Digital temperature controller MercuryiTC

multi-channelPIDprogrammable

A cryogenic programmable intelligent temperature controller. Features • Measures and controls temperatures to below 250 mK with a precision of 0.1 mK (24 bit A to D resolution). • Heater output up to 80 W per channel. • Software switchable between true constant voltage source or current source for sensor excitation, preventing self-heating and allowing for high quality measurements at the lowest temperature. • Supports all standard cryogenic sensors (ruthenium oxide, cernox, silicon diodes, platinum, thermocouple and RhFe). • Base system includes a single temperature sensor input and 80 W heater output for precise temperature PID control. • Easy pc connection to your Mercury instrument via multiple remote ports. • The MercuryiTC has also a number of pre-configured control modes e.g., Heliox control, Lambda Fridge control, Rotator control, etc. • Rear panel connections.
