Calibration and cleaning tool for sensor modules Drinking water as a food product must be precisely monitored in terms of area supply but also in the chemical, pharmaceutical, food and beverage industry. Thanks to the proven Online Analysis System Type 8905 from Bürkert, it is possible to measure all WRITTEN BY Burkert www.burkert.co.uk/en simultaneously in fixed cycles, a mobile variant is now available - the battery-operated handheld cleaning and calibration tool MZ15. It enables relevant parameters. simple manual cleaning and/or The modular system offers space for in the field without having to go to up to six sensor cubes for, among others, ORP (oxidation reduction potential or redox potential), pH value, chlorine, turbidity and conductivity measurements. Depending on the water quality, these sensors need to be cleaned at regular intervals in order to remove limescale, iron or organic deposits and, if necessary, recalibrated. In addition to the present, permanently installed automatic cleaning system MZ20, which cleans all sensors 42 FDPP - www.fdpp.co.uk calibration of individual sensor cubes the trouble of handling reagents. The user can now respond quickly and in a the tanks with cleaning liquid and, if needed, calibration solution are integrated in the handheld tool. The system has been optimised to guarantee low chemical consumption. The required liquids for cleaning or calibration are simply filled into the tanks. The hot swap-capable sensor cubes are then removed individually from the analysis system during operation, inserted into the cleaning needs-oriented manner to sensor drift tool, subsequently cleaned and, if and contamination and set flexible needed, calibrated by the system and cleaning or calibration intervals, e.g. finally re-inserted into the Online to meet company and user-specific Analysis System. Via the standard quality standards. interface of the Bürkert device The lightweight handheld tool is available as a basic version for cleaning and as an extended version that enables both cleaning and recalibration. To ensure easy handling, platform EDIP, based on CANopen, the MZ15 can be connected to a 7” touch screen or a PC with the Bürkert Communicator software. This enables quick and simple calibration and facilitates documentation tasks.
