PION400 combines pH, mV, ion and temperature measurement in the portable 400-series platform. Choose the ion-selective electrode and calibration method for the ion you need to report; the meter platform is distinct from a named-ion complete kit.

PION400 supports pX, mol/L, ppm and mg/L reporting, with built-in ion selections and a user-defined option. The connected electrode and method determine the usable concentration range and sample conditions.
A meter’s pX display range is not a universal detection limit for every ion. Select a compatible electrode, suitable standards and the correct conditioning solution for the sample.
The platform supports 0.00–14.00 pH at 0.01 pH resolution and ±0.01 pH ±1 digit meter accuracy. Automatic pH calibration supports one to three points.
The pH electrode’s own sample limits and care routine remain separate from the ISE method. Confirm the required electrode configuration before ordering this platform.
Ion activity, sample pH, temperature, interfering ions, contamination and the condition of the sensing membrane can all affect an ISE measurement. Prepare standards and samples consistently.
Use the appropriate one- to three-point ion calibration method. A concentration result is not automatically a total-element result after digestion or a direct reading of another chemical species.
Match the stated limits and configuration to your procedure. The Product Specifications tab repeats the order details for quick reference.

No. This is the base platform listing. Named-ion kits specify a particular sensing and calibration configuration.
Yes. PION400 adds pH measurement to the ion, mV and temperature platform, with an appropriate connected electrode.
Select the matching ISE, calibration standards and sample method. The meter’s ion selection alone does not make an electrode sensitive to another ion.
No. The usable ion concentration range and sample window are specific to the chosen electrode and method.
The catalog lists pX, mol/L, ppm and mg/L for ion reporting.
The platform supports one- to three-point manual ion calibration.
No. Different target ions require the appropriate selective membrane and sample-conditioning method.
Confirm the intended ion, electrode connection, calibration standards, conditioning reagents and exact packing configuration. Choose a named-ion kit for a defined complete setup.
