IntelliCAL™ ISECL181 is a digital, combination chloride ion selective electrode (ISE) with a non refillable, double junction reference and built-in temperature sensor. The solid-state sensor design eliminates membrane replacement and allows for dry storage of the ISE.

• Compatible with digital Hach meters only (e.g. HQd meters)
• Requires virtually no maintenance
• Fast, stable, and accurate results
• Ultimate traceability in measurement history
• Can be moved between meters without the need to re-calibrate or re-enter measurement settings

The probe is available with a 1 or 3 meter cable and is intended for laboratory use. Ideal for measuring chloride concentrations in wastewater, drinking water and general water quality applications.
