The remote sensor contains no bi-metallic contacts to arc, corrode, or wear out. This allows the HMS heaters to have precise control, keeping the water temperature stable while avoiding wide temp swings common with many other aquarium heaters.Advanced Temp SensorThe remote sensor also functions as an automatic power cut-off switch. If the water level drops too low and exposes the temp sensor to air, the power to the heater tube is turned off. This prevents accidental over-heating due to a loose sensor reading room temps.Durable and Reliable Heating ElementThe heating element is constructed of corrosion-resistant titanium, making it virtually unbreakable. The heating element also comes with a protective heater guard which prevents fish and other equipment from coming into contact with the heating tube.Heaters are by far one of the most important pieces of equipment on any reef tank. Finnex has been making high quality, compact electric, titanium heaters for years and allow you to create a safe and very stable temperature within the tank.Finnex HMS Heater Comparison ChartModelWattageAmpControl RangeTank SizeTube LengthHMS 50S50.4550 – 94°F10 – 20 gal6.30″HMS100S100.950 – 94°F21 – 30 gal7.26″HMS 150S1501.3550 – 94°F31 – 60 gal8.46″HMS 200S2001.850 – 94°F61 – 80 gal11.22″HMS 300S3002.750 – 94°F81 – 100 gal12.40″HMS 500S5004.550 – 94°F101 – 120 gal15.16″What’s Included?Finnex HMS Heater w/Digital Controller
