✅ Key Features & Specifications

Measured parameters / Principle:

• Measures ions: Na⁺, K⁺, Cl⁻, iCa⁺⁺ (and sometimes Li⁺ or pH) using Ion-Selective Electrode (ISE) technology.

• Sample types: whole blood, serum, plasma, urine (and occasionally CSF).

Performance & workflow:

• Sample volume: approximately 90–100 µL.

• Analysis time: less than 60 seconds per sample.

• Throughput: up to 60 samples per hour.

• Calibration: automatic two-point calibration every 4, 8, or 12 hours (user-selectable) and optional one-point calibration per sample.

• Built-in quality control: includes tri-level QC, 30-day QC history, and Levey–Jennings (L-J) plots for QC trend monitoring.

Display & Interface:

• 5-inch colour LCD touchscreen (approx. 480 × 272 resolution).

• Built-in thermal printer (48 mm paper width, 42 characters).

• Interfaces: USB ports (for keyboard, mouse, barcode reader, or flash drive) and RS-232 serial port.

Physical & Environmental:

• Dimensions: around 365 × 255 × 375 mm (some variants 395 × 260 × 375 mm).

• Weight: roughly 5 – 7.5 kg depending on model.

• Operating conditions: 15 – 35 °C ambient temperature, ≤ 85 % relative humidity (non-condensing).

• Power: 100 – 240 VAC ± 10 %, 50/60 Hz.

Performance precision (typical):

• Coefficient of variation (CV %) — Na⁺, K⁺, Cl⁻ ≤ 2 %; iCa⁺⁺ ≤ 3 %.
