KL-188 Sodium Ion Concentration Meter

The KL-188 sodium ion concentration meter is designed to measure sodium ion
(Na⁺) content in aqueous solutions. It is especially suitable for quality
monitoring of high-purity water in power plants, such as steam, condensed
water, boiler feed water, and also applicable to boiler water, natural water
and other water samples.
This instrument consists of a full-integrated high-impedance millivoltmeter 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
sodium ions. After the potential signal is transmitted to the millivoltmeter,
the PNa value can be directly displayed on the meter, and the corresponding Na⁺
concentration can be checked via the conversion table.
