ATC/MTC temperature compensation
  • Multi-reading: auto-read (fast/medium/slow), timed and continuous
  • Reading prompts: Reading / Stable / Locked; Auto-hold endpoint
  • Automatic electrode diagnosis (slope & offset); slope limit; calibration reminder

Key features

  • 7.0″ color high-contrast LCD touchscreen.
  • 1–6-point calibration with standard recognition (NIST, GB, DIN, USA, MERCK, JIS) and custom buffer groups.
  • ATC/MTC ensures accurate results across temperature changes.
  • ORP/mV: ±2000.00 mV range; 0.1/0.01 mV resolution; ±0.1 mV or ±0.03% accuracy; EH mode; 1-point relative mV calibration.
  • GLP-compliant data: up to 1000 groups; log management; date/time stamps; data analysis and recall.
  • Connectivity: USB 2.0 (flash / PC / scanner) and RS-232 (printer / autosampler).
  • Reset to defaults; IP54 splash/dust protection.

Typical applications

  • Water & wastewater labs (drinking, process, effluent)
  • Food & beverage QC, dairy, agriculture
  • Pharma & biotech buffers, process control
  • Education & research laboratories
