A thermostat dial sets the target between 68 °F and 92 °F, and the heater switches on when the surrounding water drops below that setting and off again once it reaches it. The 2 mm quartz glass tube protects the element, and the package includes an LED thermometer with a three-digit display.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e300W heater for betta tanks in freshwater and saltwater\u003c\/li\u003e\n\u003cli\u003eTemperature dial adjustable from 68 °F to 92 °F\u003c\/li\u003e\n\u003cli\u003e2 mm thickened quartz glass tube\u003c\/li\u003e\n\u003cli\u003eETL certification\u003c\/li\u003e\n\u003cli\u003eLED three-digit display thermometer included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGlass tube, suction cup and double seal\u003c\/h2\u003e\u003cp\u003eThe heater body sits inside a quartz glass tube that is 2 mm thick, and a bottom protective cover shields the lower end of the tube. A suction cup holds the heater in place on the tank wall. A double seal closes the tube around the element, and the joints are precision welded. A working indicator light shows when the heater is running.\u003c\/p\u003e\u003cp\u003eThe temperature scale guide bar sits alongside the dial, so the set point lines up with the markings when you turn it.

A tank that needs to sit below 68 °F or above 92 °F falls outside the range.
