We have a new version of the JTW Ultimate about to be released. It has an upgraded cooling system, the standard version is fixed at an absolute -15 degrees C (below zero, NOT below ambient). The pro version is fixed at 25 below zero. We are also working on a cryo version, that operates on the lower limit of the sensor, at 37.5 degrees below zero. These temperatures are all absolute and are not delta T values. Even the basic system has a delta T of 50 degrees, to handle the hottest days, and give consistant results all year round. These systems are fixed and need to no intervention, they just work completely transparantly!
