Ammonium (NH₄⁺) Combined Ion Selective Electrode 972122

Overview

The ammonium ion selective electrode 972122 is a combined electrode. In other words, the pvc membrane replaceable sensing element and the reference half-cell share one Φ12 × 120 mm body. As a result, your meter needs only a single BNC(Q9) connector — no separate reference electrode and no second cable.

Specifically, it measures NH₄⁺ from 1 × 10⁻⁶ – 1.0 M (17 µg/L – 17 g/L). Moreover, it works from 0 – 40 °C and at a pH of 2 – 9. Refillable reference. The junction is a movable plastic grinding mouth. However, K⁺, Na⁺, Cs⁺ interfere. Finally, it pairs with any ion meter, for example the M310F multi-parameter analyser, or with an automatic titrator.

Applications

This electrode serves wastewater-treatment monitoring, aquaculture and surface-water surveys. Therefore, calibrate it with standards that bracket your sample for accurate results. In addition, keep sample and standards at the same temperature.

Why buy the ammonium ion selective electrode 972122 from Hadron Group

Hadron Group runs its own water laboratory in Pretoria. In addition, we supply analytical instruments to municipal, mining, food and industrial laboratories across South Africa and the SADC region. We stock the electrodes we use ourselves. Moreover, calibration standards, filling solutions and replacement membranes are available for every model. Finally, we help you match the electrode to your meter before you order.

Frequently asked questions

How do I order the ammonium ion selective electrode 972122? Quote the model number and your meter. In addition, tell us which standards and filling solutions you need, and we will quote the set.

Do I need a separate reference electrode? No. The reference half-cell sits in the same body. Therefore you simply connect the single BNC(Q9) plug to the ion (mV) input of your meter.

Which meters is it compatible with? In short, any ion meter, pH/mV meter with an ISE mode, or titrator with a BNC(Q9) input. For field work, for example, the M310F multi-parameter analyser (pH, EC, ISE, DO) has a dedicated ISE mode.

What is the measuring range in concentration units? The range is 1 × 10⁻⁶ – 1.0 M. In other words, it corresponds to 17 µg/L – 17 g/L.
