SAFETY CONSIDERATIONS
PROCEDURE
ABB toroidal conductivity sensors are cleaned using one or a combination of

WARNING
1. Consider the material compatibility between cleaning fluids
and process liquids. Incompatible fluids can react with each
other causing injury to personnel and equipment damage.
2. Acids and bases can cause severe burns. Use hand and eye
protection when handling.
3. Use solvents only in well ventilated areas. Avoid prolonged
or repeated breathing of vapors or contact with skin. Solvents
can cause nausea, dizziness and skin irritation. In some cases,
overexposure to solvents has caused nerve and brain damage.
Solvents are flammable - do not use near extreme heat or open
flame.
