2. Overview of the Mark II Controller
The Mark II is a simple, easy-to-operate sterilizer control system. It allows selection of
sterilizer cycles, setting of temperature, and times for Sterilization and Dry. It displays
status of the machine in sterilize or exhaust modes, executes selected cycles, and prints a
chart of sterilizer temperature vs. time. Figure 2.1 shows a typical Mark II controller
with a chart recorder.

2.1 Description
The Mark II controller was designed with simplicity of operation in mind. The controller
allows setting of sterilization time and dry time (for a Dry cycle only). LEDs on the
controller show when the machine is in the sterilize mode and when it is in the exhaust
mode. A selector switch (see Figure 2.1) allows user to select one of three types of
cycles: Fast, Fluid, & Dry. A pressure gauge shows the current steam pressure inside the
chamber of the sterilizer. A chart recorder records a graph of time vs. temperature during
the cycle. For Low-Temp equipped sterilizers, please see section 4.3.
