The Newport 350 Temperature Controller is a precision instrument for accurate temperature monitoring and regulation of thermoelectric (TE) modules in laboratory and research environments. It employs a hybrid P-I control loop to maintain stable performance across demanding optical and electronic applications. The controller operates three distinct modes—constant resistance, constant temperature, and constant TE current—with user-adjustable current limiting to protect TE modules during operation.
