MMR Temperature Controller

MMR's K-20 Programmable Temperature Controller, when used with MMR micro miniature refrigerators, provides controlled cycling and temperature measurement over a range from 20 K to 400 K. It is designed to be compatible with RS-232C and IEEE-488(GPIA) interfaces. It may be operated with any personal computer with an available serial port using MMR's Windows-based software, or with MMR's handheld intelligent keyboard /display controller.
