The ammo::lyser can be mounted easily and quickly directly in the medium (in situ) or in a flow cell (monitoring station) and operated via s::can terminals and s::can software. This s::can NH4 probe is ideal for applications in surface water (rivers, lakes), ground water and drinking water, and also for applications in waste water (influent, aeration tank, effluent). The plug and measure principle is at the core of all of s::can’s monitoring systems. Simple and quick installation and start-up, reliable results as soon as the instrument immerses into the water. This simplicity allows the users to work with s::can instruments without extensive training.
However, in addition to its technological advantages, the ammo::lyser is economically convincing. The robust ion-selective membrane typically reaches a service life of 6 months in applications with low NH4 -N concentrations (
The ammo::lyser uses a high performance reference electrode. The clue about this electrode is that the entire outside surface is electrochemically active, it does not significantly drift, even when completely coated, and is therefore superior to conventional ones. Typical problems of conventional pH electrodes such as loss of performance by soiling of a small porous diaphragm or the danger of “bleeding” of the reference electrode are a matter of the past when using the ammo::lyser. Non-porous, non-leaking, stable potential even in extreme applications and no significant fouling, these are unsurpassed properties of the reference electrode, rendering the ammo::lyser unique.
Ammonium measuring precision is ensured by temperature compensation as well as by optional pH and potassium determination. Thanks to the modular design, the ammo::lyser offers the flexibility to suit any application. The housing comprises four electrode slots, the first two of which are naturally used for the reference electrode and the ammonium electrode. The two other slots can be used arbitrarily for pH, nitrate, chloride or potassium compensation electrodes. Determination of pH is essential if this value is subject to fluctuations in the alkaline range, since pH has a direct effect on ammonium. Concurrent determination of potassium is necessary to compensate perturbations of ammonium determination if the potassium value is not stable in the application. Thus, the ammo::lyser is optimally equipped also for applications in the low concentration range (
Insertion or exchange of electrodes, respectively, is about as difficult as changing a light bulb. The design of the housing permits direct access to the electrodes which can be removed easily. This operation can also be performed in the field without any problems.
And the housing is yet another essential point why the ammo::lyser is different. The housing is made out of stainless steel and provides high stability against electromagnetic disturbances. The robust and resilient housing material permits use in industrial applications with aggressive liquids. The sophisticated design without any mobile components drastically reduces malfunctions and maintenance efforts.
Thanks to the design of the probe, coarse contamination cannot hamper the measuring. And for all other contaminations, there is automatic rinsing with pressurized air for reliably removing particles or deposits on the electrodes. Automatic rinsing with pressurized air is successful even in untreated waste water. Thus manual cleaning is not necessary, further reducing maintenance efforts.
Up to now, ion-elective electrodes with reduced performance due to ageing were maintained by replacing the ion-selective membranes and the internal electrolyte of the electrode. These manipulations caused some problems or risks in the field. With the s::can ISE refurbishment, the user does not have to exchange membranes or electrolytes any more, but the complete electrode. Simply send the aged ion-selective electrodes to s::can, and tightly quality controlled ISEs are sent back. The very simple and quick field exchange drastically reduces maintenance time and minimizes risk of damage. The benefits include shorter maintenance times on site as well as the lowest total cost of ownership.
