Wireless freedom in pH measurement! 827 pH lab 826 pH mobile Two meters – one philosophy… wipHi – wireless communication with printer and PC «Point and print» Do you require for your documentation a printout of the measuring parameters in DIN A4 format and a small label that you want to stick onto your sample vessel? Just point the built-in IrDA interface at the corresponding IrDA-compatible printer* and there you go – without any bothersome changing of cable connections and without having to adapt any printing parameters. Data transfer to the PC/LIMS The IrDa interface of a notebook or the optional IrDA adapter for RS 232 or USB interfaces makes it possible to transfer raw data directly to a computer or a LIMS*. 2 compHort – designed for easy operation Form and function Quality «Made in Switzerland» that you can see and feel. The modern design and the high-quality materials of our new pH Meters will meet your high expectations. Easy operation No confusing pictograms, but a well-structured multiple-line display. The cursor keys combined with the comfortable menu dialog provide easy access to the numerous functions of the new pH Meters. 3 pHidelity – «Swiss Made» technology that you can rely on Small but smart – the measuring input The newly developed measuring input represents top technology that is normally only encountered in higher price ranges. It supplies an extremely low-noise signal and is easily capable of providing a resolution of 0.001 pH. pH calibration with automatic buffer recognition Calibration can be carried out with up to three buffers and is very easy, thanks to the automatic buffer recognition and temperature correction. You can enter limit values for the slope and asym-metry potential; via the calibration interval you determine when the electrode is to be next calibrated. Of course, you can call up the calibration data at any time and output them in a separate report. If you want to be entirely on the safe side, you can also lock the key upon comple-tion of the calibration. GLP – user and samples clearly identified An identification can be entered for each user and each sample. This identification appears then in the report header or together with the measured value in the measured-value memory to ensure that a measurement can be clearly assigned later on. Comparable measured values The following options are available for the acquisition of measured values: • immediately • drift-controlled • after a predefined time interval • after reaching a predefined difference to the previous measured value During the measurement, the measured values can be sent to a printer or PC or stored in a result memory that has a capacity of 200 measured values. On the multiple-line LCD display you can see all important information at a glance. Any error occurring is clearly indicated by an easy-to-grasp warning message. 4 5 826 pH mobile – GLP at any time and anywhere The battery-powered 826 pH mobile is ideal for labs, production plants and field measurements: Simply use it whenever and wherever you want to measure a pH value. The 6.0228.020 Primatrode combined pH glass electrode with robust plastic shaft and NTC temperature sensor is equipped with a fixed cable with type I plug. Combined with this pH electrode, the housing of the 826 pH mobile corresponds to protection class IP67, which means that the 826 pH mobile can be used in extremely humid environments subject to splash water. Even if the instrument should brief-ly become immersed in water, its functioning will not be affected. The 827 pH lab includes either the Primatrode or the Unitrode. The Primatrode with NTC temperature sensor (6.0228.010) is especially suitable for routine GLP conforming pH measurements in clear aqueous solutions. The Unitrode with Pt1000 (6.0258.600) is for universal use and insensitive to contamination thanks to its fixed ground-joint diaphragm. 6 826 pH mobile – the mobile lab The 826 pH mobile is also available in a completely equipped carrying case that contains buffer solutions, measuring vessels and sample bottles – in short everything you need for field measurements. In addition, the case can also be used as a working surface. 7 827 pH lab – stable and reliable The line-powered 827 pH lab is a reliable companion for the daily lab work. The metal stand rod attached to the base plate and the most advanced electronics inside the instrument guarantee measured values that are stable in every respect. The 827 pH lab includes either the Primatrode or the Unitrode. The Primatrode with NTC temperature sensor (6.0228.010) is especially suitable for routine GLP conforming pH measurements in clear aqueous solutions.
