KL-188 Sodium Ion Concentration Meter

Product Description: The KL-188 Sodium Ion Concentration Meter is designed to measure the Na+ content in aqueous solutions, particularly suitable for monitoring the quality of high-purity water in power plants (such as steam, condensate, boiler feed water, etc.). It can also be applied to other water types like boiler water and natural water. The KL-188 Sodium Ion Concentration Meter consists of a fully integrated high-impedance millivoltmeter (hereinafter referred to as the meter) and a PNa combination electrode. When the PNa electrode is immersed in the test solution, a specific potential is generated, which depends on the activity of Na+. This potential is input into the meter, allowing direct reading of the PNa value and determination of the Na+ content from the scale.
Measuring range: (1) PNa for the electrical part: 0–9; Na+: 23g/L–0.023μg/L. (2) Matched measurement (depending on electrode performance) PNa+: 1–7; Na+: 2.3g/L–2.3μg/L. Resolution: 0.01PNa. Accuracy: (1) Electrical part: ≤±0.02PNa/3PNa. (2) Matched: ±0.05PNa±1 digit. Stability: 0.02PNa/24h. Upper/lower limit alarm accuracy: 0.02PNa. Output current: 4–20mA. Calibration: Single-point and two-point calibration. Display: 4-digit LED display. Power supply voltage AC: 220V±10%, 50Hz±2%. Operating environment: Ambient temperature 5–50℃, humidity <85%.
