Repeated field testing on many types of optical surfaces under many conditions and thousands of satisfied customers have proven the effectiveness of Kendrick Astro Instruments' dew controllers over and over. Amongst other things, our system has these attractive features:

• Energy efficiency. Our controllers use almost zero power except for that required to illuminate the LEDs (which is VERY little!). Rather than use energy, our controllers actually conserve battery power by having programmable settings to control the heaters for precise application of heat. The systems are programmable with variable duty cycle, temperature variance, dewpoint variance or set temperature, depending on which controller you use.
• It is lightweight.
• High quality build. We use only the best quality components in our system, whether it be controllers or heaters. We do not compromise on the integrity or performance capabilities of our product.
• It will keep every optical surface you are using free of moisture in many different circumstances.
• High quality circuit boards in our controllers. We use "double sided" circuit boards. This gives our heater jacks extra strength to help prevent the solder breaks that will occur on single sided boards from the stress and strain of plugging and unplugging heaters.
