 Parameter / Ozone 

Basics

ozone molecule

Ozone is an instable molecule of three Oxygen atoms and a very strong oxydising agent. At room temperature it is a gas. Due to its instability it cannot be stored in pressurised cylinders and has to be prepared on site.

 

 

Effect

Ozone is an eco-friendly disinfectant. However, its great disinfection strength can only be used to good advantage in suitable reactors with a sojourn time of at least three minutes. The long-term effect of Ozone is only a few minutes.

 

Applications

Ozone is commonly used for the treatment of drinking water and swimming pool water, to reduce the organic load, often in combination with filtration, and to remove inorganic substances such as iron and manganese. Ozone is also used for the disinfection of process water, air washers and air conditioning. In industrial applications it is sometimes used to detoxicate difficult waste water containing chelated metals and cyanides.

 

Dr. A. Kuntze measurement

diagram sensor

We measure ozone potentiostatically with measuring and counter electrodes of pure gold and a Ag/AgCl reference. The measurement shows good selectivity towards ozone. A precise potential is applied to the measuring electrode, leading to an accumulation of negative charges on the metal surface.Ozone molecules that hit the surface take a defined portion of the charge with them. The controller measures the potential between measuring and reference electrode and readjusts the charge on the electrode surface. The current necessary to maintain a constant charge is a direct measure for the concentration of ozone. The sensor design with three electrodes in a single rod enables us to use our patendted cleaning procedure ASR providing you with a low-maintenance measuring set-up. Get more information on ASR.

 

You would like to monitor the ozone concentration in your process?

We recommend our Krypton K: a complete measuring system with all necessary components, including a sampling point!

For a more individual set-up select an instrument – either K 100 ClO2 for panel installation or K 100 W ClO2 with wall-mounting housing -, our membrane-free sensor AuAu-600-OO-2-1-PG, a flow assembly GD 3VG with defined incident flow, a sensor cable 5 SCR-M12-AE-X, and – if desired – our patented sensor cleaning ASR (cable included). We will be delighted to help you! Give us a call: +49 (0) 2150-7066-0

You would like to monitor the ozone in ambient air?

We recommend our K 100 (W) Gas. You can connect one or two gas sensors type GE 760 O3. The diagram shows a typical measuring set-up to monitor the ambient air in storage rooms.

gas measuring point

For each sensor two limit values can be defined, which operate separate relays. The first is supposed to activate an acoustic signal: by overstepping the limit value the alarm is set off. Manual acknowledgement switches off the relay. The second is supposed to activate the sprinkling system. A dela ycan be adjusted so that the sprinkling system starts only if the limit value is exceeded for a certain time. This relay can be switched off by digital input: if you connect a door contact, the sprinkling system will be switched off as soon as the maintenance personnel opens the door.

 


Plug & Play...
Our measuring systems for disinfectants contain all neccessary components and are equipped with safety features that allow a smooth measurement.

Pressure-resistant...

You don´t need to discard your measurement water any more. Thanks to our pressure-resistant sensors and assemblies you can redirect the water into the piping.

Self-cleaning...

Maintenance is greatly reduced by our automatic sensor cleaning ASR. ASR keeps the electrode surfaces clean simply and environmental-friendly by electrolysis of water. More Information about ASR
