CSM_BF- @ (R)/BS-1(T)_DS_E_8_3 

## **Electrode Holder BF-** @ **(R)/BS-1(T)** 

## **Complete Lineup for Use in High-temperature, High-pressure Environments or Where Exposed to Chemicals** 

- The BF-1 is ideal for liquids with low specific resistance, such as wastewater. 

- The BF- @ (R) is used when a strong mounting is required. 

- The BS-1 is used when high-temperature, high-pressure resistant is required. 

- The BS-1T is used when corrosion resistance is required.

- **Note: 1.** Two-wire Electrode Holders (R models) have a built-in resistance of 6.8 k Ω . 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.
