• ISE refurbishment – the easy way to minimise maintenance
• easy & quick mounting and measurement directly in the media (InSitu) or in the flow cell (monitoring station)
• operation via s::can terminals & s::can software
• automatical temperature compensation, pH compensation possible
• ideal for surface water, ground water and drinking water, also for applications in waste water
• minimal maintenance
• a life time of ISE: typically six months (for applications <1mg/l NH4-N), resp. 1 to 2 years (for applications >1mg/l NH4-N)


The ammo::lyser sensor is ideal for applications in surface water (rivers, lakes), ground water, drinking water, and for applications in wastewater (influent, aeration tank, effluent). The plug and measure principle is at the core of all of sensors monitoring systems. Straightforward and quick installation and start-up, reliable results as soon as the instrument immerses into the water. This simplicity allows the operator to work with our devices without extensive training.

The s::can range measures a wide range of parameters in numerous applications. All s::can measuring instruments are developed with the same philosophy in mind: They are intelligent, robust and require little to no maintenance.

The s::can spectrometer probes from PMA Ltd operate using the same measuring principle: Spectrometry. The spectrometer probes are the first and only instruments in the world that can measure optical spectra from 190 to 720 nm directly in liquid media. The materials contained in the medium deteriorate a light beam emanated by a lamp that transfers through the liquid. After contact, its intensity is measured by a sensor over a variety of wavelengths specific to the application.
