Finlandia / Harvia Part # FH89 or ZSK-752 Bulb Cover for temperature sensor for KV heaters. is designed to shield your KV series sauna heater’s temperature sensor so it can measure accurately year after year.

Crafted from durable, sauna-ready material, it stands up to repeated heating cycles without warping or degrading. Using the correct OEM bulb cover is an important part of maintaining safety and reliability, making this replacement ideal for repairs, scheduled maintenance, or refreshing older installations.

  • Protective Sensor Cover – Shields the KV heater’s temperature sensor from steam, heat, and accidental impact, preserving accurate readings and extending sensor lifespan for consistent sauna performance.
  • Precise Compatibility – Designed specifically for Finlandia and Harvia KV series heaters, ensuring a perfect fit and reliable integration with the original temperature control system.
