Testo 0613 4611 Pipe Wrap Probe with Velcro, Max. 3 in. Diameter, NTC

The Testo 0613 4611 Pipe Wrap Probe with Velcro and an NTC sensor is used to carry out surface temperature measurements on pipes with a pipe diameter of up to 3 inches / 75 mm. For example, you can use it to determine the surface temperature of heating pipes.

The NTC sensor for measuring temperature is attached to a wide, 12 in. (300 mm) long strip. The Velcro fastener on this strip enables the surface probe to be attached to the pipe quickly and easily.

For optimum heat transfer between the surface probe and the measurement object, we recommend using our optional silicone thermal conduction paste (sold separately).

The surface probe features a cable, allowing you to also use it at measuring points which are not in close proximity to your data logger.
