow could cause misleading surface readings. For long-term monitoring, verify adhesive compatibility with the surface material and periodically check the sensor placement to maintain accurate measurements.
