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.

Specifications
Note: 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.
Refer to Safety Precautions for Electrodes and
Electrode Holders.
