Ammonia Sensor Exporter
This probe is used to measure ammonia (NH3) in aqueous solutions. In an aqueous solution, ammonia is in a pH dependent balance with ammonia ions (NH4+-Ionen). If the NH4+ ions are transformed into ammonia by the addition of a caustic solution, the probe will record the resulting ammonia. NH4+ ions as such will not be recorded. The ammonia sensor comprises a pH glass electrode and a reference electrode. Both electrodes are immersed in an electrolyte. The electrolyte is separated from the medium to be measured by a hydrophobic gas permeable membrane. The pH value of the electrolyte changes by NH3 gas permeating the hydrophobic membrane. This local change of the pH value is measured by the integrated pH electronic at a resistance. The advantage of the JUMO ammonia probe is the availability of pre-fabricated membrane caps. Manual attachment of the sensitive membrane is not required. The membrane cap of the JUMO probe is easily and quickly replaced as a compelete unit.
Bromin Sensor Exporter
The disinfectant bromine offers a greater disinfectant effect at higher pH values compared to chlorine compounds while at the same time having a lower corrosive effect.Abreacted bromine solutions irritate the mucous membranes to a lesser extent and have a neutral odor.
The membrane-covered, amperometric sensor works on the three-electrode principle. The device is used for the online measurement of hypobromous acid (HOBr). Suitable bromination methods include free bromine (HOBr) as well as 1-bromine-3-chlorine-5.5-dimethyl-hydantoin (BCDMH).

Chlorine Dioxide and Ozone
These membrane-covered amperometric sensors are used to measure the concentration of chlorine dioxide or ozone in aqueous solutions (e.g. drinking water, swimming pool water, industrial water, process water, and cooling water). The sensor for chlorine dioxide can be used to measure chlorine dioxide from chlorite/chlorine and chlorite/hydrochloric acid plants. The sensor for ozone can be used to measure electrolytically generated ozone among other things. The sensors are not suitable for detecting the absence of chlorine dioxide or ozone. The integrated electronics of the sensors provide a temperature-compensated current signal of 4 to 20 mA. A downstream device (indicator, controller, recorder, PLC, etc.) is used for calibration. The sensors can be connected directly to a suitable display and control device
Total Chlorine
Total chlorine is the sum of combined and free chlorine. In all instances, the level of total chlorine will always be above or equal to free chlorine levels. The most common levels of free chlorine present in drinking water are 0.2 to 2.0 mg/L, but can be up to 5.0 mg/L. Total chlorine is usually measured in wastewater that has undergone treatment.
This membrane-covered amperometric sensor is used to measure the total chlorine concentration in water. The sensor also measures "free chlorine" from anorganic chlorine products (chlorine gas, hypochlorite, etc.) and "combined chlorine" (e.g. chloramine). This sensor can only be used in media with drinking or swimming pool water quality. Typical areas of application include swimming pools and monitoring of drinking water.
Concentration Transmitter
The device is used for measurement/control of the conductivity/concentration of fluid medium. The application is particularly recommended in media in which severe deposits through contamination, oil, grease, or plaster/calcium precipitations are to be expected. The integrated temperature measurement allows a precise and quick temperature compensation that is particularly important when measuring the conductivity. Additional functions, such as the combined toggling of measuring range and temperature coefficient, allow the optimum use in CIP processes. Two integrated switching outputs can be freely programmed for limit value monitoring of conductivity/concentration and/or temperature. Alarm and control tasks (desalination) can also be assigned.

ph Sensor Combination Electrodes
A pH measurement loop is made up of three components, the pH sensor, which includes a measuring electrode, a reference electrode, and a temperature sensor; a preamplifier; and an analyser or transmitter. A pH measurement loop is essentially a battery where the positive terminal is the measuring electrode and the negative terminal is the reference electrode. The measuring electrode, which is sensitive to the hydrogen ion, develops a potential (voltage) directly related to the hydrogen ion concentration of the solution. The reference electrode provides a stable potential against which the measuring electrode can be compared.

Redox Sensor
ORP is measured using an electrochemical sensor called an ORP or REDOX sensor. Similar to to pH sensors, the most common type of ORP sensor is a combination sensor with a measuring electrode and a reference electrode. The measuring cell, typically a noble metal like platinum or gold, detects changes in REDOX potential, while the reference provides a stable comparison signal.
Like a pH measurement, an ORP measurement is not a direct indicator of concentration, but rather an indicator of activity. However, in solutions with one active species, like pool water containing chlorine, ORP correlates to concentration.

Dissolved Oxygen Sensor
Optical dissolved oxygen sensors feature replaceable caps containing the sensing element: a special dye that will luminesce (glow red) when exposed to light of a particular wavelength. The dye is covered by an oxygen permeable paint layer, which allows oxygen molecules to interact with the dye, while protecting it from other sample constituents. Oxygen interferes with the dye’s luminescence (intensity and lifetime). The sensor emits light and measures the resultant luminescence with a photodiode. This reading is compared to a reference reading using light of a different wavelength. The measurement and reference values are compared to calculate dissolved oxygen in the sample.

Turbidity Sensor
Turbidity sensors measure the amount of light that is scattered by the suspended solids in water. As the amount of total suspended solids (TSS) in water increases, the water’s turbidity level (and cloudiness or haziness) increases. Turbidity sensors are used in river and stream gaging, wastewater and effluent measurements, control instrumentation for settling ponds, sediment transport research, and laboratory measurements.
