Analyzer Expert-001-milk
Liquid analyzer Expert-001 is a modern multi-parameter device designed to solve many analytical problems using just one analyzer. The device is compatible with ion-selective and pH electrodes. Intuitive user interface. Calibration is carried out with solutions. Measurement results are calculated automatically. Allows you to store up to 32 calibrations in the device’s memory. The analyzer allows you to select an isopotential point for automatic temperature compensation. Can be connected to a PC. The device provides autonomous operation due to the built-in powerful lead-acid battery or operation from the mains. The LCD screen displays all the specified parameters, as well as the charging level of the device. Designed to measure: indicator of ion activity (pH and рХ) and calculation of their molar (C) and mass (Cm) concentrations; electromotive force (EMF) of electrode systems (in particular, redox potential (Eh); temperature (T); mass concentration of dissolved oxygen and/or BOD. Objects of analysis: drinking, natural, waste water aqueous solutions of samples of plant, food products, soils, etc. Applications: laboratories of industrial enterprises and research institutions control, inspection and supervision bodies workshops of universities, etc. Advantages of Expert-001: Electrode compatibility; Equipped with oxygen sensors; User-friendly interface; Calibration with solutions; Automatic calculation of measurement results in mV, рХ, М, mg/l; Storing values in memory; Selecting an isopotential point; PC output.
