Designed for temperature control with ramp to setpoint and furnace and oven control, this temperature/process controller provides T/C, Heat. It has accuracy of ±0.2% of full scale, ± digit.
Designed for temperature control with ramp to setpoint and furnace and oven control, this temperature/process controller provides T/C, Heat. It has accuracy of ±0.2% of full scale, ± digit.
The CN8500 temperature controller is extremely versatile and user-friendly. The operator needs to review only those parameters relevant to the particular application during setup.
A dual digital display offers optimum process information at a glance. The dedicated upper display shows the process temperature, while the lower display displays setpoint and setup parameters.
