The 6400 is one of the most powerful 1/16 DIN size profilers available anywhere. In addition to a 4 recipe, 16 free-format segment profiling capability, it features West's proven RaPID (Response assisted PID) control algorithm, which provides fast accurate control with simple set-up and use.

The 6400 allows you to save up to 4 programs in memory. Each segment can be either ramp or dwell. Programming can be in rate or time mode and the guaranteed soak feature protects the quality of your product by waiting until the PV is in range before starting a dwell. A delayed start can be programmed through the front panel. Profile recovery allows you to re-start midway through a profile or begin again in case of interruption. Program active relay, event outputs and remote start are all available as options.

The 4400 is a 1/4 DIN size profiler that can create a profile with anything from 1 to 121 segments. It can store up to 8 programs in the instrument, and uses West's dedicated software package to configure and store extra programs on a PC. The 4400 features a sophisticated 'Auto Hold' facility which allows users to specify their own 'guaranteed soak' or 'track and hold' procedures, putting the profile 'on hold' if the actual temperature or process variable deviates from the operator's fixed parameters. Options include remote run hold, remote program select, 4 event outputs, real-time clock and power failure recoveries all of which add to the sophistication of this product.

The 4400 will enable the operator to see what the measured variable is and what set point is in use at any one time. It will show the number of cycles or time remaining in a designated profile, and whether the cycle is in ramp or dwell. It even allows you to save recipes by name or number and show these on the 8 character alpha-numeric display.
