01 · Start with the actual sample
Evaluate target ions, range, compensation and interference together
Ion-selective response depends on the water matrix, pH, temperature and interfering ions. A reliable quotation needs the complete duty, not only a maximum range.
Range and water matrix
Provide minimum, normal and peak concentrations plus surface water, groundwater, process water or wastewater.
Compensation and interference
State pH, temperature, coexisting ions, solids, bubbles, fouling and maintenance conditions.
Mounting and interfaces
Confirm mounting, cable, power, 4–20 mA, relays, RS485, quantity and destination.
02 · Product model
PISE-900 online multi-ion analyzer
Configured with a black FUNEL single-parameter transmitter and composite ion sensor, with three 4–20 mA outputs, three relays and Modbus RS485.
Configurable ion-selective electrode systemPISE-900Online Multi-Ion Analyzer
A configurable online ion-selective platform that combines one or two application-specific ion electrodes with standard pH and temperature measurement, allowing up to four parameters in one project configuration.

03 · Operating applications
Typical ion monitoring applications
For ammonia nitrogen, nitrate nitrogen, potassium, chloride or fluoride monitoring in surface water, groundwater, industrial process water and wastewater.
Surface water
Configure the required ion electrodes for continuous environmental-water monitoring.
Groundwater
Track selected ionic parameters together with pH and temperature.
Industrial process water
Integrate application-specific ion data into process and discharge controls.
Wastewater treatment
Monitor ammonium, nitrate or other selected ions at treatment-process points.
04 · Common questions
Confirm this information before an inquiry
Which ions can PISE-900 select?+
Choose one or two electrodes from NH₄-N, NO₃-N, K⁺, Cl⁻ and F⁻, with standard pH and temperature electrodes.
Can it measure all five ions at once?+
No. The source states one or two selectable ion electrodes plus pH and temperature, for up to four parameters.
Why is water-matrix information required?+
pH, temperature, coexisting ions and fouling affect electrode configuration, compensation and maintenance.
Can the website image replace a dimensional drawing?+
No. It is for consistent public presentation. The Ø55 × 342 mm sensor and 145 × 125 × 162 mm transmitter dimensions remain controlled by the datasheet and project confirmation.
