Digital NTC 10K 3950 Waterproof Temperature Sensors Temp Silicone Probe 6 Feet(2m)

Works well, doesn't fluctuate much. Nice long cord. I use the thermostat controller to warm up my 700 gal above ground pool. Had to purchase a replacement sensor because I had it placed above the exhaust of the heater so once the flame went out, it would shut off the magnetic propane valve to the outdoor water heater by shutting off the actual water temp controller. Once it cooled down it would send power to the actual water temp thermostat controller again and if not at set temperature, would turn on the circulation pump, re-open the magnetic valve and re-ignite the heater. Well somehow it wasn't that secure and moved over just enough to melt the insulation. But yes, this sensor works with the old Wteske temperature controller if you are still using one. I have three wifi versions and they've never given me any problems.

This product works but the temperature is off by about 10 degrees. Adjusting the settings at the controller allows me to overcome this shortcoming.

Works well in my temperature controller

Purchased to monitor liquid temperature. Last thru the return window, now doesn’t work.
