Lithium, Ionized Calcium, pH & Core Electrolytes – All in One Affordable Analyzer

The GHM M-900 Semi-auto H is a powerful, multi‑parameter analyzer that measures potassium (K⁺), sodium (Na⁺), chloride (Cl⁻), ionized calcium (iCa⁺⁺), normalized calcium (nCa), total calcium (TCa), pH, and lithium (Li⁺) – all from a single sample. It is the ideal choice for psychiatric units, ICUs, nephrology, and metabolic wards that need both therapeutic drug monitoring and critical care parameters.

Key Features

  • 7" Color Touch Screen
    Intuitive human‑machine interface – easy to learn and 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 – perfect for budget‑conscious hospitals and clinics.

  • Comprehensive Parameter Set – Model H Configuration

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

    • Sodium (Na⁺): 15.0–200.0 mmol/L

    • Chloride (Cl⁻): 15.0–200.0 mmol/L

    • Ionized Calcium (iCa⁺⁺): 0.10–6.00 mmol/L – bioactive form, essential for cardiac and nerve function

    • Normalized Calcium (nCa) – pH‑adjusted for accurate calcium assessment

    • Total Calcium (TCa)

    • pH: 4.00–9.00 – acid‑base status

    • Lithium (Li⁺): 0.10–6.00 mmol/L – therapeutic drug monitoring for bipolar disorder

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

    • K, Na, Cl, Ca⁺⁺, Li⁺ ≤1.5%

    • pH ≤2.0%

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

  • 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 results.

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

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

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