Water / Wastewater 49 More than just custom solutions for pressure measurement
The Keller standard product catalogue covers most areas of application for pressure measurement technology. However, there are often great benefi ts to optimising pressure sensors specifi cally for use and integration into higher-level complete systems. Keller’s modular product design offers great fl exibility and allows customer-specifi c adaptations to be made without causing soaring costs – even for small production runs.
Keller has been carrying out countless challenging projects in the fi eld of piezoresistive pressure measurement technology for almost 50 years. Even applications that may appear trivial at fi rst glance can prove highly complex upon closer analysis. By taking the actual usage conditions of the sensor into consideration right from the outset, one can achieve major improvements in effectiveness and durability. A mutual exchange of expertise with their customers is therefore central to Keller’s success. Sharing knowledge is what enables Keller to fi nd the best sensor solution. Keller work on a six-stage plan to create the ideal customer specifi c solution. The initial stage is to defi ne basic sensor specifi cations in order to select the appropriate components and then to assess the environmental conditions to determine the appropriate design for the intended location. Having covered the groundwork Keller then design the requested customer-specifi c solution taking all standards and laws into account, assemble the electronic modules, taking into account application-specifi c customer requests and confi gure electrical interfaces and connections. Finally, Keller will customise the product’s labelling using laser engraving or labels
The «Custom Solutions» product category on the Keller website now features everything you need to know about the possibilities and requirements for customer-specifi c product solutions involving pressure measurement technology.

The ‘ultimate photometer’ for
water analysis
For More Info, email: email:
Water ID’s PrimeLab 2.0 photometer offer users more than 140 fl exibly selectable parameters and a sensor setup measuring 18 wavelengths in parallel, which is comparable to conventional high-end photometers in terms of high accuracy. The PrimeLab 2.0 includes a 5.5’’ colour touch HD display as well as a Wi-Fi option to directly, or via mobile phone, communicate with the free and powerful LabCOM® software, app and cloud.
A QR scan camera is also included to scan reagents and detect sampling points. The PrimeLab 2.0 also has the option of connecting electrodes via a small box (“eBOX 1.0”) for pH, EC, TDS, ORP, and temperature to display these results and subsequently help to manage them. The PrimeLab 2.0 provides step-by-step instructions for all parameters on the display, including animated graphics in many different languages.
Various adapters simplify the change between 24 mm/16 mm and 1 ml cuvettes to ensure the best conditions for the different methods. Different cuvettes are needed, for example, for the determination of chlorine, COD, the quantitative and certifi ed 1-hour legionella test or, using the built-in 90° optics, the NTU turbidity, PTSA and fl uorescence. These are just a few of the more than 140 different parameters mentioned that the PrimeLab 2.0 has to offer. A rechargeable 8,400 mA Li-Io battery ensures high performance and a long operating time. Memory in the GB range allows almost unlimited storage of test results, all of which are linked to sampling points that the user can enter individually.
Both sampling points and test results can be immediately uploaded to the free LabCOM® cloud directly or via a mobile phone if either Wi-Fi is enabled or a GSM/USB stick is used; so, measurement data is available worldwide, immediately and password protected. The free LabCOM® app/software/cloud offers the user a wide range of functions, including an admin module. This module warns of measurement results via a traffi c light system, outside the permissible range, or even before measurements that were not carried out, although this would have been necessary. Such “rules” can be individually adapted to the needs of the user.
In combination with the PrimeLab 2.0, Water- i.d.® offers the COD (chemical oxygen demand) test kit as a complete solution for professional COD measurement. It includes the PrimeLab 2.0, Water-i.d.’s COD cell tests, a COD reactor and the Wateri.d. automatic pipettes. By combining the accuracy of the PrimeLab 2.0 photometer with the precise new Water-i.d. COD cell tests, the user is well equipped with the PrimeLab 2.0 COD test kit for accurate determination of chemical oxygen demand in wastewater.

Water Quality Pocket Testers as Accurate as Lab Myron L®
offers a variety of ULTRAPEN™ pocket testers, each featuring simultaneous measurement of Temperature and one critical parameter: PT1 and PTBT1 measure Conductivity, TDS, and Salinity; PT2 and PTBT2 measure pH; PT3 and PTBT3 measure ORP; PT4 and PTBT4 measure Free Chlorine Equivalent (FCE
); PT5 and PTBT5 measure Dissolved Oxygen (DO); PT6 and PTBT6 measure Nitrate.
PT1 and PTBT1 instruments are engineered with a proprietary conductivity cell that delivers accuracy of ±1% of reading and ±0.2% of reading at calibration point.
PT2 and PTBT2 instruments employ a proprietary sensor with a large KCl reservoir for extended life. The user can choose to perform a 1-, 2-, or 3-point calibration. Accuracy is ±.01 pH.
PT3 and PTBT3 proprietary sensors are constructed of a 99.9% pure platinum electrode. There are 3 calibration options with automatic solution recognition. Measurement accuracy is ±10mV.
PT4 and PTBT4 determine the chemical activity of a solution without the hassle and subjectivity of colorimetric and test-strip methods. These instruments feature a proprietary sensor and accuracy of up to±0.3 ppm FCE
™.
PT5 and PTBT5 instruments are accurate to ± 2% of reading with 3 calibration methods: Water Saturated Air; Air Saturated Water; and 0 ppm DO. Readings are adjustable for altitude and salinity and display in concentration, % saturation, or both.
PT6 and PTBT6 measurement method is compatible with EPA Approved Standard Method 4500-NO3— D. The user can select either a 1- or 2-point calibration option and choose from one of 4 standard solutions depending on the application. Readings display as Nitrate, Nitrogen, or mV.
pH, ORP, FCE , DO, and Nitrate sensors are all user replaceable.
Original PT Series instruments feature one-button programmability, measurements, and calibration while the new PTBT Series pairs with most Android™ or iPhone® Bluetooth® enabled devices allowing the user to control settings, measurements, calibrations, and data reporting tools from the PTBTX2™ mobile application. Later, the user can email data in .csv, .xls, .xlsx, or Myron L Company’s proprietary encrypted format, .mlcx, compatible with Guardian2 software.
All ULTRAPENS are compact, lightweight, dust-tight, and waterproof with fully encapsulated electronics and bodies of rugged aircraft aluminum.
