About ions : Characteristics of our ion electrode products

1. Wide measurement range

It also varies depending on the type of electrode. Usually, it can measure from 10-7 to 100mol/L.​ The lower limit of measurement varies slightly depending on the measurement conditions and electrode history. Pay attention to maintenance.

2. Fast operation

It generally stabilizes in a few tens of seconds, but it takes three minutes in the case of a diaphragm electrode.
When the ion concentration shifts from lower to higher, it tends to be faster, and when it is reversed, it tends to be slower. In addition, it may not be constant due to the influence of the ion electrode history or the junction condition of the reference electrode.

3. Abundant ion electrode lineup

Including nitric oxygen and ammonia, it is possible to actually measure 20 kinds of ions.

4. Excellent selectivity

Although our ion electrodes exhibit excellent selectivity, they do not have any effect of coexisting ions at all. Depending on the coexisting ions, measurement errors may occur as well as deterioration of their characteristics. We recommend that you use them well by familiarizing yourself with their effects.
