measuring principle
The ion sensor can realize the flexible selection of one or two ion selection electrodes, and the default standard PH and temperature electrodes, realizing simultaneously monitoring the four parameters. The optional parameters of the ion selection electrode include: ammonium ion (NH4 +), nitrate ion (NO3-), potassium ion (K +), chloride ion (CL-), and fluoride ion (F-). Different parameter combinations can also realize the role of mutual compensation, making the measurement data more accurate.
functional characteristics
Choose one or two electrodes in ammonium ion, nitrate ion, potassium ion, chloride ion or fluoride ion. Realize flexible combination to meet the needs of different customers.
