Jaycar bait and switch

Ripped offApril 2026

Comes with spec sheet. When you punch all the resistance to temp values in, it's off by a mile. Turns out these are generic 3950 thermisters, who would have thought? Don't waste your time and money, just order from Ali.

Works perfectly and accurately

I needed to replace a bad thermistor on a cheap thermostat that had drifted to give an error of 2°C and this brought the readings back into line. Very fast to react to temp changes too.
