硝酸鹽離子水質分析儀 HQ440D Lab Nitrate (NO₃⁻) Ion Meter Package with ISENO3181 Ion Selective Electrode
產品編號：8508100
Designed for water quality experts, the Hach HQ440D Laboratory Multi-Meter is an advanced laboratory meter that takes the guesswork out of measurements. HQD meters connect with smart IntelliCALⓇ electrodes that automatically recognize the testing parameter, calibration history, and method settings to minimize errors and setup time. The advanced HQD Laboratory Meter is designed to withstand years of continuous lab use. HQD meters feature a simple user interface that does not require manuals or training to operate. The IntelliCAL ISENO3181 is a digital, combination nitrate ion selective electrode (ISE) with a non-refillable, double junction reference and built-in temperature sensor. The IntelliCAL ISENO3181 electrode is intended for laboratory use. The ISENO3181 is ideal for measuring nitrate concentrations in wastewater, drinking water and general water quality applications. The ISENO3181’s solid-state sensor design eliminates membrane replacement and allows for dry storage of the ISE.

Utilizes a unique solid-state sensor technology that eliminates costly membrane replacements. 獨特的固態感測器技術，無需昂貴的薄膜更換
Traditional PVC-membrane ISEs require membrane replacement every 2-3 months. The IntelliCAL ISENO3181 Nitrate 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 幾乎不需維護
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 快速、穩定、準確分析結果
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.
