What It Is
This is a waterproof digital thermal probe, specifically an NTC thermistor probe, with a resistance of 10K (B3950). It is designed to measure temperature and is supplied as a single piece. Thermistors work by changing their electrical resistance in response to temperature variations. As the temperature changes, the resistance of the thermistor also changes, which can then be measured to determine the temperature. This particular model features water resistance, making it suitable for damp or submerged environments.
Key Uses & Applications
This 10K NTC thermistor probe is ideal for temperature sensing in environments where moisture is present, thanks to its water resistance. Digital thermal probes like this are commonly used in heating, ventilation, and air conditioning (HVAC) systems, as well as in refrigeration units, industrial process control, and environmental monitoring. Its ability to provide digital temperature readings makes it suitable for integration into various electronic circuits and control systems for accurate measurement and regulation.
How to Choose
When selecting a thermistor probe, consider the specific length required for your application; this product is available in lengths of 0.5 m, 1 m, 2 m, 3 m, 5 m, and 10 m. Ensure the 10K resistance (B3950) matches your system’s requirements. A thermistor works by altering its resistance with temperature, so compatibility with your measurement equipment is crucial. The waterproof feature is important if the probe will be exposed to liquids or high humidity.
Grit / Spec Guide
This product is a 10K (B3950) NTC thermistor probe, meaning it has a nominal resistance of 10,000 ohms at 25 degrees Celsius, with a B value of 3950. The B value indicates the relationship between resistance and temperature. It is a digital thermal sensor. The available cable lengths are 0.5 m, 1 m, 2 m, 3 m, 5 m, and 10 m. Its water resistance makes it suitable for submerged or damp applications. Always verify the resistance and B value against your circuit specifications.
Care & Safety
When handling the thermistor probe, avoid bending the cable sharply, especially near the sensor head, to prevent damage to the internal wiring or the waterproof seal. While the product is water resistant, ensure that the connection points to your control system are properly insulated and protected from moisture if they are not also rated for water resistance. Thermistors work by sensing temperature, so protect the sensor tip from physical impact. Store in a dry place when not in use.

Sensor Type: NTC Thermistor. Q: What's the operating temperature range for these probes? A: These are B3950 10K NTC thermistors. They are generally accurate for measuring temperatures in common applications like liquid tanks or environmental monitoring, typically from about -40°C to 125°C.. Q: How waterproof is the sensor probe? Can it be permanently submerged? A: The probe end, which is encased in stainless steel, is fully waterproof and can be left submerged in water or other liquids. The cable is water-resistant, but the wire ends that you connect to your circuit should be kept dry.. Q: Is this thermistor easy to connect to a microcontroller like an Arduino? A: Yes, it's pretty simple to use with platforms like Arduino. You'll typically set up a voltage divider circuit with another 10K resistor and use an analog input pin to read the value, which you can then convert to a temperature.. Q: What should I do if the sensor I receive is dead on arrival? A: We test our components, but faults can occur. If your sensor doesn't work or gives clearly incorrect readings right out of the package, please contact us immediately for a no-hassle replacement.. Q: Why are there so many different cable lengths to choose from? A: We offer a wide range of lengths, from 0.5m all the way to 10m, so you can get the right size for your specific project. This helps you avoid messy excess cable or the need to splice wires, resulting in a cleaner and more reliable installation..
