XINGYHENG 10Pcs NTC 10K Thermistor Sensors Digital Temperature Probe for Air Conditioner (100cm)

work well real affordable but a couple quit being accurate after a couple days in saltwater seems like the water gets in around the wires so i encased em in a plastic straw and siliconed the ends and that seems to do the trick

I used a silicone sealant and heat shrink and it worked for quite a while. The first unprotected one died within a couple of days.

Work as described

I bought these to replace a faulty sensor on an Intex Purespa which was giving an E96 error. Only needed 1 but by buying 10 I got Prime next-day delivery.I ordered the correct parts to replace both sensors from Thermomart (as advised by the Internet) but they never arrived after over a month - so I missed Christmas and New Year with the tub. Lost patience and ordered these. Needed to cut off and drill-out the old sensor from the nut that holds the sensor in place - then insert one of these new ones into the nut and seal it in place with silicone sealant.Works a treat! I may replace it when the Thermomart parts arrive - but in the meantime the hot tub is back up and running and I have 9 spare!

Would use this product again, installed 10 in my golf club boiler house to record heating pipe work temperatures.
