Model KL-167 Sodium Ion Concentration Meter

The KL-188 sodium ion concentration tester is professionally designed to detect
sodium ion (Na⁺) content in aqueous solutions. It is widely adopted for high-
purity water quality monitoring in power plants, applicable to steam, condensed
water, boiler feed water, boiler circulating water and natural water.
This instrument is composed of full-integrated circuit high-impedance
millivoltmeter and matched PNa combination electrode. When the PNa electrode is
immersed in liquid sample, potential signal generated according to sodium ion
activity will be transmitted to the electric meter. The screen directly
displays PNa value, and users can check corresponding sodium ion concentration
via conversion table.
