If the measured ohms do not match the standard A99B resistance chart at a known temperature

For high-pressure boiler applications and sophisticated multi-level liquid control

Flux-Cored Convenience: The integrated non-corrosive flux core means no messy paste and no secondary cleaning in most HVAC/R repair scenarios

Always verify your fan blade pitch matches this rotation to ensure proper airflow direction

System Reliability: Reduces moisture-related corrosion and mechanical sticking in pneumatic actuators and thermostats
