SOBO HC Stainless Steel Aquarium Heaters

SOBO HC Stainless Steel Aquarium Heaters

SOBO HC Stainless Steel Aquarium Heaters are submersible aquarium heaters built to give fish keepers steady, adjustable temperature control in the home aquarium. The HC Series pairs a 304 stainless steel body with a bimetal temperature sensor, so it is a practical, hard-wearing choice for hobbyists who want dependable heating through South Africa's cooler months and cold snaps.

Key Benefits

• Imported 304 stainless steel construction with strong corrosion resistance, suited to long-term use underwater.
• Imported bimetals known for their sensitivity, for responsive and precise temperature readings.
• Adjustable temperature range of 20-34 °C with an accuracy of ± 1 °C.
• A high-resistance heating wire inside delivers uniform, stable heating and is designed for a long service life.
• Efficient heat distribution helps create a comfortable, consistent environment for your aquatic life.
• A double waterproof sealing ring and an IP68 waterproof grade mean the heater is designed to be fully immersed in water, which helps minimise risk during operation.
• Slim 3 x 3 cm profile across the range, so the heater is easy to tuck away in the tank.
