Us About Us Temperature Control Products Model 34 Cryogenic Temperature Controller. The Cryo-con Model 34 is an Autotuning Cryogenic Temperature Controller. Four multipurpose input channels are available that can be independently configured for Diode, Thermocouple, Platinum and most other cryogenic resistor sensors.
Resistance is measured using a ratiometric constant-current bridge technique.
AC excitation removes DC offsets. Dual-loop operation is supported using a 50W, four range linear heater and a second 400mW output. Download Datasheet in PDF Format.
