Heatable dew cap by Lacerta

Lacerta dew caps have following advantages:

 - Long velcro tape which helps to fit one dew cap to several tubes

- Bult-in dimmable heating, thus applicable under different conditions during Summer and Winter as well

- Matte inner side since main function is to lock out shining from sides

- Flexible but strong build prevents break during cold nights and helps easier packing after finishing work

- Easy to read thermometer to avoid overheating and wasting power

Controlling the device:

- Plugging direct into power source so the heating is always at full power. This solution sounds easy however hard turbulence can occur if the temperature difference is too big relative to the environment.

- Adding a simple pot (or any dimmer made for LEDs) between the can and power source gives manual control over heating power

- Utilizing Lacerta deltaT does control automatically. Just put the thermal sensors in place, set the wanted thermal difference and everything else is controlled automatically.
