EZ-Zone PM 1/8 DIN has large characters and buttons to improve usability and is offered in horizontal or vertical configurations, allowing it to fit variable cabinet profiles. The case slots simplify removing the control hardware from the front pluggable DIN chassis by simply utilizing a screwdriver. It also offers advanced functionality such as dual channel PID control, cascade control, square-root linearization, wet bulb/dry bulb capability, ratio, and pressure-to-altitude compensation curves, which are not available with related 1/16 and 1/32 DIN controllers in the line. It can run a single profile ramp-soak program on dual channels simultaneously.
