The Lake Shore 330 is an autotuning temperature controller for precise cryogenic and scientific temperature monitoring and control. It supports multiple sensor input types with dual sensor inputs for simultaneous data display, offering stable regulation down to 100 mK with control stability to ±2.5 mK. The instrument features five tuning modes, programmable PID parameters, and ten custom temperature zones, with temperature display in Kelvin, Celsius, or sensor units (V, mV, Ω). All measurements are NIST-traceable and each unit is tested to published specifications at shipment.
