Model KL-167 Sodium Ion Concentration Meter is designed to measure sodium ion (Na⁺) content in aqueous solutions. It is particularly suitable for quality monitoring of high-purity water in power plants, including steam, condensed water, boiler feed water, and it can also be used for furnace water, natural water and other water samples. The KL-167 sodium ion concentration meter consists of a fully integrated circuit high-impedance millivoltmeter (hereinafter referred to as the meter) and a PNa combination electrode. When the PNa electrode is immersed in the sample solution, an electric potential will be generated, which depends on the activity of sodium ions. After the potential signal is transmitted to the millivoltmeter, the PNa value can be directly displayed on the instrument, and the corresponding sodium ion concentration can be obtained by checking the conversion table.

It is especially suitable for quality monitoring of high-purity water in power plants, such as steam, condensed water and boiler feed water, and can also be applied to furnace water, natural water and other water samples. The KL-188 sodium ion concentration meter consists of a fully integrated circuit high-impedance millivoltmeter (hereinafter referred to as the electric meter) and a PNa combination electrode. When the PNa electrode is immersed in the test solution, a specific electric potential is generated in the solution, which depends on the activity of sodium ions. After this potential signal is input to the millivoltmeter, the PNa value can be read directly on the display, and the corresponding sodium ion concentration can be checked from the attached scale table. Measuring Range Meter unit: PNa 0~9; Na⁺: 23 g/L ~ 0.023 μg/L Full set measurement (subject to electrode performance): PNa⁺: 1~7; Na⁺: 2.3 g/L ~ 2.3 μg/L Resolution 0.01 PNa Accuracy Meter only: ≤ ±0.02 PNa per 3 PNa Complete system: ±0.05 PNa ± 1 digit Stability 0.02 PNa per 24 hours High & Low Limit Alarm Accuracy 0.02 PNa Output Current 4~20 mA Calibration Mode Single-point calibration & two-point calibration Display 4-digit LED display Power Supply AC 220V ±10%, 50Hz ±2% Operating Environment Ambient temperature: 5 ~ 50°C Relative humidity: ＜85%
