Lab Junction Na₂SO₃ & KCl Standard Solutions (100 ml Each) for Calibration of Dissolved Oxygen Meter, Model LJ-831(b)

for Calibration of Dissolved Oxygen Meter, Model LJ-831(b)

The Lab Junction Na₂SO₃ & KCl Standard Solutions (100 ml Each) are ready-to-use calibration reagents designed for precise calibration of Dissolved Oxygen (DO) Meters, including Model LJ-831(b). These high-purity Analytical Reagent (A.R.) grade solutions ensure precise, repeatable, and reliable dissolved oxygen readings in laboratory and field analysis. The Sodium Sulfite (Na₂SO₃) solution helps establish zero oxygen conditions, while the Potassium Chloride (KCl) solution maintains electrode conductivity and stability during calibration. Ideal for water testing, research, environmental monitoring, and quality control laboratories, these solutions comply with standard laboratory quality norms and are supplied in sealed 100 ml bottles for convenience and accuracy.
