产品描述
The CY325 Series dual-channel temperature controller is capable of supporting nearly any diode, RTD, or thermocouple temperature sensor. Two independent PID control loops with heater outputs of 25 and 2 W are configured to drive either a 50 or 25 ù load for optimal control flexibility. Designed with ease of use, functionality, and value in mind, the CYC325 Series is ideal for general-purpose laboratory and industrial temperature measurement and control applications.
