The Stanford Research Systems PTC10 is a modular, programmable temperature controller delivering precision thermal management across scientific and industrial applications. The system architecture supports up to 16 input channels and 4 independent PID feedback control loops, each sampling at 50 Hz with 1 mK resolution. A 320 × 240 pixel touchscreen provides real-time numeric and graphical data display, while configurable alarms monitor upper/lower temperature limits and rate-of-change thresholds per channel with audio alert and relay closure outputs. Data logging to removable flash media enables long-term monitoring. The controller interfaces via USB, Ethernet, RS-232, and optional GPIB, making it suitable for laser diode stabilization, cryogenic measurements, materials research, and sensor-based thermal feedback systems.
