R800-6/R800-7 Platinum/Cobalt Industrial Resistance Thermometers for Very Low Temperature
R800-6/R800-7 are temperature sensors for very low temperature, which use platinum/cobalt dilute alloy for thermosensitive element and that can measure cryogenic temperature region (4K) to normal temperature precisely by one sensor.
