3M NTC Floor Temperature Sensor Probe – Underfloor Heating
3-Metre NTC Floor Temperature Sensor Probe for Underfloor Heating Thermostats
Keep your underfloor heating system running accurately and efficiently with this precision NTC temperature sensor probe. Featuring a 3-metre (9.84 ft) cable, this accessory connects effortlessly to most underfloor heating thermostats, giving you reliable floor temperature readings so your heating system always performs at its best.
Key Features
- 3-Metre Cable Length: Offers generous reach for flexible placement beneath flooring or along pipework.
- NTC Thermistor Sensor: 10KΩ resistance at 25°C (R25 = 10KΩ) with B25/50 = 3950K and B25/80 = 4021K — delivers consistent, accurate temperature readings.
- High Accuracy: ±0.5% accuracy ensures precise temperature monitoring for efficient heating control.
- Durable Rubber Housing: Thermoplastic rubber protective casing shields the NTC sensor from moisture and everyday wear.
- Versatile Use: Ideal for measuring floor temperature via thermostat, monitoring piping/water temperature, and tracking indoor or outdoor ambient temperature.
- Easy Installation: Simply connect to your existing underfloor heating thermostat; the probe can be adhered directly to electrothermal film.
- Brand New Condition: 100% new, never used.

Frequently Asked Questions
Q: Is this floor temperature sensor probe compatible with all underfloor heating thermostats?
A: This NTC sensor probe (10KΩ @ 25°C) is compatible with the vast majority of underfloor heating thermostats that accept a standard NTC 10K thermistor. We recommend checking your thermostat's specifications to confirm compatibility before purchasing.
Q: Can this sensor probe be used for purposes other than floor temperature sensing?
A: Yes! While it is primarily designed for underfloor heating thermostat systems, the 3-metre probe is also suitable for monitoring piping water temperature, indoor ambient temperature, and outdoor temperature — making it a versatile addition to any heating or monitoring setup.
Q: How is the sensor probe installed?
A: Installation is straightforward. Simply connect the cable to the designated sensor terminals on your underfloor heating thermostat. The probe itself can be placed beneath the floor, adhered to an electrothermal film, or positioned along pipework, depending on your monitoring needs. No special tools are required.
