IntelliCALⓇ ISENa381 is a digital, combination, sodium ion selective electrode (ISE) with a refillable double junction reference and built-in temperature sensor. The electrode measures sodium concentration in water samples. A 59 mL bottle of 0.02 M NH4Cl Electrode Filling Solution is included with the probe.The laboratory version of this ISE is shockproff with its Zeonor plastic body.The IntelliCAL ISENa381 probe is available with a 1 or 3 meter cable and is intended for laboratory use. The ISENa381 is ideal for measuring sodium concentrations in wastewater, drinking water and general water quality applications.
Benefits
Provides fast, stable, and accurate response
Refillable, easy to maintain design with a unique built-in-temperature sensor. IntelliCAL digital probes lock on the result when the measurement is stable, removing the guesswork in having a moving number.
Ultimate traceability in measurement history
Stored time and date stamp for each measurement, operator and sample ID, calibration history, parameter, and probe serial number.
User alerted when re-calibration is needed
No guesswork needed to provide the most reliable and accurate results with each measurement.
Can be moved between meters without the need to re-calibrate or re-enter measurement settings
Ideal for a multi-user environment with multiple HQD series Laboratory and Portable meters.
