RTDCAP Platinum RTD Capsules 09266

 Ready to use platinum RTD capsules have insulated lead wires welded and anchored internally. No splicing to fragile elements is required. This construction assures reliable rugged embedment, insertion or probe assembly. Tip diameters from 0.086 to 0.125". Standard sensors and encapsulation materials rated up to 540°C (1000°F). Choose the moisture resistant version for condensing conditions.
