Tetra HT 100W is a fully electronic, submersible aquarium heater designed to maintain a stable water temperature for tropical fish. Its integrated microprocessor provides precise temperature regulation, with an adjustable range of 20°C to 32°C. The heater features a three-stage LED indicator to display its operating status, a thick heat-resistant and shock-resistant borosilicate glass tube, a protective plastic cap, and an automatic safety shut-off function. Supplied suction cups allow secure attachment to the aquarium glass.
