Eurotherm Controls has added an improved timer function to its series 2100 temperature controllers. The instruments can apply heating or cooling for a pre-set period or delay heating until a pre-set time. Delay in heating is important for over-night batch processing or repetitive heating/cooling cycles. The instruments are also available in either 1/32 or 1/16 DIN panel sizes and each has two outputs. The enhanced timer offers five different operating modes, including simple ramp-dwell programming, timed heating and cooling and delayed switch-on heating and cooling processes.
