Industry Applications

Maintenance & Resale

Maintenance Schedule:

• Monthly: Burette seal inspection (replace after 5,000 tests)
• Quarterly: Electrode calibration (slope ≥95%)
• Annual: Full validation (OEM standards required)

Resale Evaluation:

1. Critical Components:
   • Touchscreen integrity (no scratches/malfunctions)
   • Burette piston wear (max 0.01mm clearance)
2. Accessories:
   • Original electrodes (e.g., 6.0133.100)
   • Valid calibration certificates
3. Market Value:
   • Base model (single channel): ¥80k-120k
   • Advanced (dual channel + KF): ¥150k-220k

Service Support

• Response Time: 24-hour emergency service in major cities
• Consumables:

  Item	OEM Price	Lifespan
  Titration electrode	¥3,800	1 year/2,000 tests
  Burette assembly	¥6,500	3 years/50k doses
