How and Why
Game Changer on these applications
1
Quantum Research
The TC-2 controls temperatures down to 300 millikelvin, which is essential for experiments that require access to the quantum regime.
With a PID control outputs and 2 inputs, you can independently manage:
-Sample temperature
-Cold plate temperature
2
Astrophysics & Space Instrumentation
Commonly used in cooling and monitoring infrared detectors, bolometers, and other instruments in telescope and space mission development.
3
Superconducting Magnet Systems
Precise control of cool-down and operating temperatures for superconducting magnets (e.g., in NMR, MRI, or particle physics experiments).
Prevents thermal overshoot that could damage sensitive equipment
4
Condensed Matter Physics
Measuring properties of exotic phases of matter like topological insulators or fractional quantum Hall states.
5
Liquid hydrogen infrastructures
Up to 2 sensor inputs, so you can track temps at various critical points (tank wall, inlet/outlet, vapor phase, etc.) temperature variations in liquid hydrogen systems.
With PID loops, it can manage heaters, bypass valves, or thermal shields to stabilize or control boil-off
