CX-LSM-1609A Laboratory Sodium Meter

 

CX-LSM-1609A is made based on the improvement of the previous pointer scale display, knobs, switches and non-intelligence design. It is equipped with the dedicated laboratory PPB sodium ion measurement electrode and the reference electrode, with the static measurement performance in the beaker greatly improved, compared with the traditional sodium meters. As long as the user pays attention to the electrode cleaning, the satisfactory result can be achieved. It can be widely used for continuous monitoring of sodium ions of the solutions in thermal power plants, chemical fertilizer, metallurgy, environmental protection, pharmaceutical industry, biochemical industry, foodstuff and running water.
