• Utilizes a unique solid-state sensor technology that eliminates costly membrane replacements. – Traditional PVC-membrane ISEs require membrane replacement every 2-3 months. The Intellical ISENH4181 Ammonium ISE’s unique solid-state sensor technology eliminates the need for frequent membrane replacement by using a solid gel ion exchange behind the ion-selective membrane versus the liquid ion exchange used in most ISEs. This design allows users to get up to 2 years of life from their ISE without membrane replacement – saving the time and costly expense of frequently exchanging membranes.
• Requires virtually no maintenance – The solid-state sensor design allows for DRY storage of the ISE without a shelf life. Also, the probe does not require the electrolyte to be refilled.
• Fast, stable, and accurate results – Intellical digital probes lock on the result when the measurement is stable, removing the guesswork in having a moving number. Additionally, the probe’s large annular reference junction provides maximum surface area between sample and reference electrolyte for fast measurement stability. And the solid-state sensor design doesn’t allow the membrane to flex or undergo surface area changes, leading to more stability in results over a variety of samples.
• Ultimate traceability in measurement history – Stored time and date stamp for each measurement, operator and sample ID, calibration history, parameter, and probe serial number
• 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
