RS PRO Type K Bow Surface Temperature Probe, Surface, 110 mm Length, 6 mm Diameter, 180°C Max, 255-550

The RS PRO 255-550 Type K Bow Surface Temperature Probe is a precision thermocouple probe designed for accurate surface temperature measurement in a variety of industrial, laboratory, and technical settings. Featuring a probe length of 110 mm and diameter of 6 mm, this surface probe is engineered to ensure optimal contact with curved and uneven surfaces, such as machine rollers and pipes commonly found in paper mills and manufacturing plants.

With a robust bow tip configuration, the probe delivers reliable surface readings and rapid thermal response, supported by a 10 second response time. The integrated 2 meter cable provides flexible reach, making it simple to connect with equipment and data loggers, while the mini plug connector is compatible with a wide range of standard industrial and laboratory thermometers and meters. The probe is compatible with temperature logging systems, calibration setups, and industrial test and measurement instrumentation.

The thermocouple sensor is enclosed in a PTFE ribbon to minimize frictional heat generation, which adds to the probe’s accuracy and enhances safety during surface measurement. It delivers a high precision with an accuracy of ±0.25 percent, supporting reliable measurement of both low and high temperature ranges, with a maximum surface temperature capability of 180°C and a minimum measurement of -50°C.

Applications include temperature monitoring and calibration in industrial machinery, laboratory testing, electronic equipment servicing, calibration labs, home appliances, and patient monitoring systems. The compact, bow-shaped design is especially valuable where measurement access is difficult or where standard immersion probes cannot be used.

Typical users include plant maintenance technicians, laboratory specialists, HVAC professionals, and process engineers needing accurate surface temperature logging for quality control, process validation, and troubleshooting.

Type K thermocouple probe allows accurate surface temperature measurement up to 180°C. 110 mm probe length and 6 mm diameter support efficient contact with both curved and uneven surfaces. Durable bow probe tip design ensures reliable readings on rollers and other machinery parts.
