*1. Two-wire Electrode Holders (R models) have a built-in resistance of 6.8 kΩ. They should be used with the Two-wire
       61F Controllers.
*2. Vapor leakage may occur when used outside of the specified operating temperature and pressure range.
       Use the Electrode Holder within the specified maximum operating temperature and pressure range according to the
       following pressure-temperature curve.
