Description
The pH meter SevenDirect SD20 Kit is a complete laboratory pH measurement set for accurate determination of acidity in aqueous samples. Intended for routine analytical, quality-control and teaching applications, the kit provides the core instrument platform needed for standard pH electrode work on the laboratory bench. It is supplied as one set with a net weight of 3,2 kg and a gross weight of 4,5 kg, ensuring a stable yet manageable package for daily use. Manufactured by Mettler-Toledo OnLine, the SevenDirect SD20 Kit serves laboratories that require a dedicated pH meter rather than a multi-parameter system. Typical tasks include buffer verification, sample pH profiling and process monitoring in chemical, pharmaceutical and environmental laboratories. The kit format simplifies procurement and setup, delivering the meter ready for integration with compatible electrodes and accessories. Country of origin is China, and the unit carries WEEE registration DE39797539. With its focused pH capability and kit configuration, the SevenDirect SD20 offers a practical entry point for laboratories building or renewing their electrochemical measurement capacity.

Questions about pH meter SevenDirect SD20 Kit
What is this article?
pH meter SevenDirect SD20 Kit is the article on this page. Luminix Health distributes Mettler-Toledo OnLine for laboratory use. It sits in pH meters, inside pH & electrochemistry, in Lab instruments.
A pH meter reads the electrode and displays pH, after calibration with at least two buffers. A meter that cannot be calibrated is a voltmeter. Resolution to 0.001 is not the same as accuracy. Portable and benchtop meters differ in the electrodes they accept and in the data they store.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
