Waterproof Thermistor Probe Wire 10K

The Waterproof Thermistor Probe Wire 10K is a precision NTC temperature sensor designed to deliver accurate and reliable temperature readings in both indoor and outdoor environments. Fully compatible with the popular W1209 digital temperature controller, this probe ensures stable performance in applications requiring water resistance, high durability, and long-term operational reliability.

Its stainless-steel sensing tip and sealed waterproof construction make it ideal for monitoring temperature in liquids such as water tanks, aquariums, hydroponics systems, incubators, and refrigeration units. The built-in NTC 10K thermistor offers high sensitivity with fast response time, providing precise readings from –50°C to +110°C, perfectly matching the working range of W1209 and similar thermostat modules like W3001, W2809, W1209WK, and others.

The probe comes with a high-quality insulated cable that resists moisture, corrosion, bending, and heat exposure. It connects directly to W1209’s 3-pin sensor interface without any modifications, making it extremely user-friendly for Arduino, Raspberry Pi, and NodeMCU IoT projects when building custom thermostatic control systems.
