Questions about this product? ↗The STAPERM™ ZN-4-PT is a portable zinc/zinc sulfate reference electrode for field potential measurements. Its red ABS housing identifies the electrode chemistry.
Technology and construction
A porous ceramic contact plug couples the reference electrolyte to the test surface. The portable housing and threaded connection stud provide a convenient arrangement for moving between measurement locations with a field meter.
Key advantages
- Serviceable construction: The portable series uses a rechargeable design for continued field use.
- Ceramic contact plug: Provides the contact interface for repeatable positioning at measurement locations.
- Field-ready housing: High-impact ABS protects the assembly during routine handling, with color coding to identify the chemistry.
Applications
Routine cathodic protection field checks, structure-to-electrolyte potential measurements and survey work where the selected reference chemistry is appropriate.
Technical specifications
- Contact plug: round or pointed ceramic, selected above.
- Housing: high-impact ABS, 1 in. diameter × 8 in. long.
- Connection stud: 1/4 in.-20 plated brass.
- Stability: ±10 mV with a 3.0 µA load.
- Operating temperature: 32°F to 135°F (0°C to 57.2°C).
