Questions about this product
- What does the '10K 1% 3950' mean on these thermistors?
- The '10K' is the resistance in Ohms at 25°C, '1%' is its accuracy tolerance, and '3950' is the B-value constant. You'll need these figures to correctly configure your controller or software to get an accurate temperature reading.
- Are these probes actually waterproof for continuous use in a water tank?
- Yes, the stainless steel probe end is fully sealed and can be submerged in water. The PVC-coated wire itself is not designed for permanent underwater installation, so it's best to keep the cable connections dry.
- I need to replace a sensor on my W1209 controller. How do I pick the right one?
- The W1209 and W1401 controllers typically use a 10K NTC thermistor, so that's likely the one you need. We always recommend checking your controller's manual to be certain, but the 10K 1% 3950 option is the standard replacement for most of those units.
