DewNot 3" Dew Heater Strip DN004
Made in the USA, the Dew-Not Dew Remover is a thick film dew heater manufactured for operation at 12 volts. It helps keep dew condensation from forming on the glass surface of your optical device.
SELECTING A DEW HEATER: To select the right dew heater for your scope, measure the circumference of your specific eyepiece/finder/telescope tube or dewshield. Or measure the tube/dewshield diameter - not telescope aperture - and multiply by 3.14. Pick one of the models based on the length specified. For in-between sizes, choose the next larger size of dew heater. Please measure and select the correct size BEFORE ordering, and please do NOT order blindly based on your telescope aperture as tubes
POWERING A DEW HEATER: Note that all Dew Not Dew Heaters come with a male RCA (phono plug) power jack. To power these, you need a separate 12V power supply source with a female RCA/phono plug connector. You cannot run these directly from 110/220V AC, USB, or cigarette-lighter sockets and no other power cords are included. Several companies (like Dew-Not, Thousand Oaks, Kendrick, etc.) sell dew controller units that can power and control these heater strips, or you can also look for other 12V bat
