The DC205 low-noise, high-resolution DC voltage source is the right tool to use when a precision bias source is needed. Its bipolar, four-quadrant output delivers up to 100 V with 1 µV resolution and up to 50 mA of current.
The SR540 chopper will handle all your optical chopping requirements—from simple measurements to dual-beam and intermodulation experiments.
The PS300 series high voltage power supplies are rugged, compact, reliable instruments for just about any high voltage application.
The PTC10 programmable temperature controller is a modular system that can be configured to suit a wide range of applications. The system consists of the PTC10 controller and up to four I/O cards — two types of input cards for RTDs and thermocouples, and two types of output cards for driving heaters.
The CTC100 cryogenic temperature controller is configured to suit a wide range of research and industrial applications. The system consists of four sensor inputs, two powered and four analogue voltage outputs, and up to six feedback control loops.
