* Please consult before ordering
IntelliCALⓇ ISENH3181 is a digital, combination gas-sensing, ammonia ion selective electrode (ISE) with a with a replaceable membrane module, refillable outer body, a non-refillable gel 3M KCl reference with a double junction porous PTFE annular ring and built-in temperature sensor. The electrode measures ammonia concentration in water samples. A 50 mL bottle of 0,1 M NH4Cl Electrode Filling Solution is included with the probe.The laboratory version of this ISE is shockproff with its Epoxy plastic body.The IntelliCAL ISENH3181 probe is available with a 1 or 3 meter cable and is intended for laboratory use. The ISENH3181 is ideal for measuring ammonia concentrations in wastewater, drinking water and general water quality applications.
Benefits
Provides fast, stable, and accurate results
Refillable outer body, an easy to maintain modular membrane design, and a large annular reference junction for maximum surface area between sample and reference electrolyte provide great measurement stability. 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 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
