GHM M-900 Semi-auto A Electrolyte Analyzer #

Simple, Reliable & Cost‑Effective – Measure K, Na, Cl with Ease

The GHM M-900 Semi-auto A is a compact and affordable electrolyte analyzer designed for serum, plasma, whole blood, and dilute urine samples. It focuses on the three core electrolytes – potassium (K⁺), sodium (Na⁺), and chloride (Cl⁻) – making it the perfect entry‑level choice for small clinics, rural hospitals, and labs that need essential electrolyte testing without unnecessary complexity.

Key Features

• 7" Color Touch Screen
  User‑friendly human‑machine interface for simple, intuitive operation. No extensive training required.

• Low Cost of Use – Fast ROI
  Consumables cost only a fraction of imported alternatives. Most users recover their investment in a short time – ideal for budget‑conscious facilities.

• Measures K, Na, Cl – Core Electrolytes
  Model A configuration provides reliable results for the three most frequently ordered electrolytes.

  • Potassium (K⁺): 0.50–20.00 mmol/L

  • Sodium (Na⁺): 15.0–200.0 mmol/L

  • Chloride (Cl⁻): 15.0–200.0 mmol/L

• High Precision
  Ion‑selective electrode (ISE) technology with CV ≤1.5% for all three parameters. Measuring time ≤40 seconds.

• Compact & Lightweight
  Dimensions: 334 × 252 × 365 mm, Net weight: only 5 kg – reduces shipping costs and fits easily on any lab bench.

• Auto Flushing After Each Sample
  Automatically flushes the system to keep electrodes in optimal condition, extending electrode life and reducing maintenance.

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

• Blockage Prevention & Cross‑Contamination Control
  Original wave flushing and direct injection tube design reduce clogging and cross‑pollution, ensuring accurate results.

• Error Warnings & Auto Troubleshooting
  The system alerts you to issues and guides troubleshooting, enhancing workflow efficiency.

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

• Sleep Mode
  Reduces reagent consumption when not in use – saves money and extends consumable life.
