Description
This dual-probe sensor assembly features matching 1/4″ diameter probes on both the temperature and high limit sensors. Commonly installed in spa configurations utilizing firestick or heat jacket systems rather than conventional heating elements. The compact 1/4″ temperature probe diameter allows insertion into thermowell fittings positioned within the plumbing lines instead of mounting through the spa shell wall. Frequently specified in Dreammaker and similar spa brands.
Always verify both probe diameters match your existing setup before purchasing, as most sensor assemblies feature larger temperature probe dimensions.
