Comparator Reliable Water Testing equipment One test and one blank cuvette Precise ongoing colour scale (colour disc) Rapid dissolving Water-i.d. ® tablet reagents More than 40 different parameter|methods|discs available boiler water Cooling water Waste Water Pools Drinking Water Food processing Marine Rapid Tests Water-i.d. ® comparators provide you with access to semi- professional water analysis. While comparators are – like Pooltesters – visual measure - ment devices, the arrangement of the measured colour to the scale – and the determination of the measurement va - lue – is much more precise with comparators because the measurement is compared to a rotating, ongoing colour scale (colour disc). There are no measurement results “between” individual colour scales. Ergonomic design and high quality materials also simplify measurements. So far, 43 different parameter can be tested with the same basic model. Just a different disc and reagents are needed to extend your Comparator-Kit. Each Water-i.d. ® Comparator-Kit comes in a grey plastic case with foam insert, including a basic Comparator de - vice, at least 2x square 10ml plastic cuvettes, a stirring rod, a cleaning brush and reagents (tablets, liquids or powders, depending on the parameter) to perform at least 30 tests. 40 Active Oxyg.

While FlexiTesters ® are – like Pooltesters – visual measu - rement devices, the arrangement of the measured co - lour to the scale – and the determination of the measu - rement value – is much more precise with FlexiTesters ® because the measurement is compared to an ongoing colourscale on a parameter–stick. There are no measurement results “between” indivi - dual colour scales. Ergonomic design and high quality materials also simplify measurements. So far, 43 diffe - rent parameter-methods can be tested with the same basic model. Just a different paramter-stick and reagents are nee - ded to extend your FlexiTester ® kit. 42 Active Oxyg.

Microbiological Tests The definition of a dipslide is a means of testing the micro - bial content of liquids or surfaces. It consists of a plastic car - rier bearing a sterile culture medium which can be dipped in the liquid or pressed on to the surface to be sampled. It is than incubated for 48 hours at a specific temperature to allow microbial growth. The resulting microbial colonies are estimated by reference to a chart. If the treatment pro - gramme is effective, the dipslide count will be consistently low (<10 4 ). If a high result is obtained, the test should be repeated and the treatment programme checked. Each Water-i.d. ® Dipslide pack contains 10 dipslides along with a comparison chart to obtain the test result.

Legionella Test–Kits 1–Hour Legionella spp. Test Detects only living Legionella Quantitative 60–10 6 CFU AOAC Certified All–in–one case Kit–Features: boiler water Cooling water Drinking Water Marine Laboratories Microbiological Tests Legionella Basic Kit Water-i.d.® introduces a new, patented method to test via - ble Legionella Sp. in just one hour without the need to let bacteria grow! Legionella bacteria, in special Legionella pneumorphila serogroup 1, is a harmful threat with a mortality rate of up to 30%. Once Legionella are inhaled (droplets in the air), they grow in human lungs and can cause Pontiac fever or even Pneumonia (Legionnaire‘s disease). The issue with current method (culture) is that it takes up to 14 days to let Legionella grow on a petri dish to be visble and countable, which is far too long to allow effective actions. Legipid ® on PrimeLab 2.0 takes a different approach: As with the culture method, 1 litre of water is filtered to col - lect the Legionella. After the Legionella are released f rom the filter, a patented reagent is added that contains micro- bits with a magnetic core covered with an antibody. Only living Legionella spp. (no false positives!) are captured by the antibodies. After several washing steps, a colour tra - cer, also linked to an antibody, is added, which binds with the Legionella spp. already bound to the micro-bit. This makes viable Legionella visible (pink colour) to be detec - ted by the PrimeLab. The PrimeLab measures the colour and converts it to 60 – 10 6 into Colony Founding Units (CFU). As the PrimeLab is connected via WiFi|USB|Bluetooth ® to a f ree software and app, both of which are synchronised via the cloud, re - porting is very easy. In addition, the PrimeLab can perform more than 140 different parameter methods f rom ammo - nia to zinc. A true “one for all“. Basic Kit (Auto-Filtration | max. 9 tests*): This Basic Kit is suitable if Legionella tests are only carried out f rom time to time and contains reagents for up to 9 tests.

While conventional photometers only perform tests at selected wavelengths, the Primelab can also receive data f rom 18 different wavelengths in parallel and thus covers the most important parts of the UV and IR range as well as the entire VIS range. Corresponding LEDs are posi - tioned at both 180° and 90° to also allow NTU turbidity, PTSA and fluorescein measurements. Very narrow peaks between 390 and 950 nm enable the most accurate rea - dings, close to the performance of a spectrophotometer. The highly professional PrimeLab 2.0 firmware interpo - lates between the different wavelengths, while some parameter curves are set to use multiple wavelengths to obtain the most accurate test results. For each individual parameter method, there are step-by-step instructions in many different languages, as well as useful animations and links to user videos to ensure that the correct and proper procedure is followed. Like the PrimeLab 1.0, the PrimeLab 2.0 offers a flexible parameter setup with all the options to upgrade as nee - ded. The PrimeLab 2.0 offers more than 140 different parameters/methods, covering the needs of many diffe - rent industries. With its built-in camera, the PrimeLab 2.0 offers the ability to scan QR-codes to identify accounts (sampling points or locations) set up by the user and to identify reagents with QR-code on the packaging. 4 Advantages of these options are: - Scanning the QR-code of a sampling site ensures that you always link the test results you receive to the correct account. This shortens the testing process as the associated acount is automatically selected. - Scanning QR-codes on reagent packaging prevents the wrong or even expired reagents f rom being used and speeds up the testing process by pre-selecting the parame - ter method. Over time, water analysis has become much more than just a test. Real-time availability of reliable test results and data management are as important as the test results themsel - ves. The PrimeLab 2.0 is the ultimate in connectivity! With WiFi–USB–GSM**(via USB modem) there are several ways to connect the PrimeLab 2.0 to a smartphone, tablet, compu - ter or directly to the LabCOM ® cloud. Wherever the tests are carried out, whether it is in the lab, on site or on a ship, inside a cooling tower – in fact anywhere – the data can be transferred easily and automatically. Scan me!

24. Simple dosing reagents Various parameters and kits Turbidity method tablet count method (titration) Yes|No method Mini–Kits boiler water Cooling water Waste Water Pools Drinking Water Food processing Marine Rapid Tests 44 Some Water-i.d. ® Mini Kits are based on the tablet coun - ting method, in which tablets are added to the water until the colour changes in a defined way. The amount of added tablets is entered into a formula to determine the measured value. The innovative Water-i.d. ® tablet push- through blisters simplify the procedure. In the turbidity method, the water sample becomes turbid after the reagent is added. The intensity of the turbidity determines the value. In the yes/no test method, a dis - tinction is made between 2 different colours. Depending on which colour develops, the parameter is present in the sample or not. All the titration and turbidity methods and the yes/no test are simple and proven measuring met - hods for determining water values.
