The SmartBob II High Temperature remote is for applications where the process temperature is between 240° and 500°. This model is built with components designed to safely operate in temperatures up to 500°. A Stainless steel standpipe is used to extend the remote away for the heat source and a Stainless Steel pipe extension fitted with a Teflon cable guide keeps the sensor probe out of the standpipe and level with the vessel top. An air purge nipple is standard to allow a small amount of air to circulate through the mechanical cavity of the remote.
