*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. There must be a sufficient ambient temperature in a high-pressure environment to prevent vapor leakage. Use the
       Electrode Holder according to the following pressure-temperature curve.
