Labotronics Electrolyte Analyzer LB-11ELA uses ion-selective electrode (ISE) technology to measure K⁺, Na⁺, Cl⁻, Ca²⁺, pH, Li⁺, and TCO₂. It features a direct measurement method with a sample capacity of 300 µL for electrolyte and blood gas analysis. Automatic and manual calibration modes support consistent testing performance. Its graphic lattice LCD, built-in diagnostic system, and storage capacity of 1,000 or more samples facilitate clinical testing.
