Electrode Holder
BF-@(R)/BS-1(T)
CSM_BF-_(R)_BS-1(T)_DS_E_7_1
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.
Refer to
Safety Precautions for Electrodes and
Electrode Holders.
