The Stanford Research Systems PTC10 Programmable Temperature Controller is a modular system engineered for precise temperature measurement, control, and data logging in laboratory and industrial environments. The main controller accommodates up to four I/O cards, enabling configuration of up to 16 input channels and 6 PID feedback control channels. The system resolves temperature to 1 mK with a 50 Hz PID sampling rate and features a 320 × 240 pixel touchscreen for numeric and graphical displays.
