TECO Replacement Temperature Probe for TK 2 and TK 4 Aquarium Chillers

The TECO temperature probe is the original sensor that tells the chiller’s thermostat how warm the water is, so the unit can switch cooling on and off at the right moment. It has a stainless steel sensing tip on a long black cable, as shown in the photo, and is made as a direct replacement for TECO TK 2 and TK 4 chillers. A faulty probe can cause wrong readings or erratic cooling, so replacing it restores accurate control.
