Probe anodes are an effective solution for protection the internal surfaces , it adopts MMO or platinum coated solid titanium rod can be operated in high voltage without breaking down. UTron manufacture mixed metal oxide probe anodes and platinum coated probe anode. They are composed of titanium rods coated with a layer of mixed metal oxide or platinum coating. This probe anodes can withstand water turbulence without damage, the coating is immune to abrupt current reversals, and may be exposed to high-current overloads for initial structure polarization without causing harm to the anode.They have been found to be resistant to acid attack and deliver superior protection in fresh, brackish, or saltwater. They are available in a wide variety of sizes and configurations. Parameter: Anode diameter: 6.4mm, 12.7mm or customize; Anode material: titanium in Grade 1 or 2; Coating: Mixed metal oxide or platinum; Service Life: Over 20 years. Feature: Advanced sealing with multiple layers of p
