Dedicated Lithium Monitoring with Potassium & Sodium – Compact & Affordable

The GHM M-900 Semi-auto E is specifically designed for serum, plasma, whole blood, and dilute urine samples. It measures potassium (K⁺), sodium (Na⁺), and lithium (Li⁺) – the essential combination for therapeutic drug monitoring in bipolar disorder patients, alongside routine electrolyte management. Perfect for psychiatric clinics, toxicology labs, and general hospitals.

Key Features

  • 7" Color Touch Screen
    Simple, intuitive human‑machine interface – easy to operate with minimal training.

  • Low Cost of Use – Fast Return on Investment
    Consumables cost a fraction of imported alternatives. Most users recover their investment quickly – ideal for budget‑conscious facilities.

  • Measures K, Na & Li – Optimized for Lithium Therapy
    Model E configuration provides accurate results for:

    • Potassium (K⁺): 0.50–20.00 mmol/L

    • Sodium (Na⁺): 15.0–200.0 mmol/L

    • Lithium (Li⁺): 0.10–6.00 mmol/L – covers sub‑therapeutic, therapeutic, and toxic levels

  • High Precision Across All Parameters
    Ion‑selective electrode (ISE) technology. Measuring time ≤40 seconds.
    Precision (CV%):

    • K, Na ≤1.5%

    • Li⁺ ≤1.5% (per M-900 brochure)

  • Compact & Lightweight
    334 × 252 × 365 mm, only 5 kg – reduces shipping costs and saves bench space.

  • Automatic Flushing After Each Sample
    Keeps electrodes clean and in good condition, extending electrode life and reducing maintenance.

  • Large Data Storage
    Stores up to 10,000 test results with power failure protection – never lose patient or QC data.

  • Blockage Prevention & Cross‑Contamination Control
    Original wave flushing + direct injection tube design minimizes clogs and cross‑pollution for accurate lithium results.

  • Error Warnings & Auto Troubleshooting
    Alerts you to issues and guides problem‑solving – improves workflow efficiency.

  • Connectivity Ready
    RS‑232 port for LIS connection. Print QC graphs and statistics for hospital management.

  • Sleep Mode
    Reduces reagent consumption when idle – saves money and extends consumable life.
