Lake Shore 336

The Lake Shore 336 is a precision temperature controller operating from 300 mK to 1505 K, engineered for cryogenic and high-temperature research environments. It consolidates multiple instruments into a single platform, reducing bench footprint while delivering independent PID control loops, four sensor inputs with 24-bit resolution, and up to 150 W total heater output. Computer control via Ethernet, USB, and IEEE-488 enables full automation of temperature management across demanding laboratory and industrial setups.
