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.
